Hi all,

I'm currently performing a hash check for password verification. I'm generating an md5 hash or checking for plain text in pg_shadow. However, outside of these two "out-of-the-box" options, what if someone is using pg-crypto or any other PAM ? How can I differentiate between say md5 and pgcrypto ? I see the md5 is prefixed in hash in pg_shadow. I was wondering what other prefixes may exist, say for pgcrypto. If you have an examples of what a pgcrypto or any other PAM hash would look like (or what they would at least begin with), that would be great.

Thanks,
Frank
