OpenPGP Library for Java

Implement OpenPGP cryptography in your Java application in less than an hour!

OpenPGP Library for Java provides two ways of development, with key store and with keys located in files. Includes methods for OpenPGP encryption, decryption, clear signing, signing and encryption, decrypt and verify, key pair generation, supports both files and streams.

The Library Supports:

JDK 1.4, 1.5, 1.6.
OS Linux (RedHat, SuSE), AIX, HP-UX, FreeBSD, Windows, Mac OS X.
JVM Sun, IBM, Diablo (FreeBSD)

The encrypted files created with the library are compatible with the OpenPGP standard, and can be opened with PGP (r)software and GnuPG.

Royalty free distribution

There are no hidden costs. Distribute the library with no fees to pay.

Value for money

Buy a single user license for the cost of just two developer days.

Trial VersionLimitations

[!] : Modification

Version 2.5.3

[!] KeyPairInformation.getKeyIDHex() has been changed to display the same Hex string as GnuPG and PGP (r).

[+] Added KeyStore.getUserIds() - list of all User Id's of the keys in this KeyStore instance

[+] Added KeyStore.getKeyHexIds() - list of all Key Id's in Hex form of the keys in this KeyStore instance

[+] Added KeyStore.getKeyIdForUserId(userId) returns the first Key ID for a given User Id

[+] Added KeyStore. getKeyIdForKeyIdHex(keyIdHex) returns the first Key ID for a given Key Hex Id

[!] KeyStore.listKeys() is modified to print similar output as PGP (r) 6.5

[+] Added KeyStore.setAutoSave(boolean) should the KeyStore file be auto saved after each operation.

[+] Added KeyStore.isAutoSave() that returns the auto saved status.

[+] Added KeyStore.isBackupOnSave() that returns is backup file creation on.

[+] Added KeyStore.setBackupOnSave(boolean) that sets should the old status of KeyStore be saved in
a file with the same name and extension .bak

OpenPGP Library for Java version 2.5

October 20th, 2010

[*] : Bug
[+] : New
[-] : Removed
[!] : Modification

List of changes:

[+] Added interface CompressionAlgorithm with constants for available compression algorithms.
[+] Added interface HashAlgorithm with constants for available hashing algorithms.
[+] Added interface CypherAlgorithm with constants for available cypher compression algorithms.

[+] Added methods PGPLib.getCompression() and setCompression(int),
that controls the used compression algorithm to be used during encryption. 

[+] Added methods PGPLib.getHash() and setHash(String),
that controls the used hashing algorithm to be used during encryption. 

[+] Added methods PGPLib.getCypher() and setCypher(String),
that controls the prefered symmetric cypher algorithm to be used during encryption.

[+] Added method KeyStore.importKeyRing,
that imports both public and private key (if present) from one file.

[+] Added method KeyStore.exportKeyRing,
that exports both public and private key (if present) in one file.

[+] Added method PGPLib.encryptFilePBE that makes the encrypted archive available for decryption
with both private key and a (if lost or not available) with a pass phrase.

[*] Fixed error while deleting key pair from KeyStore, when only public key exists.

[*] Fixed decryption of multi-recipient pgp files.

What our customers say:
I had a small amount of self-education on pgp encryption, of which I was completely unfamiliar. After I understood this, using the library made it very easy. It only took a few lines of code, and it worked after only a few tries. The application I am building is a critical part of a big implementation. Thanks for the great software. Also, when I was evaluating, I got the prompt answers I needed.
