lightweight Crypt/Digest convenience API

 Crypt::Util provides an easy, intuitive and forgiving API for wielding
 crypto-fu.
 .
 The API is designed as a cascade, with rich features built using
 simpler ones. This means that the option processing is uniform
 throughout, and the behaviors are generally predictable.
 .
 Note that Crypt::Util doesn't do any crypto on its own, but delegates
 the actual work to the various other crypto modules on the CPAN.
 Crypt::Util merely wraps these modules, providing uniform parameters,
 and building on top of their polymorphism with higher level features.
