This commit adds an example test file so it integrates nicely with Go's example tooling. This allows the example output to be tested as a part of running the normal Go tests to help ensure it doesn't get out of date with the code. It is also nice to have the examples in one place rather than repeating it in doc.go and README.md. Links and information about the examples have been included in README.md in place of the examples and doc.go has been updated accordingly.

|
|
|
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 Conformal original is licensed under the
|
|
liberal ISC license.
|
|
|
|
This package is one of the core packages from btcd, an alternative full-node
|
|
implementation of bitcoin which is under active development by Conformal.
|
|
Although it was primarily written for btcd, this package has intentionally been
|
|
designed so it can be used as a standalone package for any projects needing to
|
|
use secp256k1 elliptic curve cryptography.

## Documentation
|
|
|
|
[]
|
|
(http://godoc.org/github.com/conformal/btcec)
|
|
|
|
Full `go doc` style documentation for the project can be viewed online without
|
|
installing this package by using the GoDoc site
|
|
[here](http://godoc.org/github.com/conformal/btcec).
|
|
|
|
You can also view the documentation locally once the package is installed with
|
|
the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
|
|
http://localhost:6060/pkg/github.com/conformal/btcec
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
$ go get github.com/conformal/btcec
|
|
```
|
|
|
|
## Examples
|
|
|
|
* [Sign Message]
|
|
(http://godoc.org/github.com/conformal/btcec#example-package--SignMessage)
|
|
Demonstrates signing a message with a secp256k1 private key that is first
|
|
parsed form raw bytes and serializing the generated signature.
|
|
|
|
* [Verify Signature]
|
|
(http://godoc.org/github.com/conformal/btcec#example-package--verifySignature)
|
|
Demonstrates verifying a secp256k1 signature against a public key that is
|
|
first parsed from raw bytes. The signature is also parsed from raw bytes.
|
|
|
|
## GPG Verification Key
|
|
|
|
All official release tags are signed by Conformal so users can ensure the code
|
|
has not been tampered with and is coming from Conformal. To verify the
|
|
signature perform the following:
|
|
|
|
- Download the public key from the Conformal website at
|
|
https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt
|
|
|
|
- Import the public key into your GPG keyring:
|
|
```bash
|
|
gpg --import GIT-GPG-KEY-conformal.txt
|
|
```
|
|
|
|
- Verify the release tag with the following command where `TAG_NAME` is a
|
|
placeholder for the specific tag:
|
|
```bash
|
|
git tag -v TAG_NAME
|
|
```
|
