blockcrypt v0.0.1-beta.21

Blockcrypt (beta)

Encrypt one or more secrets with plausible deniability by design.

Blockcrypt is used to encrypt one or more secrets (up to 4 by default) using encrypted headers which are indistinguishable from each other and padding resulting in plausible deniability by design.

Installation

$ npm install blockcrypt

Usage (simplified for demonstration purposes)

import { encrypt, decrypt, Secret } from "blockcrypt"

const secrets: Secret[] = [
  {
    message:
      "trust vast puppy supreme public course output august glimpse reunion kite rebel virus tail pass enhance divorce whip edit skill dismiss alpha divert ketchup",
    passphrase: "lip gift name net sixth",
  },
  {
    message: "this is a test\nyo",
    passphrase: "grunt daisy chow barge pants",
  },
  {
    message: Buffer.from("yo"),
    passphrase: "decor gooey wish kept pug",
  },
]

const block = await encrypt(secrets, kdf)

console.log(block)
// {
//   salt: <Buffer 0a 89 b8 fd a1 6d 06 36 86 76 f6 e3 82 2e 54 37>,

)
