     27     [However, none of that term is relevant at this point in time.  All of
     28     these restrictively licenced software components which he talks about
     29     have been removed from OpenSSH, ie.
     30 
     31      - RSA is no longer included, found in the OpenSSL library
     32      - IDEA is no longer included, it's use is depricated
     33      - DES is now external, in the OpenSSL library
     34      - GMP is no longer used, and instead we call BN code from OpenSSL
     35      - Zlib is now external, in a library
     36      - The make-ssh-known-hosts script is no longer included
     37      - TSS has been removed
     38      - MD5 is now external, in the OpenSSL library
     39      - RC4 support has been replaced with ARC4 support from OpenSSL
     40      - Blowfish is now external, in the OpenSSL library
