txscript

[] (https://travis-ci.org/btcsuite/btcd) ![ISC License] (http://img.shields.io/badge/license-ISC-blue.svg) [] (http://godoc.org/github.com/btcsuite/btcd/txscript)

Package txscript implements the bitcoin transaction script language. There is a comprehensive test suite.

This package has intentionally been designed so it can be used as a standalone package for any projects needing to use or validate bitcoin transaction scripts.

Bitcoin Scripts

Bitcoin provides a stack-based, FORTH-like language for the scripts in the bitcoin transactions. This language is not turing complete although it is still fairly powerful. A description of the language can be found at https://en.bitcoin.it/wiki/Script

Installation and Updating

$ go get -u github.com/btcsuite/btcd/txscript

Examples

[Standard Pay-to-pubkey-hash Script] (http://godoc.org/github.com/btcsuite/btcd/txscript#example-PayToAddrScript)
Demonstrates creating a script which pays to a bitcoin address. It also prints the created script hex and uses the DisasmString function to display the disassembled script.
[Extracting Details from Standard Scripts] (http://godoc.org/github.com/btcsuite/btcd/txscript#example-ExtractPkScriptAddrs)
Demonstrates extracting information from a standard public key script.
[Manually Signing a Transaction Output] (http://godoc.org/github.com/btcsuite/btcd/txscript#example-SignTxOutput)
Demonstrates manually creating and signing a redeem transaction.

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 the btcsuite developers. 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:
```
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:
```
git tag -v TAG_NAME
```
