At least in OpenSSL (and likely the corresponding GnuTLS function,
but I have not looked) X509_digest() function takes a digest
algorithm parameter. There is not reason to not offer the user
a choice of algorithm.
Postfix also makes the public key (SPKI) digest available for access
checks (same digest algorithm).
