mde_crypt

Encrypt data with matrix dot product.

This is a prototype planned to be implemented as a parallelised cuno module

Install

npm i -g mde_crypt

CLI

Encrypt

ex: encrypt my_text.txt with 8 by 8 matrices and output to my_enc.mde, read key from key.txt and generate a key if none found

mde enc -i my_text.txt -o my_enc.mde -k key.txt -s 8

Decrypt

decrypt my_enc.mde to stdout

mde dec -i my_enc.mde -k key.txt

API

the package need to be installed as a non-global npm i mde_crypt

Encrypting

const MDE = require('mde_crypt');

// Encrypt 'Hello World' String with a new random key
const encrypted = MDE.Encrypt("Hello World", MDE.Keygen.random(3));

console.log(encrypted);

Decrypting

// Decrypt
const recovered = MDE.Decrypt(encrypted.data, encrypted.key);
console.log(recovered);

Usefull utils

// Get key as a matrix
const key_matrix =
  MDE.Keygen.ascii_to_key_matrix("abcd");

// Get random ascii key N by N
const key_matrix =
  MDE.Keygen.random(2);
