SignerKeyAlgorithm Property

This property holds the algorithm associated with the key.

Syntax

int GetSignerKeyAlgorithm();
int SetSignerKeyAlgorithm(int iSignerKeyAlgorithm);

Possible Values

EA_SECP_256R_1(0), 
EA_SECP_384R_1(1), 
EA_SECP_521R_1(2), 
EA_ED_25519(3), 
EA_ED_448(4), 
EA_X25519(5), 
EA_X448(6), 
EA_SECP_160K_1(7), 
EA_SECP_192K_1(8), 
EA_SECP_224K_1(9), 
EA_SECP_256K_1(10)

Default Value

0

Remarks

This property holds the algorithm associated with the key. Possible values are:

• 0 (eaSecp256r1)
• 1 (eaSecp384r1)
• 2 (eaSecp521r1)
• 3 (eaEd25519)
• 4 (eaEd448)
• 5 (eaX25519)
• 6 (eaX448)
• 7 (eaSecp160k1)
• 8 (eaSecp192k1)
• 9 (eaSecp224k1)
• 10 (eaSecp256k1)

When assigning a key using the PEM formatted SignerKeyPrivateKey and SignerKeyPublicKey the SignerKeyAlgorithm property will be automatically updated with the key algorithm.

When assigning a key using the raw key parameters (SignerKeyK, SignerKeyRx, and SignerKeyRy for NIST or SignerKeyXPk, and SignerKeyXSk for Curve25519/Curve448) the SignerKeyAlgorithm property must be set manually to the key algorithm.
