antiSocial

antisocial-encryption module

Implement Hybrid Cryptosystem used for user to user encryption of messages
using previously exchanged public keys

https://en.wikipedia.org/wiki/Hybrid_cryptosystem

``
npm install antisocial-encryption
`

$3

`
var cryptography = require('antisocial-encryption');

cryptography.getKeyPair(function (err, keypair) {
if(err) {
// ...something went wrong...
}

kp is an object with 2 properties
{
'public': 2048 bit rsa key,
'private': 2048 bit rsa key
}

// now you can do something with the keypair
// like save it in local data store and hand
// the public key to the peer you want to exchange
// encrypted messages with.
});
`

$3

`
var cryptography = require('antisocial-encryption');
var data = JSON.stringify({ 'foo': 'bar' });
message = cryptography.encrypt(publicKeyOfRecipient, privateKeyOfSender, data);
`

The resulting message is an object containing the encrypted data, a signature and an encrypted password which can only be decrypted by the recipient. This message can now be securely transmitted to the intended recipient.

$3

`
var cryptography = require('antisocial-encryption');
var decrypted = cryptography.decrypt(publicKeyOfSender, privateKeyOfRecipient, message);

decrypted.valid is false then the error description is in decrypted.invalidReason

if decrypted.valid is true, the decrypted information is in decrypted.data.
