Class FalconPrivateKeyParameters

All Implemented Interfaces:
CipherParameters

public class FalconPrivateKeyParameters extends FalconKeyParameters
  • Constructor Details

    • FalconPrivateKeyParameters

      public FalconPrivateKeyParameters(FalconParameters parameters, byte[] f, byte[] g, byte[] F, byte[] pk_encoded)
  • Method Details

    • getEncoded

      public byte[] getEncoded()
    • getPublicKey

      public byte[] getPublicKey()
      Return the encoded public key for this private key.

      When this instance still carries the encoded public key (the usual case for a freshly generated key) that encoding is returned directly. When it does not — e.g. the key was reconstructed from only its private encoding (f ‖ g ‖ F), with no public key bytes retained — the public key h is recomputed from the private polynomials (h = g * f-1 mod (q, xn+1)) (github #2297).

    • getPublicKeyParameters

      public FalconPublicKeyParameters getPublicKeyParameters()
      Return the matching FalconPublicKeyParameters for this private key, mirroring MLDSAPrivateKeyParameters.getPublicKeyParameters(). Lets wallet / HSM code recover the public key from a stored private key without re-running keygen; see getPublicKey() for how the key is recovered when no public key bytes were retained (github #2297).
    • getSpolyf

      public byte[] getSpolyf()
    • getG

      public byte[] getG()
    • getSpolyF

      public byte[] getSpolyF()
