@izzius94/crypter

The crypter library makes easy to share encrypted data with a Laravel project.

Features

• Genaration of encryption keys from command line
• Encryption of strings
• Decryption of strings

Supported algorithms

• aes-256-cbc (default)
• aes-128-cbc
• aes-256-gcm
• aes-128-gcm

Missing features

Currently serialization and deserialization is not supported.

To mitigate this use php-serialize library.

Usage

Full documentation here

Creation of encryption key

npx @izzius94/crypter

This command will output a new encryption key in yor console. This command accept the algorithm to use as a parameter. If the algorithm is not supported it will exit with an error

Encrypt/decrypt strings

To encrypt/decrypt strings use encrypt and decrypt methods passing the encryption key as the second parameter.

import { encrypt, decrypt } from '@izzius94/crypter'

const key = readKey('8U6GU1Tp1/0Jb7/1BRCxpzQubzBKfs1Sm8V8Wtce4+U==')
const original = 'my-string'
const crypted = crypter.encrypt(original, key)
const decrypted = crypter.decrypt(crypted, key)

console.log(original === decrypted)

To use a different algorithm pass it as the third parameter to the methods encrypt and decrypt.

Using the Crypter class to encrypt and decrypt a string

Sometimes you will need to use the same key accross multiple classes. To help you do this you can use the class Crypter to share the same encryption key.

import { Crypter, readKey } from '@izzius94/crypter'

const crypter = new Crypter(readKey('TkIRuk6C70E2ExHunuX+wg3CwX+kcgkbg59Yhwiqi7s='))
const original = 'my-string'
const crypted = crypter.encrypt(original)
const decrypted = crypter.decrypt(crypted)

// Will output true
console.log(original === decrypted)

To use a different algorithm pass it as second parameter to the constructor of the class Crypter
