Usage(JavaScript)

Implementation:-

``npm i @zozoto/encrypto`

or For HTML

RSA

$3

`js
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.
`

$3


`js
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
`

$3


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

$3

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

| 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

$3


`java
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
`

$3

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:

`js
//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);
