Interface EcdsaSignature

All Known Implementing Classes:
EcdsaSignatureImpl
public interface EcdsaSignature
An secp256k1 ECDSA signature.

  • Method Details

    • r

      SecpScalar r()
      Get scalar R
      Returns:
      R

    • s

      SecpScalar s()
      Get scalar S
      Returns:
      S

    • serializeCompact

      byte[] serializeCompact()
      Serialize as a Bitcoin compact signature. A compact signature is the two signature component scalars (known as r and s) serialized in-order as binary data in big-endian format.
      Returns:
      a Bitcoin compact signature

    • hasLowR

      boolean hasLowR()
      Is this signature a "low R" signature. In other words: In a 256-bit big-endian representation of R, the high-bit is zero.
      Returns:
      true if this signature has a low R value.
