secp256k1
Package dcrec implements elliptic curve cryptography needed for working with Decred (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 dcrec was originally based on work from ThePiachu which is licensed under the same terms as Go, but it has signficantly diverged since then. The decred developers original is licensed under the liberal ISC license.
Although this package was primarily written for dcrd, 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 get -u github.com/decred/dcrd/dcrec
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. -
Encryption
Demonstrates encrypting a message for a public key that is first parsed from raw bytes, then decrypting it using the corresponding private key. -
Decryption
Demonstrates decrypting a message using a private key that is first parsed from raw bytes.
License
Package dcrec is licensed under the copyfree ISC License except for dcrec.go and dcrec_test.go which is under the same license as Go.
