PROV_DSS_DH Provider Algorithms

The following table lists the algorithms supported by the Microsoft Base DSS and Diffie-Hellman Cryptographic Provider.

Algorithm IDDescriptionComments
CALG_MD5MD5 hashing algorithm.Provided only for hashing.
CALG_SHASHA hashing algorithm.Must be used for DSS signatures.
CALG_SHA1Same as CALG_SHA.No comment.
CALG_DSS_SIGNDSS public/private key signature algorithm.Key length: can be set, 512 bits to 1,024 bits in 64 bit increments.

Default key length: 1,024 bits.

CALG_DH_SFStore and Forward D-H key exchange.Key length: can be set, 384 bits to 512 bits in 8 bit increments.

Default key length: 512 bits.

CALG_DH_EPHEMEphemeral D-H key exchange.Key length: can be set, 384 bits to 512 bits in 8 bit increments.

Default key length: 512 bits.

CALG_CYLINK_MEKA 40-bit variant of a DES key.Key Length: 40 bits.
