OpenPGP.js browserify javascript methods

README.md

1. Install browserify

npm install -g browserify

2. Save the pgp.util.js contents to a file.

3. Run browserify ./pgp.util.js -o ./openpgp.bundle.js

4. Now include openpgp.bundle.js in any HTML page, and the encrypt, decrypt, and generate methods will be available on the window object.

pgp.util.js

var openpgp = require('openpgp');

window.generate = (name, email, passphrase, numBits) => {

  const userId = name = " <" + email + ">";

  const options = {
      numBits: numBits || 2048,
      userIds: [userId],
      passphrase,
  };

  return openpgp.generateKey(options);
}

window.encrypt = (privatekey, publickey, passphrase, message) => {
  const privatekeyobj = openpgp.key.readArmored(privatekey).keys[0];
  return privatekeyobj.decrypt(passphrase).then(decrypted => {
    const options = {
      data: message,
      publicKeys: openpgp.key.readArmored(publickey).keys,
      privateKeys: [privatekeyobj],
    };
    return openpgp.encrypt(options);
  }).catch(error => {
    return Promise.reject({error});
  });
}

window.decrypt = (privatekey, publickey, passphrase, pgpmessage) => {
  const privatekeyobj = openpgp.key.readArmored(privatekey).keys[0];
  return privatekeyobj.decrypt(passphrase).then(decrypted => {
    const options = {
      message: openpgp.message.readArmored(pgpmessage),
      privateKeys: [privatekeyobj],
    };
    if (publickey) {
      options.publicKeys = openpgp.key.readArmored(publickey).keys;
    }
    return openpgp.decrypt(options);
  });
}
