A package that provides simplified helper functions for using scrypt (128-bit salt, N=32768, r=8 and p=1) generated hash as a key to encrypt data with AES-256-GCM.

GoCrypt - A Golang Encryption Helper Package

maintained by: hkdb

SUMMARY:

Package 3dfosi/gocrypt provides simplified helper functions for using scrypt (128-bit salt, N=32768, r=8 and p=1) generated hash as a key to encrypt data with AES-256-GCM.

Common use cases include but are not limited to encrypting data at rest for applications and symetric encryption automation prior to transfering files to destination.

USAGE:

Import package:

import "github.com/3dfosi/gocrypt"

Example:

package main

import (
	"encoding/hex"
	"log"

	"github.com/3dfosi/gocrypt"
)

var passphrase = "SOME-CRAZY-LONG-PASSPHRASE"

func main() {

	// Encrypt Data
	encrypted_data, salt, err := gocrypt.Encrypt([]byte("Hello World"), passphrase)
	if err != nil {
		log.Println(err)
		return
	}
	log.Println("Encrypted DATA:", hex.EncodeToString(encrypted_data))
	log.Println("SALT:", hex.EncodeToString(salt))

	// Decrypt Data
	plaintext, err := gocrypt.Decrypt(encrypted_data, salt, passphrase)
	if err != nil {
		log.Println(err)
		return
	}
	log.Println("Plain Text:", string(plaintext))

}
