Three components are provided that enable applications to support Windows Explorer file drag and drop. The components are:

• TPJDropFiles - This windowed component catches files dropped anywhere over its window. It can act as a container for other components.
• TPJFormDropFiles - This non-visual component catches files dropped anywhere on its form, including the non-client areas.
• TPJCtrlDropFiles - This non-visual component catches files dropped on an associated TWinControl or TFrame.

Key features of these components are:

• An OnDropFiles event is triggered when files are dropped.
• The names of dropped files are made available through the Files array property. For convenience, the name of the first file is also stored in the FileName property.
• The list of dropped files can be configured to include only files, only folders or all files and folders.
• Dropped folders can be recursed so that all the files and sub-folders in each of the dropped folders are listed.
• Filters can be applied to the dropped files and folders. This is done in one of two ways: (1) by handling the OnFileFilter event and deciding which files and folders to pass through the filter and (2) by linking the drop file component to a special file filter component, derived from the abstract TPJFileFilter. In this case the dropped files are automatically filtered by the filter component. Two filter components are provided: TPJExtFileFilter that filters according to file extensions and TPJWildCardFileFilter that filters using DOS-style wildcards. Developers can create further filter components by deriving from TPJFileFilter.
• The mouse co-ordinates where the files were dropped can be retrieved, as can a reference to any control under the mouse cursor at the time.
• The OnBeforeDrop event can be used to do pre-processing before the files are actually dropped.
• The IsFolder array property tells if an equivalent item in the Files list is a file or a folder.
• The owning window can be brought to the front when files are dropped.
• Some design time assistance is provided by component and property editors.

A Delphi 3-7 OpenHelp compatible help file is supplied. Additionally an a-link keyword file is provided for use with Delphi 6/7.

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 4.5.2:

• Signing data without using PGP's passphrase dialog in TPGPEncode shouldn't cause access violations anymore.
• CreateX509CertificateFromRequest in X509Funcs.pas now returns a CertPropsList instead of a CertPropsRec.
• GetKeySetByAnyID in KeyFuncs.pas doesn't try to process non-empty blank IDs (spaces, e.g.) anymore.
• PGP's dialog for certificate selection shouldn't occasionally hide in background anymore.

Universal Encode/Decode algorithms for Base16, Base32 and Base64

• Standard Base16, Base32 and Base64 encoding/decoding functions
• Reference: RFC 3548, full compatibility
• Full MIME suppport
• Supported work with Memory, Stream, String and Files
• Supported work with padding keys (required numbers  of '=' at the end of the encoded array)
• You may easily create your own Encode/Decode functions  based on your own specific codes, from Base2 up to Base128
