HashAlgorithm Property
The hash algorithm used for hash computation.
Syntax
property HashAlgorithm: TipcECCHashAlgorithms read get_HashAlgorithm write set_HashAlgorithm;
TipcECCHashAlgorithms = ( ehaSHA1, ehaSHA224, ehaSHA256, ehaSHA384, ehaSHA512, ehaMD2, ehaMD4, ehaMD5, ehaMD5SHA1, ehaRIPEMD160 );
Default Value
ehaSHA256
Remarks
This property specifies the hash algorithm used for hash computation. This is only applicable when calling Sign or VerifySignature and Algorithm 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 Algorithm 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.
