This is a simple and naïve Go implementation of the standard 64-byte Schnorr signature scheme over the elliptic curve secp256k1 defined by BIP340. It only implements simple signing and verifying.
The current version passes all test vectors provided with the BIP (but the author does not give any guarantees that the algorithm is implemented correctly or safely).
Install using:
go get -u github.com/fiatjaf/bip340In your code:
import "github.com/fiatjaf/bip340"
signature, err := bip340.Sign(privateKey, message)
result, err := bip340.Verify(publicKey, message, signature)
