changes since 2.04:

   Release 2.06

   The sha1_transform() function did not check that it was actually
   passed any arguments.

   Complete self-contained documentation included (copied from
   Digest::MD5), since the Digest.pm manpage is not always available.

   Release 2.05

   Added missing cast to support C++ compilation.  Patch by Jan Dubois.

   Document that the sha1_base64 function and the b64digest method
   does not pad their result.
