      8  DESCRIPTION
      9  -----------
     10 
     11  The OpenSSL Project is a collaborative effort to develop a robust,
     12  commercial-grade, fully featured, and Open Source toolkit implementing the
     13  Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1)
     14  protocols as well as a full-strength general purpose cryptography library.
     15  The project is managed by a worldwide community of volunteers that use the
     16  Internet to communicate, plan, and develop the OpenSSL toolkit and its
     17  related documentation.
     18 
     19  OpenSSL is based on the excellent SSLeay library developed from Eric A. Young
     20  and Tim J. Hudson.  The OpenSSL toolkit is licensed under a dual-license (the
     21  OpenSSL license plus the SSLeay license) situation, which basically means
     22  that you are free to get and use it for commercial and non-commercial
     23  purposes as long as you fulfill the conditions of both licenses.
     24 
     25  OVERVIEW
     26  --------
     27 
     28  The OpenSSL toolkit includes:
     29 
     30  libssl.a:
     31      Implementation of SSLv2, SSLv3, TLSv1 and the required code to support
     32      both SSLv2, SSLv3 and TLSv1 in the one server and client.
     33 
     34  libcrypto.a:
     35      General encryption and X.509 v1/v3 stuff needed by SSL/TLS but not
     36      actually logically part of it. It includes routines for the following:

     38      Ciphers
     39         libdes - EAY's libdes DES encryption package which has been floating
     40                  around the net for a few years.  It includes 15
     41                  'modes/variations' of DES (1, 2 and 3 key versions of ecb,
     42                  cbc, cfb and ofb; pcbc and a more general form of cfb and
     43                  ofb) including desx in cbc mode, a fast crypt(3), and
     44                  routines to read passwords from the keyboard.

    115 
    116  INSTALLATION
    117  ------------
    118 
    119  To install this package under a Unix derivative, read the INSTALL file.  For
    120  a Win32 platform, read the INSTALL.W32 file.  For OpenVMS systems, read
    121  INSTALL.VMS.
    122 
    123  Read the documentation in the doc/ directory.  It is quite rough, but it
    124  lists the functions; you will probably have to look at the code to work out
    125  how to use them. Look at the example programs.
    126 
    127  PROBLEMS
    128  --------
    129 
    130  For some platforms, there are some known problems that may affect the user
    131  or application author.  We try to collect those in doc/PROBLEMS, with current
    132  thoughts on how they should be solved in a future of OpenSSL.
    133 
    134  SUPPORT

README.ENGINE

      1   ENGINE
      2   ======
      3 
      4   With OpenSSL 0.9.6, a new component was added to support alternative
      5   cryptography implementations, most commonly for interfacing with external
      6   crypto devices (eg. accelerator cards). This component is called ENGINE,
      7   and its presence in OpenSSL 0.9.6 (and subsequent bug-fix releases)
      8   caused a little confusion as 0.9.6** releases were rolled in two
      9   versions, a "standard" and an "engine" version. In development for 0.9.7,
     10   the ENGINE code has been merged into the main branch and will be present
     11   in the standard releases from 0.9.7 forwards.
     12 
     13   There are currently built-in ENGINE implementations for the following
     14   crypto devices:
     15 
     16       o CryptoSwift
     17       o Compaq Atalla
     18       o nCipher CHIL
     19       o Nuron
     20       o Broadcom uBSec
     21 
     22   In addition, dynamic binding to external ENGINE implementations is now
     23   provided by a special ENGINE called "dynamic". See the "DYNAMIC ENGINE"
     24   section below for details.
     25 
     26   At this stage, a number of things are still needed and are being worked on:
     27 
     28       1 Integration of EVP support.
     29       2 Configuration support.
     30       3 Documentation!
     31 
     32 1 With respect to EVP, this relates to support for ciphers and digests in
     33   the ENGINE model so that alternative implementations of existing
     34   algorithms/modes (or previously unimplemented ones) can be provided by
     35   ENGINE implementations.
     36 
     37 2 Configuration support currently exists in the ENGINE API itself, in the
     38   form of "control commands". These allow an application to expose to the
     39   user/admin the set of commands and parameter types a given ENGINE
     40   implementation supports, and for an application to directly feed string
     41   based input to those ENGINEs, in the form of name-value pairs. This is an
     42   extensible way for ENGINEs to define their own "configuration" mechanisms
     43   that are specific to a given ENGINE (eg. for a particular hardware
     44   device) but that should be consistent across *all* OpenSSL-based
     45   applications when they use that ENGINE. Work is in progress (or at least
     46   in planning) for supporting these control commands from the CONF (or
     47   NCONF) code so that applications using OpenSSL's existing configuration
     48   file format can have ENGINE settings specified in much the same way.
     49   Presently however, applications must use the ENGINE API itself to provide
     50   such functionality. To see first hand the types of commands available
     51   with the various compiled-in ENGINEs (see further down for dynamic
     52   ENGINEs), use the "engine" openssl utility with full verbosity, ie;
     53        openssl engine -vvvv
     54 
     55 3 Documentation? Volunteers welcome! The source code is reasonably well
     56   self-documenting, but some summaries and usage instructions are needed -
     57   moreover, they are needed in the same POD format the existing OpenSSL
     58   documentation is provided in. Any complete or incomplete contributions
     59   would help make this happen.
     60 
     61   STABILITY & BUG-REPORTS
     62   =======================
     63 
     64   What already exists is fairly stable as far as it has been tested, but
     65   the test base has been a bit small most of the time. For the most part,
     66   the vendors of the devices these ENGINEs support have contributed to the
     67   development and/or testing of the implementations, and *usually* (with no
     68   guarantees) have experience in using the ENGINE support to drive their
     69   devices from common OpenSSL-based applications. Bugs and/or inexplicable
     70   behaviour in using a specific ENGINE implementation should be sent to the
     71   author of that implementation (if it is mentioned in the corresponding C
     72   file), and in the case of implementations for commercial hardware
     73   devices, also through whatever vendor support channels are available.  If
     74   none of this is possible, or the problem seems to be something about the
     75   ENGINE API itself (ie. not necessarily specific to a particular ENGINE
     76   implementation) then you should mail complete details to the relevant
     77   OpenSSL mailing list. For a definition of "complete details", refer to
     78   the OpenSSL "README" file. As for which list to send it to;
     79 
     80      openssl-users: if you are *using* the ENGINE abstraction, either in an
     81           pre-compiled application or in your own application code.
     82 
     83      openssl-dev: if you are discussing problems with OpenSSL source code.
     84 
     85   USAGE
     86   =====
     87 
     88   The default "openssl" ENGINE is always chosen when performing crypto
     89   operations unless you specify otherwise. You must actively tell the
     90   openssl utility commands to use anything else through a new command line
     91   switch called "-engine". Also, if you want to use the ENGINE support in
     92   your own code to do something similar, you must likewise explicitly
     93   select the ENGINE implementation you want.
     94 
     95   Depending on the type of hardware, system, and configuration, "settings"
     96   may need to be applied to an ENGINE for it to function as expected/hoped.
     97   The recommended way of doing this is for the application to support
     98   ENGINE "control commands" so that each ENGINE implementation can provide
     99   whatever configuration primitives it might require and the application
    100   can allow the user/admin (and thus the hardware vendor's support desk
    101   also) to provide any such input directly to the ENGINE implementation.
    102   This way, applications do not need to know anything specific to any
    103   device, they only need to provide the means to carry such user/admin
    104   input through to the ENGINE in question. Ie. this connects *you* (and
    105   your helpdesk) to the specific ENGINE implementation (and device), and
    106   allows application authors to not get buried in hassle supporting
    107   arbitrary devices they know (and care) nothing about.
    108 
    109   A new "openssl" utility, "openssl engine", has been added in that allows
    110   for testing and examination of ENGINE implementations. Basic usage
    111   instructions are available by specifying the "-?" command line switch.
    112 
    113   DYNAMIC ENGINES
    114   ===============
    115 
    116   The new "dynamic" ENGINE provides a low-overhead way to support ENGINE
    117   implementations that aren't pre-compiled and linked into OpenSSL-based
    118   applications. This could be because existing compiled-in implementations
    119   have known problems and you wish to use a newer version with an existing
    120   application. It could equally be because the application (or OpenSSL
    121   library) you are using simply doesn't have support for the ENGINE you
    122   wish to use, and the ENGINE provider (eg. hardware vendor) is providing
    123   you with a self-contained implementation in the form of a shared-library.
    124   The other use-case for "dynamic" is with applications that wish to
    125   maintain the smallest foot-print possible and so do not link in various
    126   ENGINE implementations from OpenSSL, but instead leaves you to provide
    127   them, if you want them, in the form of "dynamic"-loadable
    128   shared-libraries. It should be possible for hardware vendors to provide
    129   their own shared-libraries to support arbitrary hardware to work with
    130   applications based on OpenSSL 0.9.7 or later. If you're using an
    131   application based on 0.9.7 (or later) and the support you desire is only
    132   announced for versions later than the one you need, ask the vendor to
    133   backport their ENGINE to the version you need.
    134 
    135   How does "dynamic" work?
    136   ------------------------
    137     The dynamic ENGINE has a special flag in its implementation such that
    138     every time application code asks for the 'dynamic' ENGINE, it in fact
    139     gets its own copy of it. As such, multi-threaded code (or code that
    140     multiplexes multiple uses of 'dynamic' in a single application in any
    141     way at all) does not get confused by 'dynamic' being used to do many
    142     independent things. Other ENGINEs typically don't do this so there is
    143     only ever 1 ENGINE structure of its type (and reference counts are used
    144     to keep order). The dynamic ENGINE itself provides absolutely no
    145     cryptographic functionality, and any attempt to "initialise" the ENGINE
    146     automatically fails. All it does provide are a few "control commands"
    147     that can be used to control how it will load an external ENGINE
    148     implementation from a shared-library. To see these control commands,
    149     use the command-line;
    150 
    151        openssl engine -vvvv dynamic
    152 
    153     The "SO_PATH" control command should be used to identify the
    154     shared-library that contains the ENGINE implementation, and "NO_VCHECK"
    155     might possibly be useful if there is a minor version conflict and you
    156     (or a vendor helpdesk) is convinced you can safely ignore it.
    157     "ID" is probably only needed if a shared-library implements
    158     multiple ENGINEs, but if you know the engine id you expect to be using,
    159     it doesn't hurt to specify it (and this provides a sanity check if
    160     nothing else). "LIST_ADD" is only required if you actually wish the
    161     loaded ENGINE to be discoverable by application code later on using the
    162     ENGINE's "id". For most applications, this isn't necessary - but some
    163     application authors may have nifty reasons for using it. The "LOAD"
    164     command is the only one that takes no parameters and is the command
    165     that uses the settings from any previous commands to actually *load*
    166     the shared-library ENGINE implementation. If this command succeeds, the
    167     (copy of the) 'dynamic' ENGINE will magically morph into the ENGINE
    168     that has been loaded from the shared-library. As such, any control
    169     commands supported by the loaded ENGINE could then be executed as per
    170     normal. Eg. if ENGINE "foo" is implemented in the shared-library
    171     "libfoo.so" and it supports some special control command "CMD_FOO", the
    172     following code would load and use it (NB: obviously this code has no
    173     error checking);
    174 
    175        ENGINE *e = ENGINE_by_id("dynamic");
    176        ENGINE_ctrl_cmd_string(e, "SO_PATH", "/lib/libfoo.so", 0);
    177        ENGINE_ctrl_cmd_string(e, "ID", "foo", 0);
    178        ENGINE_ctrl_cmd_string(e, "LOAD", NULL, 0);
    179        ENGINE_ctrl_cmd_string(e, "CMD_FOO", "some input data", 0);
    180 
    181     For testing, the "openssl engine" utility can be useful for this sort
    182     of thing. For example the above code excerpt would achieve much the
    183     same result as;
    184 
    185        openssl engine dynamic \
    186                  -pre SO_PATH:/lib/libfoo.so \
    187                  -pre ID:foo \
    188                  -pre LOAD \
    189                  -pre "CMD_FOO:some input data"
    190 
    191     Or to simply see the list of commands supported by the "foo" ENGINE;
    192 
    193        openssl engine -vvvv dynamic \
    194                  -pre SO_PATH:/lib/libfoo.so \
    195                  -pre ID:foo \
    196                  -pre LOAD
    197 
    198     Applications that support the ENGINE API and more specifically, the
    199     "control commands" mechanism, will provide some way for you to pass
    200     such commands through to ENGINEs. As such, you would select "dynamic"
    201     as the ENGINE to use, and the parameters/commands you pass would
    202     control the *actual* ENGINE used. Each command is actually a name-value
    203     pair and the value can sometimes be omitted (eg. the "LOAD" command).
    204     Whilst the syntax demonstrated in "openssl engine" uses a colon to
    205     separate the command name from the value, applications may provide
    206     their own syntax for making that separation (eg. a win32 registry
    207     key-value pair may be used by some applications). The reason for the
    208     "-pre" syntax in the "openssl engine" utility is that some commands
    209     might be issued to an ENGINE *after* it has been initialised for use.
    210     Eg. if an ENGINE implementation requires a smart-card to be inserted
    211     during initialisation (or a PIN to be typed, or whatever), there may be
    212     a control command you can issue afterwards to "forget" the smart-card
    213     so that additional initialisation is no longer possible. In
    214     applications such as web-servers, where potentially volatile code may
    215     run on the same host system, this may provide some arguable security
    216     value. In such a case, the command would be passed to the ENGINE after
    217     it has been initialised for use, and so the "-post" switch would be
    218     used instead. Applications may provide a different syntax for
    219     supporting this distinction, and some may simply not provide it at all
    220     ("-pre" is almost always what you're after, in reality).
    221 
    222   How do I build a "dynamic" ENGINE?
    223   ----------------------------------
    224     This question is trickier - currently OpenSSL bundles various ENGINE
    225     implementations that are statically built in, and any application that
    226     calls the "ENGINE_load_builtin_engines()" function will automatically
    227     have all such ENGINEs available (and occupying memory). Applications
    228     that don't call that function have no ENGINEs available like that and
    229     would have to use "dynamic" to load any such ENGINE - but on the other
    230     hand such applications would only have the memory footprint of any
    231     ENGINEs explicitly loaded using user/admin provided control commands.
    232     The main advantage of not statically linking ENGINEs and only using
    233     "dynamic" for hardware support is that any installation using no
    234     "external" ENGINE suffers no unnecessary memory footprint from unused
    235     ENGINEs. Likewise, installations that do require an ENGINE incur the
    236     overheads from only *that* ENGINE once it has been loaded.
    237 
    238     Sounds good? Maybe, but currently building an ENGINE implementation as
    239     a shared-library that can be loaded by "dynamic" isn't automated in
    240     OpenSSL's build process. It can be done manually quite easily however.
    241     Such a shared-library can either be built with any OpenSSL code it
    242     needs statically linked in, or it can link dynamically against OpenSSL
    243     if OpenSSL itself is built as a shared library. The instructions are
    244     the same in each case, but in the former (statically linked any
    245     dependencies on OpenSSL) you must ensure OpenSSL is built with
    246     position-independent code ("PIC"). The default OpenSSL compilation may
    247     already specify the relevant flags to do this, but you should consult
    248     with your compiler documentation if you are in any doubt.
    249 
    250     This example will show building the "atalla" ENGINE in the
    251     crypto/engine/ directory as a shared-library for use via the "dynamic"
    252     ENGINE.
    253     1) "cd" to the crypto/engine/ directory of a pre-compiled OpenSSL
    254        source tree.
    255     2) Recompile at least one source file so you can see all the compiler
    256        flags (and syntax) being used to build normally. Eg;
    257            touch hw_atalla.c ; make
    258        will rebuild "hw_atalla.o" using all such flags.
    259     3) Manually enter the same compilation line to compile the
    260        "hw_atalla.c" file but with the following two changes;
    261          (a) add "-DENGINE_DYNAMIC_SUPPORT" to the command line switches,
    262 	 (b) change the output file from "hw_atalla.o" to something new,
    263              eg. "tmp_atalla.o"
    264     4) Link "tmp_atalla.o" into a shared-library using the top-level
    265        OpenSSL libraries to resolve any dependencies. The syntax for doing
    266        this depends heavily on your system/compiler and is a nightmare
    267        known well to anyone who has worked with shared-library portability
    268        before. 'gcc' on Linux, for example, would use the following syntax;
    269           gcc -shared -o dyn_atalla.so tmp_atalla.o -L../.. -lcrypto
    270     5) Test your shared library using "openssl engine" as explained in the
    271        previous section. Eg. from the top-level directory, you might try;
    272           apps/openssl engine -vvvv dynamic \
    273               -pre SO_PATH:./crypto/engine/dyn_atalla.so -pre LOAD
    274        If the shared-library loads successfully, you will see both "-pre"
    275        commands marked as "SUCCESS" and the list of control commands
    276        displayed (because of "-vvvv") will be the control commands for the
    277        *atalla* ENGINE (ie. *not* the 'dynamic' ENGINE). You can also add
    278        the "-t" switch to the utility if you want it to try and initialise
    279        the atalla ENGINE for use to test any possible hardware/driver
    280        issues.
    281 
    282   PROBLEMS
    283   ========
    284 
    285   It seems like the ENGINE part doesn't work too well with CryptoSwift on Win32.
    286   A quick test done right before the release showed that trying "openssl speed
    287   -engine cswift" generated errors. If the DSO gets enabled, an attempt is made
    288   to write at memory address 0x00000002.

      6 The version of OpenSSL found in this directory was created by taking the
      7 stock version of OpenSSL 0.9.8a from www.openssl.org and modifying some of
      8 the files to conform to Sun standards.  
      9 
     10 This work is based on previous work done on stock version of OpenSSL 0.9.7d
     11 shipped with Solaris 10.

     70 ===============================================
     71 The files differ from the original distribution
     72 ===============================================
     73 
     74 The following files are different from the OpenSSL 0.9.8a release.
     75 
     76 1. This header file is generated by Configure.  We combined four versions of 
     77    this file generated by four runs of Configure.
     78 
     79 	crypto/opensslconf.h
     80 
     81 2. Solaris OpenSSL supports PKCS#11 engine.
     82    This code may go back to the open-source community in the future.
     83 
     84    The following files were created.
     85 
     86 	crypto/engine/hw_pk11_err.h
     87 	crypto/engine/hw_pk11.c
     88 	crypto/engine/hw_pk11_err.c
     89 	crypto/engine/hw_pk11_pub.c
     90 
     91    The following files were modified.
     92 
     93 	crypto/engine/engine.h
     94 
     95 3. These files were modified to load the PKCS#11 engine.
     96    Added code is surrounded by "#ifdef SOLARIS_OPENSSL".
     97 
     98 	crypto/engine/eng_cnf.c
     99 	crypto/engine/hw_pk11.c
    100 
    101 
    102 4. We have a special case where OpenSSL is used by the "wanboot" binary
    103    program, that is run to boot the wanboot client.
    104    The following files are modified for this purpose.  Added code is 
    105    surrounded by "#ifdef _BOOT".
    106 
    107 	crypto/opensslconf.h
    108 	crypto/err/err_all.c
    109 	crypto/evp/evp_key.c
    110 	crypto/rand/rand_unix.c
    111 	crypto/rand/randfile.c
    112 	crypto/x509v3/v3_utl.c
    113 	e_os.h
    114 
    115 
    116 5. The configuration file was modified to ship with Solaris defaults.
    117 
    118 	$SRC/cmd/openssl/openssl.cnf
    119 	(Note: apps/openssl.cnf is unused.)
    120 
    121 
    122 6. Two files were added for a clean ON build even though the majority
    123    if OpenSSL code itself is not subject to lint checks (with the exception
    124    of crypto/engine/hw_pk11*.[ch] files).
    125 
    126 	crypto/llib-lcrypto
    127 	ssl/llib-lssl
    128 
    129 7. OpenSSL version string was modified. Due to the fact that we don't upgrade
    130    OpenSSL frequently we are forced to patch the currently shipped version. The
    131    problem with this aproach is that normally, every security vulnerability fix
    132    triggers a new release of OpenSSL so people can easily check whether their
    133    currently installed version is vulnerable or not. That is not possible with a
    134    patched older version. So, we decided to put the security bug tags into the
    135    version string, like this:
    136 
    137    OpenSSL 0.9.8a 11 Oct 2005 (+ security fixes for: CAN-2005-2969 CVE-2006-3738
    138    CVE-2006-4343 CVE-2007-3108 CVE-2007-5135 CVE-2008-5077)
    139 
    140    Note that actually it's all on the same line because we want to avoid
    141    problems with Configure scripts that might rely on the fact that the original
    142    OpenSSL version string consists of one line only.
    143 
    144    Be aware that the version string is not considered a stable interface and
    145    that all security vulnerability reports are available via SunAlert
    146    notifications.
    147 
    148 8. And, finally, this file was added.
