}

Example 2 with MPInt

use of co.krypt.krypton.pgp.packet.MPInt in project krypton-android by kryptco.

the class EdSSHKeyPair method pgpSign.

@Override
public Signature pgpSign(HashAlgorithm hash, byte[] data) throws PGPException, NoSuchAlgorithmException, CryptoException, SignatureException, NoSuchProviderException, InvalidKeyException, InvalidKeySpecException {
    byte[] signatureBytes = signDigest(hash.digest().digest(data));
    if (signatureBytes.length != 64) {
        throw new SodiumException("unexpected signature length");
    }
    byte[] r = Arrays.copyOfRange(signatureBytes, 0, 32);
    byte[] s = Arrays.copyOfRange(signatureBytes, 32, 64);
    return new Ed25519Signature(new MPInt(r), new MPInt(s));
