Abstract Value Members

  1. abstract def add(pk1: ECPublicKey, pk2: ECPublicKey): ECPublicKey

    Adds two public keys together, failing if the sum is 0x00 (the point at infinity).

  2. abstract val cryptoContext: CryptoContext
  3. abstract def decodePoint(bytes: ByteVector): SecpPoint
  4. abstract def freshPrivateKey: ECPrivateKey

    Generates a 32 byte private key

  10. abstract def randomBytes(n: Int): ByteVector
  11. abstract def recoverPublicKey(signature: ECDigitalSignature, message: ByteVector): (ECPublicKey, ECPublicKey)

    Recover public keys from a signature and the message that was signed.

    Recover public keys from a signature and the message that was signed. This method will return 2 public keys, and the signature can be verified with both, but only one of them matches that private key that was used to generate the signature.

    signature

    message

    message that was signed

    returns

    a (pub1, pub2) tuple where pub1 and pub2 are candidates public keys. If you have the recovery id then use pub1 if the recovery id is even and pub2 if it is odd
