This is Debian GNU/Linux's prepackaged version of Digest::HMAC. This is a perl library for implementing the HMAC mechanism described in RFC 2104. The RFC document has been removed from the tarball due to licensing issues. This package was put together by Michael Alan Dorman . Matthias Urlichs took over maintenance upon the release of version 1.01-3 . However, due to his heavy workload, he opted to put this package up for adoption. Zak B. Elep now maintains this package. The original sources should always be available from the Comprehensive Perl Archive Network (CPAN). Visit to find a CPAN site near you. The only change for the Debian package was the addition of the debian/ files. The Digest::HMAC copright is as follows: Copyright 1998-2001 Gisle Aas. Copyright 1998 Graham Barr.
