I need to hash strings to a shorter checksum on a "BigData" heavy-throughput project. The common choice would be SHA, probably SHA1 for speed reasons or CRC32 as the checksums will be used internally only and don't need to be cryptographic secure. A StackExchange answer suggested MurmurHash3, but how does it play with Perl?

CRC32 vs. CRC32B
Someone asked me about a CRC32B checksum today. No problem, there is CPAN and a common checksum like CRC should be very easy, there must be a module (or two or three or so) on CPAN, task done, next one. Stop. There are two modules for CRC32: Digest::CRC32 and String::CRC32 but really nothing for CRC32B.
