These sources provide a Delphi (2-8 and 2005) direct interface to PGP requiring a preceding (!) full installation of PGP 6.5.x, 7.x, 8.x or 9.x.

Available capabilities:

• Encoding and decoding (encryption/decryption/signing/verifying)
• Creating and verifying file detached (Open)PGP signatures
• Importing, exporting, revoking, deleting keys & certificates
• Several key & certificate management functions
• Key & certificate generation (DH/DSS, RSA)
• x.509 certificate & S/MIME support
• Keyserver functions
• Some utilities

New in Version 4.5.1:

• Certificate selection now uses a certificate specific PGP dialog in some places.
• The key selection dialog for S/MIME encryption only shows certified keys in TPGPEncode.
• A SignCertUserName property has been added to TPGPEncode to ensure the proper signing certificate being used for S/MIME.
• Some internal changes have been applied to X509Funcs.pas and KeyFuncs.pas which required adding a new unit called ASN1.pas.
• The TUserIDs list type defined in KeyPropTypes.pas has been extended to provide X509Types and ChainValidities for certificates.
• Some new error codes have been added to pgpErrors.pas.
• More X509 related enhancements and fixes.

This unit provides various customisable message dialog box components. Three components are installed on the component palette. They are:

• TPJWinMsgDlg
  This component wraps the Windows MessageBoxIndirect API call and displays a message box based on that provided by Windows. This component will be suitable for most purposes and has the lighter footprint.
• TPJVCLMsgDlg
  This component uses the Delphi VCL CreateMessageDialog function to create a form based message box. (CreateMessageDialog is used by the standard Delphi MessageDlgXXX functions). The component provides more flexibility than either the Delphi functions or TPJWinMsgDlg. It should be used when it is necessary to display buttons or combinations of buttons that are not supported by the WindowsAPI message box or when a finer degree of control over the appearance and behaviour of the message box is required. TPJVCLMsgDlg supports all the features of TPJWinMsgDlg and extends them.
• TPJMessageDialog
  This is an updated version of the component supplied in release 1 of this unit. Various bugs have been fixed and the handling of user icons improved. This component is only provided for backwards compatibility with existing projects that use the old version. It exposes the same properties as the old component. Some of these properties vary from those common to TPJWinMsgDlg and TPJVCLMsgDlg. It is recommended that TPJWinMsgDlg or TPJVCLMsgDlg are used in new projects.

A demo project is included along with an OpenHelp compatible help file that integrates with Delphi 3-7.

System information classes and associated global variables. Information is provided via:

• TPJComputerInfo: a static class that provides information about the user's computer.
• TPJSystemFolders: a static class that gets full path of certain system folders.
• TPJOSInfo: a static class that provides information about the Windows operating system including platform, product and edition, service packs, version numbers, product ID etc.
• Global Win32XXX variables: extra variables to those provided by the SysUtils unit that provide extended OS version information on later NT platform OSs.

Extended operating system detection improved in this release: can now detect Windows Vista, XP Tablet and XP Media Center editions, and WOW64 subsystem of 64 bit Windows.

The TPJSysInfo component and a set of functions that were provided in earlier versions of the unit are also included but are now deprecated.

Some OS detection code based on a translation of example C code on MSDN.
