Cipher

Cipher algorithms in Golang

---

Getting Started

Prerequisite

Create .env file in your root directory and add below variables

• CIPHER_PASSWORD
• CIPHER_SALT

Note: Rotate password/salt pair regularly

When encryption runs more than 2^32 times, Nonce is at the risk of a repeat

Installing

go get it (pun intended 😸)

go get github.com/junekimdev/cipher

Usage

package main

import (
  "log"

  "github.com/junekimdev/cipher"
)


func main() {
  // text to encrypt
  encrypted, err := cipher.Encrypt(text)

  // encrypted text to decrypt
  decrypted, err := cipher.Decrypt(string(encrypted))
  ////---- decrypted == text

  // a file to encrypt
  cipher.EncryptFile(plainTextFile1, encryptedFile)

  // encrypted text to decrypt
  cipher.DecryptFile(encryptedFile, plainTextFile2)
  ////---- plainTextFile1 == plainTextFile2
}
