This modifies the PrivateKey type to be opaque and updates the internal implementation of it to use the new ModNScalar type instead of a big.Int. It also modifies NewPrivateKey to accept the new ModNScalar type instead of a big.Int and improves the PrivKeyFromBytes comment to explicitly call out the semantics that realistically already existed when using the value in calculations. It is also worth noting that there are still a couple of internal conversions to big.Int when dealing with signatures that are required since that code still relies on them for now. The goal is to eventually update them to use the more efficient specialized types and this change help facilitate that process. |

txscript
Package txscript implements the Decred 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 Decred transaction scripts.
Decred Scripts
Decred provides a stack-based, FORTH-like language for the scripts in the Decred transactions. This language is not turing complete although it is still fairly powerful.
Installation and Updating
$ go get -u github.com/decred/dcrd/txscript
Examples
-
Standard Pay-to-pubkey-hash Script Demonstrates creating a script which pays to a Decred address. It also prints the created script hex and uses the DisasmString function to display the disassembled script.
-
Extracting Details from Standard Scripts Demonstrates extracting information from a standard public key script.
-
Manually Signing a Transaction Output Demonstrates manually creating and signing a redeem transaction.
-
Counting Opcodes in Scripts Demonstrates creating a script tokenizer instance and using it to count the number of opcodes a script contains.
