module Gem
# There is an incompatibility between the way Ruby 1.8.5 and 1.8.6
# handles digests. This DigestAdapter will take a pre-1.8.6 digest
# and adapt it to the 1.8.6 API.
#
# Note that only the digest and hexdigest methods are adapted,
# since these are the only functions used by Gems.
#
class DigestAdapter
# Initialize a digest adapter.

# Return a new digester. Since we are only implementing the stateless
# methods, we will return ourself as the instance.
