IIRC, CRAM-MD5 doesn't protect against chosen plaintext attacks, or
something like that. It is recommended that people use DIGEST-MD5 instead.

It depends on the mechanisms, which are dynamically loaded at runtime.
DIGEST-MD5 doesn't need any external libraries. SRP requires OpensSSL's
libcrypto. Also, OTP and NTLM require libcrypto even though they don't
do protocol encryption.
