HashAlgorithm Property

The hash algorithm used for hash computation.

Syntax

int GetHashAlgorithm();
int SetHashAlgorithm(int iHashAlgorithm);

Possible Values

EHA_SHA1(0), 
EHA_SHA224(1),
EHA_SHA256(2),
EHA_SHA384(3),
EHA_SHA512(4),
EHA_MD2(5),
EHA_MD4(6),
EHA_MD5(7),
EHA_MD5SHA1(8),
EHA_RIPEMD160(9)

Default Value

2

Remarks

This property specifies the hash algorithm used for hash computation. This is only applicable when calling Sign or VerifySignature and KeyAlgorithm specifies a ECDSA key (secp256r1, secp384r1, or secp521r1. Possible values are:

0 (ehaSHA1) SHA-1
1 (ehaSHA224) SHA-224
2 (ehaSHA256 - default) SHA-256
3 (ehaSHA384) SHA-384
4 (ehaSHA512) SHA-512
5 (ehaMD2) MD2
6 (ehaMD4) MD4
7 (ehaMD5) MD5
8 (ehaMD5SHA1) MD5SHA-1
9 (ehaRIPEMD160) RIPEMD-160

When KeyAlgorithm specified an EdDSA key this setting is not applicable as the hash algorithm is defined by the specification as SHA-512 for ed25519 and SHAKE-256 for ed448.
