This function provides a general interface to a variety of secure
hashing algorithms. As well as the MD5 algorithm, it supports SHA-1,
SHA-2, SHA-224, SHA-256, SHA-384 and SHA-512. The argument
@var{algorithm} is a symbol stating which hash to compute. The
arguments @var{object}, @var{start}, and @var{end} are as for the
@code{md5} function. If the optional argument @var{binary} is
non-@code{nil}, returns a string in binary form.

** New primitive `secure-hash' that supports many secure hash algorithms:
md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library
sha1.el has been removed. The `sha1' feature is provided by default.
