500 tests with various transactions and scripts, verifying that calcSignatureHash generates the expected hash in each case. This requires changing SigHashType to uint32; that won't affect the standard use-cases, but will make calcSignatureHash behave more like the Core counterpart for non-standard SigHashType settings, like those in some of these tests. |

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 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
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
