        # go-mcrypt

[![Build Status](https://travis-ci.org/mfpierre/go-mcrypt.svg?branch=master)](https://travis-ci.org/mfpierre/go-mcrypt)

Go bindings for mcrypt library.

Should be compatible with most algo/modes supported by libmcrypt.

## Requirements

 * libmcrypt (http://mcrypt.sourceforge.net/)

## Usage

```go

package main

import (

	"fmt"

	mcrypt "github.com/mfpierre/go-mcrypt"

)

func main() {

	key := []byte("here is a random key of 32 bytes")

	plaintext := []byte("here is what you want to encrypt")

	iv := make([]byte, 16)

	// using CAST-256 in ECB mode

	encrypted, _ := mcrypt.Encrypt(key, iv, plaintext, "cast-256", "ecb")

	decrypted, _ := mcrypt.Decrypt(key, iv, encrypted, "cast-256", "ecb")

	fmt.Println(encrypted)

	fmt.Println(decrypted)

}

```

Below a reminder of IV & Key size that you can use depending on algo/mode settings
