real-chat

multiparty encrypted chat. a wrapper around private-box.

install

npm install real-chat

use

var real  = require('real-chat')
var alice = real.keypair()
var bob   = real.keypair()
var msg   = "hello"

// encrypt + decrypt
var ciphertext = real.encrypt(msg, [alice.publicKey, bob.publicKey])
var cleartext  = real.decrypt(ciphertext, alice.secretKey)
console.log(cleartext)
// "hello"

api

real.keypair()

generate ed25519 keypair

real.encrypt(string, [publicKeys...], [maxRecipients=7])

encrypt string to some array of ed25519 public keys, where the length of the array is no longer than maxRecipients.

NOTE: maxRecipients can't be more than 255. see private-box.

real.decrypt(ciphertext, secretKey)

decrypt ciphertext with a secret key.

real.stringify(ctxt) / real.parse(str)

convenience functions for sending ciphertext over the wire.

var ciphertext = real.encrypt(msg, [alice.publicKey, bob.publicKey])
// turn ciphertext into a string, so we can send it e.g. over post request
var serialized = real.stringify(ciphertext) 
// now turn it from a string back into a buffer, so we can decrypt it
var deserialized = real.parse(ciphertext)
var cleartext  = real.decrypt(deserialized, alice.secretKey)
