Log:
Enable RC2 support with libgcrypt
The name "RC2" is not used by libgcrypt, instead it uses
"RFC2268_<keysize>". RFC2268_40 and RFC2268_128 are both documented,
though only RFC2268_40 is implemented right now.
As documented in RFC2246 (TLS 1.0), section 6.3.1 Export key generation
example, exportable ciphers (in this case, the
TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5 cipher) only use 40 bits of the
key_block, but the real key (final_{client,server}_write_key) used for
the actual algorithm (RC2) is still 16 bytes (128 bits). Therefore
RFC2268_128 is the correct name to use.
As libgcrypt 1.5.3 does not support the 128-bit keys, I have submitted a
patch for libgcrypt to support the larger 128-bit rc2 keys has been
submitted to gcrypt-devel@xxxxxxxxx (it sits in their mail queue as I am
not subscribed).
