In this commit, we introduce an easier to use API for musig2 signing in the Session and Context structs. The Context struct represents a particular musig2 signing context which is defined by the set of signers. The struct can be serialized to disk as it contains no volatile information. A given context can be kept for each signer in the final set. The Session struct represents an ephemeral musig2 signing session. It handles nonce generation, key aggregation, nonce combination, signature combination, and final sig verification all in one API. The API also protects against nonce generation by not exposing nonces to the end user and also attempting to catch nonce re-use (assuming no process forking) across sessions. |

btcec
Package btcec implements elliptic curve cryptography needed for working with Bitcoin (secp256k1 only for now). It is designed so that it may be used with the standard crypto/ecdsa packages provided with go. A comprehensive suite of test is provided to ensure proper functionality. Package btcec was originally based on work from ThePiachu which is licensed under the same terms as Go, but it has signficantly diverged since then. The btcsuite developers original is licensed under the liberal ISC license.
Although this package was primarily written for btcd, it has intentionally been designed so it can be used as a standalone package for any projects needing to use secp256k1 elliptic curve cryptography.
Installation and Updating
$ go install -u -v github.com/btcsuite/btcd/btcec/v2
Examples
-
Sign Message
Demonstrates signing a message with a secp256k1 private key that is first parsed form raw bytes and serializing the generated signature. -
Verify Signature
Demonstrates verifying a secp256k1 signature against a public key that is first parsed from raw bytes. The signature is also parsed from raw bytes.
License
Package btcec is licensed under the copyfree ISC License except for btcec.go and btcec_test.go which is under the same license as Go.
