Blowfish encryption in TypeScript with custom schedule

Inspired by egoroof-blowfish and melia

Example

import blowfish from "@sighmir/blowfish";

const bf = blowfish("my_key");
const buffer = Buffer.from("blowfish");

bf.encipher(buffer);
console.log(buffer); // c8a2de2a895325f5

bf.decipher(buffer);
console.log(buffer); // 626c6f7766697368
