perl-Module-Signature

*Module::Signature* adds cryptographic authentications to CPAN distributions, via the special _SIGNATURE_ file. If you are a module user, all you have to do is to remember to run 'cpansign -v' (or just 'cpansign') before issuing 'perl Makefile.PL' or 'perl Build.PL'; that will ensure the distribution has not been tampered with. Module authors can easily add the _SIGNATURE_ file to the distribution tarball; see NOTES below for how to do it as part of 'make dist'. If you _really_ want to sign a distribution manually, simply add 'SIGNATURE' to _MANIFEST_, then type 'cpansign -s' immediately before 'make dist'. Be sure to delete the _SIGNATURE_ file afterwards. Please also see NOTES about _MANIFEST.SKIP_ issues, especially if you are using *Module::Build* or writing your own _MANIFEST.SKIP_. Signatures made with Module::Signature prior to version 0.82 used the SHA1 algorithm by default. SHA1 is now considered broken, and therefore module authors are strongly encouraged to regenerate their _SIGNATURE_ files. Users verifying old SHA1 signature files will receive a warning.
