Build Status

W3C XML Encryption implementation for node.js (http://www.w3.org/TR/xmlenc-core/)

Usage

npm install xml-encryption

encrypt

var xmlenc = require('xmlenc');

var options = {
  rsa_pub: fs.readFileSync(__dirname + '/your_rsa.pub'),
  pem: fs.readFileSync(__dirname + '/your_public_cert.pem'),
  encryptionAlgorithm: 'http://www.w3.org/2001/04/xmlenc#aes256-cbc',
  keyEncryptionAlgorighm: 'http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p'
};

xmlenc.encrypt('content to encrypt', options, function(err, result) { 
    console.log(result);
}

Result:

decrypt

var options = {
    key: fs.readFileSync(__dirname + '/your_private_key.key'),
};

xmlenc.decrypt('<xenc:EncryptedData ..... </xenc:EncryptedData>', options, function(err, result) { 
    console.log(result);
}

// result

decrypted content

Supported algorithms

Currently the library supports:

However, you can fork and implement your own algorithm. The code supports adding more algorithms easily
