Freeware components (without source) or commercial versions with Delphi source code.
- PC1 128-bit Stream Cipher - http://membres.lycos.fr/pc1/
Implementation of the PC1 128-bit stream cipher algorithm in various languages. Freeware (even for commercial use) with Delphi source code.
- Ciphersaber Home Page - http://ciphersaber.gurus.com/
Support crypto freedom by learning how to write your own strong encryption program. This site explains concept and implementation ideas.
- Delphi Cryptography Page - http://www.cityinthesky.co.uk/cryptography.html
Implementations by Dave Barton of many of the most useful symmetric encryption algorithms (Blowfish, Twofish, IDEA, Rijndael, and Serpent) and message digests (RipeMD-160, SHA-1, and Tiger). Freeware with Delphi source code.
- Triade Systems - http://triade.studentenweb.org/GInt/index.htm
Implementations of FGINT (Fast Gigantic INTegers) and many asymmetric encryption algorithms (RSA, DSA, ElGamal, Elliptic Curve, EC-DSA, and EC-ElGamal). Freeware with Delphi and free pascal source code.
- Simple PGP Library - http://www.oz.net/~srheller/spgp/
Win32 DLL written in Delphi encapsulating important functions of the PGP for Windows API (versions 5.5 through 6.58). It exports a simplified interface with only "strings" and "integers". Freeware with Delphi source code.
- Digital Keys Library - http://www.ritlabs.com/dklib/index.html
Win32 DLL written in Delphi with a set of high-level functions to encrypt text and/or add a digital signature. Utilizes RSA, IDEA, and MD5. Data packet and key format compatible with PGP, Slumberger, and Dekart. Freeware (source code in Delphi available for a fee).
- efg's Cryptography and Math Functions - http://www.efg2.com/Lab/Library/Delphi/MathFunctions/Cryptography.htm
Comprehensive compilation of cryptography and high-precision math resources for Delphi (mirrored on Borland's website). Computer lab also features dozens of practical mathematics and graphics projects. Delphi source code with quality annotations.
- Delphi Cryptography Stuff - http://www.csd.net/~daves/delphi/
Implementations by Dave Shapiro of two symmetric encryption algorithms (Blowfish and DES) and several message digests (MD2, MD4, MD5, SHA-1, and RipeMD-160). Freeware with Delphi source code.
- MD5.pas - http://www.fichtner.net/delphi/md5.delphi.phtml
An implementation of the MD5 algorithm for Borland Delphi 4 and higher. Includes source code and demo project.
- StreamSec StrSecII - http://www.streamsec.com/
A collection of optimized cryptography components and routines for Delphi 4-6. The integrated ASN.1 support allows building of X.509 certificates using native Delphi code. Also implements 3DES, Twofish, and Rijndael (AES) in ECB, CBC, OFB, CFB, CTR, PCFB and ABC modes.
