The crypto package

Notice: The public API is not stable and backward compatibility is currently not guaranteed. This code should currently NOT used in productive environments!

Introduction

The crypto package implements some additional cryptographic functionality, currently not supported by the standard or additional golang packages.
This repository should not replace or somehow compete with the golang crypto packages. Rather, this package should supplement the official and additional golang cryptographic.

Currently implemented:

Aim

The aim of this project / repository is a powerful, flexible and easy to use cryptographic library, which can be easily integrated into Go applications.

Installation

Install in your GOPATH: go get -u github.com/enceve/crypto
Install Dependencies: go get -u golang.org/x/crypto

Contribute

First of all: Contributions are welcome!

If you have an idea or found a bug - please raise an issue. If you want to add functionality - as usual on github send a pull request.

Functions

func XOR

func XOR(dst, src, with []byte) int

XOR xors the bytes in src and with and writes the result to dst. The destination is assumed to have enough space. Returns the number of bytes xor'd.

Types

type AuthenticationError

type AuthenticationError struct{}

A AuthenticationError indicates, that an authentication process failed. E.g. the message authentication of a AEAD cipher.

func (AuthenticationError) Error

func (a AuthenticationError) Error() string

type KeySizeError

type KeySizeError int

A KeySizeError indicates, that the size of a given key does not match the expected size.

func (KeySizeError) Error

func (k KeySizeError) Error() string

type NonceSizeError

type NonceSizeError int

A NonceSizeError indicates, that the size of a given nonce does not match the expected size.

func (NonceSizeError) Error

func (n NonceSizeError) Error() string
