This Delphi package consists of two components and several classes. (1) Component TFHHSpellMaker. Enables compilation of spell check dictionaries. Includes methods for "reverse spell check" text file compression, approximately twice as effective as zip (given that you use an adequate dictionary with the same language as the text file). This method should be used as a complement to secret key encryption, instead of regular compression. Make sure your recipients share your dictionary. (2) Component TFHHSpellChecker. Since you have compiled comprehensive dictionaries and used them for text file compression, you might as well use them for spell checking too. This component hooks on to any TCustomMemo descendant and checks spelling with only one procedure call. (3) Class TWeakCipher. A 64 bit CFB mode stream cipher. The algorithm itself runs at approximately 7 MB per second on a Pentium II 300MHz computer. Don't believe us when we call it "weak": It uses two 32 bit discrete powers to encrypt and decrypt (which means that you may transmit 2 GB of data before any kind of linear cryptography might reveal a pattern). It is just that we are also dealing with REALLY strong cryptography. Coming up soon...
This package may be distributed freely, as long as no copyright notice is removed. However, no version control is guaranteed. We recommend that you purchase the registred version before distributing your source code.

HKSetup is a template project to create self-extracting zip files. The program Unzip's the zip with internal routines in the windows temporary directory, asks for confirmation, and executes (all of these are options) a exe file. This is perfect for making Install Shield's setups into one Self-setup Exe file. These routines are NOT encapsulated in a component, nor is the forms unit loaded, so only 80kb are added to the zip file. Very Easy to use.

HKStreams is a component that enables you to easily save and load many streams into one file. The streams can be stored with LHA compression if wanted, and can also be encrypted with blowfish. THKStreams is also smart, if you load afterwards an encrypted or compressed (or both) file, it will know how to read it, and can also call your event that asks the user for a password if needed. Can also handle corrupt and wrong passwords. Source and EXE demo included.

This component links to Lzh component and allows you to pack multiple files to a single Paradox table, like ZIP archive is doing. It encapsulate basic procedures as add a new file to archive, remove an existent file from archive, open an existent file from archive, etc. It requires the Lzh component which actually is included in ZIP. If you want to get the latest free version of Lzh component try the Link section on Delphi Home Page (we recommend you Delphi Super Page component archive).

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.
