Make hashing functions backwards compatible with mixlib-authentication 1.3

I had assumed that those functions were only used internally to
mixlib-authentication. It seems that oc-chef-pedant tests use
these functions. This patch makes the function backwards compatible
by defaulting to using SHA1 for the digester if one is not supplied
