com.freiheit.gnupg | Main package. |
GnuPG for Java is a (currently GNU/Linux only) GnuPG-library based on the GPGME library. GPGME is the standard way to implement language bindings on top of GnuPG. You can use this library to encrypt, decrypt and sign data and verify signatures on data using an underlying gnupg/gpgme system.
The key management features are currently not finished. But the library can find/list keys with their signatures. Future versions will be able to do everything that gpgme can do.
This library uses JNI (Java Native Interface) to call GPGME-Library functions. Therefore, this library runs only on platforms for which GPGME is available. Furthermore, this library is tested only under 32-Bit Intel-based GNU/Linux.
This is an alpha release. Please expect problems. Although this is working code, this library is not finished and has known and unknown bugs.
Java for GnuPG is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public Licenseas published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version.
Please see COPYING in the source distribution for the complete licence.
So, if you need this library for another platform, if you find a bug or if you need a feature, please contact Stefan Richter.
Quickstart to encryption:
GnuPGContext ctx = new GnuPGContext();
GnuPGKey[] recipient = new GnuPGKey[1];
recipient[0] = ctx.getKeyByFingerprint("gpg-fingerprint of recipient (must be from your keyring)");
//attention: fingerprint should not contain spaces...
GnuPGData plain = ctx.createDataObject("I am a secret message.");
GnuPGData cipher = ctx.createDataObject();//this will contain the cipher after encryption
ctx.encrypt(recipient, plain, cipher);
System.out.println("Plain text: " + plain);
System.out.println("Cipher text: " + cipher);
