List Crypto

Caesar Cipher

Description

Name	Params	Type Data	Nullable	Description
caesar	type	string	✖️	d, decode, e, encode
	source	string	✖️	plaintext
	key	integer	✔️	key shifter, default value is 13

Sample

const c = new Crypto;

console.log(c.caesar("e", "Defri Indra Mahardika", 3));
console.log(c.caesar("d", "Ghiul Lqgud Pdkduglnd", 3));

// Output : 
// Ghiul Lqgud Pdkduglnd
// Defri Indra Mahardika

Morse

Description

Name	Params	Type Data	Nullable	Description
morse	type	string	✖️	d, decode, e, encode
	source	string	✖️	plaintext
	options	object	✔️	you can custom short, long, and space symbol.

Sample

const c = new Crypto;

console.log(c.morse("e", "defri indra mahardika", {
    short: "+"
}));

// Output : 
// -++ + ++-+ +-+ ++ / ++ -+ -++ +-+ +- / -- +- ++++ +- +-+ -++ ++ -+- +-

ROT13

Description

Name	Params	Type Data	Nullable	Description
rot13	source	string	✖️	plaintext

Sample

const c = new Crypto;

console.log(c.rot13("defri indra mahardika"));

// Output : 
// qrsev vaqen znuneqvxn

NATO

Description

Name	Params	Type Data	Nullable	Description
nato	type	string	✖️	d, decode, e, encode
	source	string	✖️	plaintext

Sample

const c = new Crypto;

console.log(c.nato("e", "defri indra mahardika"));

// Output : 
// Delta Echo Foxtrot Romeo India(space) India November Delta Romeo Alfa(space) Mike Alfa Hotel Alfa Romeo Delta India Kilo Alfa

Affine Cipher

Description

Name	Params	Type Data	Nullable	Description
affine	type	string	✖️	d, decode, e, encode
	source_text	string	✖️	plaintext
	keys	Array	✖️	must contain 2 key number . eg : [3, 1]
	custom_letters	string	✔️	eg : KLMNOPQRSTUVWXYZABCDEFGHIJ

Sample

const c = new Crypto;
let custom_letters = "OPQRSTUVWXYZABCDEFGHIJKLMN";
let ciphertext = "Iloyx Xmiyz Jzuzyixdz";
let plaintext = "Defri Indra Mahardika"
let key = [3, 1];

console.log(c.affine("e", plaintext, key, custom_letters));
console.log(c.affine("d", ciphertext, key, custom_letters));

// Output : 
// Delta Echo Foxtrot Romeo India(space) India November Delta Romeo Alfa(space) Mike Alfa Hotel Alfa Romeo Delta India Kilo Alfa

Vigenere Cipher

Description

Name	Params	Type Data	Nullable	Description
vigenere	type	string	✖️	d, decode, e, encode
	source	string	✖️	plain text
	keys	string	✖️	eg : programme
	custom_letters	string	✔️	eg : KLMNOPQRSTUVWXYZABCDEFGHIJ

Sample

const CryptoNode = require('cryptonode.js')

const c = new CryptoNode;
let plain_text = "Defri Indra Mahardika";
let cipher_text = "Svtxz Izhgr Agyadhxbo";
let key = "programe";

console.log(c.vigenere('e', plain_text, key));
console.log(c.vigenere('d', cipher_text, key));

// Output : 
// Svtxz Izhgr Agyadhxbo
// Defri Indra Mahardika

Base 64

Description

Name	Params	Type Data	Nullable	Description
b64	type	string	✖️	d, decode, e, encode
	source	string	✖️	plain text

Sample

const CryptoNode = require('cryptonode.js');
const c = new CryptoNode;

c.b64("encode", "any carnal pleasu");
c.b64('e', "##Defri indra Mahardika*&^%`");

c.b64("d", "YW55IGNhcm5hbCBwbGVhc3U=");
c.b64('decode', "IyNEZWZyaSBpbmRyYSBNYWhhcmRpa2EqJl4lYA==");

// Output : 
// YW55IGNhcm5hbCBwbGVhc3U=
// IyNEZWZyaSBpbmRyYSBNYWhhcmRpa2EqJl4lYA==
// any carnal pleasu
// ##Defri indra Mahardika*&^%`
