--+---[Hash_Algorithm_Id]--------------------------------------------
--| Enumerated type that identifies the different message digest
--| algorithms implemented in the ACF. Possible values are:
--|
--| MD2 Identifier of the RSA MD2 Message Digest
--| algorithm. It produces 128-bit message
--| digests.
--| MD4 Identifier of the RSA MD4 Message Digest
--| algorithm. It produces 128-bit message
--| digests.
--| MD5 Identifier of the RSA MD5 Message Digest
--| algorithm. It produces 128-bit message
--| digests.
--| SHA1 Identifier of the SHS SHA 1 Message Digest
--| algorithm. It produces 160-bit message
--| digests.
--| RIPEMD_128 Identifier of the RIPEMD-128 Message
--| Digest algorithm. It produces 128-bit
--| message digests.
--| RIPEMD_160 Identifier of the RIPEMD-160 Message
--| Digest algorithm. It produces 160-bit
--| message digests.
--| TIGER Identifier of the TIGER Message Digest
--| algorithm. It produces 192-bit message
--| digests.
--| HAVAL Identifier of the HAVAL message digest
--| algorithm. It can produce 128, 160, 192
--| 224, or 256-bit message digests.
