Allows you to control the user access to your application GUI components (menus, buttons, edits, tree views, radio groups, etc. every control) as well as to non visual functionalities. Just drag/drop and connect and you get a securized multiuser application.

With Security Builder you can:
- Build the security model of your Delphi application at design time with just few mouse clicks, - Add and remove users on fly,
- Change users profile on fly, Add and remove securized items on fly, Securize your non GUI functionalities,
- Set predefined User Groups - Supervisors, Power Users, ...

The library's two components:
- abSecurity - control center encapsulating the application security template, implementing all Security Builder functionalities,
- abActionList - ActionList control providing a connection to abSecurity component and to it's control center functionalities,
- and a TAction derivative called TabAction, adding the ability to Enable/Disable and change Visible/Invisible status.

Updated: New modes of operation like MAC only from plaintext/ciphertext and encryption/decryption into another buffer, leaving the original untouched. A unit dependency error was solved in the example application.

DCPcrypt is an open source library of cryptographic components (encryption and hash algorithms) for Borland Delphi 4, 5, 6, C++ Builder (3?), 4, 5, 6 and Kylix 1, 2 for Linux.

The idea behind DCPcrypt is that it should be possible to "drop in" any algorithm implementation to replace another with minimum or no code changes. To aid in this goal all cryptographic components are descended from one of several base classes, TDCP_cipher for encryption algorithms and TDCP_hash for message digest algorithms.

DCPcrypt v2 contains full implementations of the following algorithms:

  • Blowfish, Twofish
  • Cast-128, Cast-256
  • DES, 3DES
  • Ice, Thin Ice, Ice2
  • IDEA
  • Mars
  • Misty1
  • RC2, RC4, RC5, RC6
  • Rijndael (the new AES)
  • Serpent
  • TEA
  • Haval
  • MD4, MD5
  • RipeMD-128, RipeMD-160
  • SHA-1, SHA-256, SHA-384, SHA-512
  • Tiger

aecDES - advanced encryption component- DES Delphi implementation of the 'old faithful' of the block encryption algorithms. DES has a relatively short key length of 56 bits, but has stood the test of time to show that the quickest attack on DES is to search the entire keyspace for the correct key. DES is the most thoroughly inspected block ciphers.

Features:
ECB, CBC, CFB and OFB modes of operation
Automatically handles all padding of the input
High-level functions for encrypting strings, files, buffers and streams
Additional mode for producing CBC-MACs (keyed hashes)
Also includes support for base64 encoding and decoding strings
Full native Delphi source code included in Corporate version

Cost (without source code): Free!
Cost (with source code): $99

[ DIMime.exe ] [ 52,964 bytes ] [ Freeware ] [ With Source ]
[ D2 | D3 | D4 | D5 | D6 | K1 ]
DIMime is a lightening fast MIME (Base64) Encoder and Decoder for Borland Delphi. The core encoding and decoding routines are written in highly optimized Delphi Pascal which even beats most assembler code. Speed has been slightly improved as of version 1.60.

Both MimeEncode and MimeDecode have a straightforward, flexible and highly effective interface which makes them easy to use with buffers, strings and all other types you can imagine. Decoding does not mock about spaces, line breaks or incomplete data.

Mime encoding is possible with or wihout inserting line breaks. Additional helper functions easily code strings, streams, and files of practically unlimited size with only one single line of code.

An older version of DIMime is part of the Jedi Code Library (JCL).

  • Decompression is extremely fast and requires no memory.
  • The assembler optimized decompressor fits into less than 200 bytes of code.
  • Supports in-place compression and decompression.
  • Real-time decompression should be possible for any application.
Usage & Interfaces:
  • UCL API operates on blocks of memory.
  • Stream wrappers for sequential on-the-fly compression and decompression with complete Seek support.
  • Optimized helpers for Stream, AnsiString & WideString operations.
Freeware with sources, demos and help.

aecEllipticCurve - advanced encryption component- Public Key Encryption based on Elliptic Curves Delphi implementation of Elliptic Curve public key encryption. Elliptic Curves offer the best public key security with the smallest possible key length. The elliptic curve problem is considered to be significantly harder to solve than RSA, and can therefore offer a comparable level of strength in much shorter bit lengths.

Features:
160 bit keylength - roughly equivalent to 1024 bit RSA
Very fast
Performs Encryption, Decryption, Signing and verification
Performs key generation for symmetric encryption

    Available capabilities:

    • Encoding and decoding (encryption/decryption/signing/verifying)
    • Creating and verifying file detached (Open)PGP signatures

    • 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.
