override def verifyEcdsaSecp256k1Signature(pk: ByteString, msg: ByteString, sig: ByteString): Boolean

Verify an ECDSA signature made using the SECP256k1 curve.

Verify an ECDSA signature made using the SECP256k1 curve.

Value parameters

msg

Message (32 bytes)

pk

Public key (33 bytes)

sig

Signature (64 bytes)

Attributes

Note

There are additional well-formation requirements for the arguments beyond their length:

  • The first byte of the public key must correspond to the sign of the y coordinate: this is 0x02 if y is even, and 0x03 otherwise.
  • The remaining bytes of the public key must correspond to the x coordinate, as a big-endian integer.
  • The first 32 bytes of the signature must correspond to the big-endian integer representation of r.
  • The last 32 bytes of the signature must correspond to the big-endian integer representation of s. While this primitive accepts a hash, any caller should only pass it hashes that they computed themselves: specifically, they should receive the message from a sender and hash it, rather than receiving the hash from said sender. Failure to do so can be dangerous. Other than length, we make no requirements of what hash gets used.

There are additional well-formation requirements for the arguments beyond their length. Throughout, we refer to co-ordinates of the point R.

  • The bytes of the public key must correspond to the x coordinate, as a big-endian integer, as specified in BIP-340.
  • The first 32 bytes of the signature must correspond to the x coordinate, as a big-endian integer, as specified in BIP-340.
  • The last 32 bytes of the signature must correspond to the bytes of s, as a big-endian integer, as specified in BIP-340.
