Usage(JavaScript)

Implementation:-

npm i @zozoto/encrypto

or For HTML

RSA

RSA Init

import Encrypto from '@zozoto/encrypto';
let encrypto = new Encrypto('RSA', 128);
//this generates public and private keys for e2ee, the default bitlength is 256
//keep the bitlength low if you are going to use it in web.

Get ZotPublicKey

let publicKeyString = encrypto.getSterilizedPublicKey();
//returns a base64 encoded public key which you can send to all other clients

//to convert above publicKeyString to ZotPublicKey use:
let pubKey = encrypto.deSterilizeZotPublicKey(publicKeyString);
// pass the public key string which you recieved from the client.
//another method to get the public key directly is:
let publicKey = encrypto.getZotPublicKey();
//returns a map with public exponent and modulus

RSA Encrypt

let val = "alo";
let base64encrypted = encrypto.encrypt(val, pubKey);
//passing public key as 2nd parameter is MANDATORY for RSA encryption

RSA Decrypt

let decrypted = encrypto.decrypt(base64encrypted);
console.log(decrypted);
//prints original message i.e. "alo"

Other methods for RSA

| Sr. number | Methods | Info | |------------|:-------------------------------------------:|-------------------------------------------------------------------------------------------:| | 1 | getPublicKey() | is a method that returns generated ZotPublicKey | | 2 | getDeSterilizePublicKey() | is a method which converts ZotPublicKey string to ZotPublicKey | | 3 | getSterilizePublicKey() | returns a ZotPublicKey string which can be sent to the other person. | | 4 | encrypt(value, ZotPublicKey) | used to encrypt String with RSA | | 5 | decrypt(value) | used to decrypt string using the password or ZotPrivateKey (no need to pass ZotPrivateKey) |

DES

DES Init

Encrypto encrypto = new Encrypto(Encrypto.DES, "the moon is scary sometimes"); 
//MANDATORY to pass password as 2nd parameter for DES
//It's suggested to pass the hash of the password instead of plain text

DES Encrypt

• Unsupported for Encrypto v1.*

HTML

• To use Encrypto in HTML script tag click here for encrypto.min.js CDN link
• To use Encrypto in HTML script tag click here for encrypto.js CDN link
• To import file directly (without npm) just copy the encrypto.js file from here and use it the folloring way:

//foo.js (foo = name of the file you use in your html code)
import Encrypto from "./encrypto.js";

let encrypto = new Encrypto('RSA', 128);
let enc = encrypto.encrypt('alo from js', encrypto.getZotPublicKey());
console.log(enc);

let dec = encrypto.decrypt(enc);

console.log(dec);
