Build encryption into your applications. OpenPGP Library for .NET includes methods for OpenPGP encryption, decryption, clear signing, one pass sign and encrypt, decrypt and verify, key generation, supports both key store and keys located in files. Entirely written in managed code, there are no external third party dependencies. OpenPGP Library decrypts and encrypts files that can be opened with the following software; PGP ®, PGP ® Universal Server, McAfee E-Business Server, GnuPG (gpg), WinPT and Articsoft FileAssurity.

OpenPGP Library for .NET

NET OpenPGP library, 100% managed code.

User-friendly API in few lines of code.

OpenPGP and GnuPG compatible.

Royalty free distribution.

Some of the features provided by OpenPGP are:

Encrypt and decrypt files

Digitally sign and verify signatures

Asymmetric encryption with pairs of public and private keys, creates random session keys, uses them to encrypt files with a symmetric algorithm, and adds the session key encrypted with the recipient public key

The encrypted files can be either in binary format or ASCII text (called ASCII armored) format

Keeps private keys encrypted

Signs third party public keys

The encrypted file can be compressed (ZIP, ZLib, BZip2)

The most widely used file name extensions for public key files are: .pkr, .asc, .pubkr, .pgpkey

The most widely used file name extensions for private key files are: .skr, .asc, .seckr, .pgpkey

The most widely used file name extensions for encrypted files are: .pgp (binary format), .asc (ASCII armored format)

What's new in OpenPGP Library for .NET 1.7.3

Inspecting the contents of OpenPGP encrypted data

Added namespace Didisoft.Pgp.Inspect

Added class Didisoft.Pgp.PGPInspectLib that provides methods for inspecting the content of OpenPGP data

Added class Didisoft.Pgp.ContentItem that represents information for an item in an OpenPGP archive

Web of Trust

Added enum TrustLevel that holds supported trust values

Added methods for marking a public key as Trusted introducer

Added methods for signing a public key

Added methods for explicitly setting the Trust of a key located in a KeyStore

Added methods and property for checking the trust value of a given key

Detached signatures

PGPLib.DetachedSignFile creates a detached OpenPGP signature for a file

PGPLib.DetachedSignStream creates a detached OpenPGP signature for a data stream

PGPLib.DetachedSignString creates a detached OpenPGP signature for string message

PGPLib.DetachedVerifyStream verifies a detached OpenPGP signature against a data stream

PGPLib.DetachedVerifyString verifies a detached OpenPGP signature against a string message

Partial match User Id's

Added property KeyStore.PartialMatchuserIds - if enabled the methods that search keys in a KeyStore by User Id will match them on part of the User Id as well

Expired and revoked keys

Added property PGPLib.UseExpiredKeys - check are the encryption keys expired

Added property PGPLib.UseRevokedKeys - check are the encryption keys revoked

New Exceptions:

Added class Didisoft.Pgp.Exceptions.IntegrityCheckException (extends PGPException) thrown if an integrity protected OpenPGP archive is corrupted

Added Didisoft.Pgp.Exceptions.KeyIsExpiredException (extends PGPException) thrown from all Encrypt and SignAndEncrypt methods when the supplied public key is expired. Can be suppressed with PGPLib.UseExpiredKeys

Added Didisoft.Pgp.Exceptions.KeyIsRevokedException (extends PGPException) thrown from all Encrypt and SignAndEncrypt methods when the supplied public key is revoked. Can be suppressed with PGPLib.UseRevokedKeys

What's new in OpenPGP Library for .NET 1.7.2
