This modifies the PrivateKey type to be defined as its own struct as opposed of in terms of an ecdsa.PrivateKey and updates the code and tests accordingly. It also removes the PrivKeyFromScalar and GenerateKey funcs while here since they are effectively duplicates of existing funcs that were added to satisfy the chainec interface which no longer exists. For now, it essentially keeps the same format with the exception of embedding the ecdsa.PublicKey, but being its own type will alllow for it to eventually be made opaque and thus provide greater optimizations. This is continued work towards making the internals of the package entirely independent of the crypto/elliptic and crypto/ecdsa stdlib interfaces. |

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.
