Dave Collins c701477eaf txscript: Slight crypto hash optimizations. This commit very slightly optimizes the cryptographic hashing performed by the script opcodes by calling the hash sum routines directly (for those that support it) rather than allocating a new generic hash.Hash hasher instance for them.		2015-04-27 12:32:32 -05:00

txscript

[] (https://travis-ci.org/btcsuite/btcd)

Package txscript implements the bitcoin transaction script language. There is a comprehensive test suite. Package txscript is licensed under the liberal ISC license.

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 langauge 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

Documentation

[] (http://godoc.org/github.com/btcsuite/btcd/txscript)

Full go doc style documentation for the project can be viewed online without installing this package by using the GoDoc site here.

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/btcsuite/btcd/txscript

Installation

$ go get 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 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:
```
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
```
