Crypt::Password::Util is a crypt password utilities. Its crypt($str) works like Perl's crypt(), but automatically choose the appropriate crypt type and random salt. Will first choose SSHA512 with 64-bit random salt. If not supported by system, fall back to MD5-CRYPT with 32-bit random salt. If that is not supported, fall back to CRYPT. Its crypt_type($str) returns crypt type, or undef if $str does not look like a crypted password. Currently known types: CRYPT (traditional DES crypt), MD5-CRYPT (including Apache variant), SSHA256 (salted SHA256), SSHA512 (salted SHA512), and PLAIN-MD5. See also Authen::Passphrase which recognizes more encodings (but currently not SSHA256 and SSHA512). WWW: http://search.cpan.org/dist/Crypt-Password-Util/
