This modifies the conversion of the output index from the JSON-based test data for valid and invalid transactions as well as the signature hash type for signature hash tests to first convert to a signed int and then to an unsigned int. This is necessary because the result of a direct conversion of a float to an unsigned int is implementation dependent and doesn't result in the expected value on all platforms. Also, while here, change the function names in the error prints to match the actual names. Fixes #600. |

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
