hex-transposition-cipher

hexadecimal transposition cipher for shuffle and reverse shuffling hex encoded cipher text for nodejs and the browser.

Adds an extra layer of protection to your already encrypted code's hex output by essentially turning it into nothing but valid hex.

info

// defaults
{
  decode: false, // set true for decrypt
  reverse: false, // reverse encrypted/decrypted hex string
}


// htc.keyGenSync()
const key = htc.keyGen(); //generates random hex key from the default key
console.log(key) // returns hex key ~ dont lose this
