[However, none of that term is relevant at this point in time. All of these restrictively li-
cenced software components which he talks about have been removed from OpenSSH,
i.e.,
– RSA is no longer included, found in the OpenSSL library
– IDEA is no longer included, its use is deprecated
– DES is now external, in the OpenSSL library
– GMP is no longer used, and instead we call BN code from OpenSSL
– Zlib is now external, in a library
– The make-ssh-known-hosts script is no longer included
– TSS has been removed
– MD5 is now external, in the OpenSSL library
– RC4 support has been replaced with ARC4 support from OpenSSL
– Blowfish is now external, in the OpenSSL library
