Documentation

Overview

Package signature provides simple methods to create and verify signatures in PEM format.

Functions

func GenerateKeys

func GenerateKeys() (privKey []byte, pubKey []byte, err error)

GenerateKeys returns a new key pair, with the private and public key encoded in PEM format.

func Sign

func Sign(privKeyPEM []byte, data io.Reader) ([]byte, error)

Sign computes the hash of data and signs it with the private key, returning a signature in PEM format.

func Verify

func Verify(pubKeyPEM []byte, signature []byte, data io.Reader) error

Verify computes the hash of data and compares it to the signature using the given public key. Returns nil if the signature is correct.
