All Implemented Interfaces:

CipherParameters

public class BLSPrivateKeyParameters
extends BLSKeyParameters

Private-key parameters for a BLS signature scheme. The underlying secret is an integer in [1, r - 1], where r is the suite's G1 / G2 subgroup order.

                               java.math.BigInteger sk)

Method Detail

getSecret

public java.math.BigInteger getSecret()

Returns:

the BLS secret scalar.

getEncoded

public byte[] getEncoded()

Returns:

the canonical 32-byte big-endian encoding of the secret scalar, matching the sk_to_lebytes/os2ip convention used by draft-irtf-cfrg-bls-signature KeyGen.
