BLSPrivateKeyParameters (Bouncy Castle Library 1.85 API Specification)

java.lang.Object
- org.bouncycastle.crypto.params.AsymmetricKeyParameter
- - org.bouncycastle.crypto.params.BLSKeyParameters
  - - org.bouncycastle.crypto.params.BLSPrivateKeyParameters

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.

- 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.
