The Digest family is probably what you want; Digest::SHA1. The algorithms are supported in all the DBs too so it's easy to validate/store. 

perl -MDigest::SHA1 -le 'print Digest::SHA1::sha1_hex(shift)' s3cr3t

perl -MDigest::SHA1 -le 'print Digest::SHA1::sha1_hex(shift)' s3cr3ts

Be aware that there are efforts to generate look-up tables for these so you still need to enforce prohibitions against the usual problematic/weak passwords (dictionary words, sequences, etc). The sha for "password" for example, 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8, has 681 hits on Google. And 682 come reindex time. :)
