2.1 Digest Procedures
=====================

The acceptable input objects for the digest procedures are
strings, input-ports, byte-vectors, or anything that can be
converted to a byte-vector. See message-digest
(http://www.call-with-current-continuation.org/eggs/message-digest.html)
for more information.

 -- procedure: sha1:digest
          (sha1:digest OBJECT)

     Returns the SHA1 checksum of `OBJECT' as a hex 					string.

 -- procedure: sha1:binary-digest
          (sha1:binary-digest OBJECT)

     Returns the SHA1 checksum of `OBJECT' as a string.

 -- procedure: sha1:primitive
          (sha1:primitive)

     Returns the SHA1 checksum primitive object.
