kripta-js

An simple implementation of a Symmetric(AES) and Asymmetric(RSA) encryption for humans.

Features

• Generate RSA keys like
• Encrypt/Decrypt messages, files, binaries on symmetric or asymmetric

How to use

• Install the lib

yarn add kripta-js
# or
npm install kripta-js

• To use the symmetric encryption (AES):

  • Schema :

    

  • Code :

    import {KriptaAES} from "kripta-js";
    
    const message = "secret-message"
    const secret_key = "secret-code-password"
    
    const k = KriptaAES()
    // to encrypt
    const encrypted_msg = k.encrypt(message, secret_key)
    
    // to decrypt
    console.log(k.decrypt(encrypted_msg1, secret_key).decode())
    // secret-message 

  • Some methods and their Inputs/Outputs

    function	params & types	return type
    encrypt	message(Buffer	str), secret_key(str)
    decrypt	encrypted_messsage(Buffer	str), secret_key(str)
    encryptFile	path_of_file(str), password(str)	str
    decryptFile	path_of_encrypted_file(str), password(str)	str

• To use an asymmetric encryption (RSA):

  • Schema :

    

  • Code example:

    import {KriptaRSA} from "kripta-js";
    
    const message = "secret-message"
    const pub_key = `-----BEGIN PUBLIC KEY-----
    ....
    -----END PUBLIC KEY-----`
    
    const k = KriptaRSA()
    k.setPublicKey(pub_key)
    // To encrypt a message
    const encrypted_msg = k.encrypt(k.getPublicKey(), message.encode())
    
    const priv_key = `-----BEGIN RSA PRIVATE KEY-----
    .....
    -----END RSA PRIVATE KEY-----`
    
    k.setPrivateKey(priv_key)
    // To decrypt
    console.log(k.decrypt(encrypted_msg).decode())
    // secret-message 

  • Some methods and their Inputs/Outputs

    function	params & types	return type
    encrypt	publicKey(str), message(str)	str
    setPublicKey	publicKey(str)	str
    setPrivateKey	privateKey(str)	str
    decrypt	encrypted_messsage(Buffer	str)
