OpenPGP Library for .NET

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

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 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

• Added new exception DidiSoft.Pgp.Exceptions.NonPGPDataException, that indicates that the input is not a valid OpenPGP message
• Added method KeyPairInformation.CheckPassword(password) – checks is a password for a private key correct
• Added property KeyPairInformation.IsExpired – returns is this key expired
• Added method KeyPairInformation.IsExpiredOnDate(date) – returns will this key be expired on a given date
• Added static method KeyStore.OpenInMemory() – creates an in memory KeyStore
• Added static method KeyStore.OpenFile(file, password) – equivalent to the constructor KeyStore(file, password)
• Added method KeyStore.IsInMemory – checks is this KeyStore located in memory
• Added method KeyStore.GetSecretKeysData() – returns the private keys contained in this KeyStore serialized as bytes
• Added method KeyStore.GetPublicKeysData() – returns the public keys contained in this KeyStore serialized as bytes
• Added method KeyStore.GetPublicKeysWithUserId(userId) – returns the public keys with the specified userId serialized as bytes
• Added method KeyStore.GetPublicKeyWithKeyId(keyId) – returns the public keys with the specified keyId serialized as bytes
• Added overloaded method KeyStore.ImportPrivateKey(file)
• Added overloaded method KeyStore.ImportPrivateKey(file)
• Added method KeyStore.ExportPublicKeyStream(userId) – exports a public key into a Stream
• Added method KeyStore.ExportPublicKeyStream(keyId) – exports a public key into a Stream
• Added method KeyStore.LoadFromStream(stream) – suitable for loading a previously serialized in memory Keystore
• Added method KeyStore.SaveToStream(stream) – suitable for storing an in memory Keystore
• Added method KeyStore.CheckPassword(file, password) – checks is a password for a KeyStore correct
• Added new exception DidiSoft.Pgp.Exceptions.NonPGPDataException, that indicates that the input is not a valid OpenPGP message

What's new in OpenPGP Library for .NET 1.7.1

• Fixed decryption of conventional encrypted (PBE) files, created with McAfee E-Business server 7.x and PGP 2.6.x
• Fixed exception caused by keys exported from GnuPG GPA.
• Added method PGPLib.SignFileV3 – signes files with OpenPGP version 3 signatures for compatibility with PGP 6.5 and below
• Added method PGPLib.SignStringV3 – signes strings with OpenPGP version 3 signatures for compatibility with PGP 6.5 and below
• Added method PGPLib.SignAndEncryptFileV3 – signes and encrypts files in one pass with OpenPGP version 3 signatures for compatibility with PGP 6.5 and below
• Added method PGPLib.SignAndEncryptStringV3 – signes and encrypts strings in one pass with OpenPGP version 3 signatures for compatibility with PGP 6.5 and below

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)
