Delphi is an object-oriented pascal compiler for the Windows platform. Kylix is a sister pascal compiler for Linux. Pascal is well-suited for straight-forward implementations of cryptography algorithms. 1. Advanced Encryption Components by TSM, Inc. - Professional quality tools for adding symmetric (Blowfish, Twofish, and Rijndael) and public key encryption (Elliptic Curve, RSA) into Delphi and C++Builder applications, plus cryptographic hashes and copy protection software. Freeware components (without source) or commercial versions with Delphi source code. 2. Ciphersaber Home Page - Support crypto freedom by learning how to write your own strong encryption program. This site explains concept and implementation ideas. 3. Delphi Cryptography Page - 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. 4. Delphi Cryptography Stuff - 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. 5. efg's Cryptography and Math Functions - 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. 6. MD5.pas - An implementation of the MD5 algorithm for Borland Delphi 4 and higher. Includes source code and demo project. 7. PC1 128-bit Stream Cipher - Implementation of the PC1 128-bit stream cipher algorithm in various languages. Freeware (even for commercial use) with Delphi source code. 8. StreamSec StrSecII - 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. 9. PGP Components for Delphi - Provide encoding and decoding, creating and verifying file detached signatures, key management functions (DH/DSS, RSA), keyserver functions, utilities. [Open source, MPL] 10. Triade Systems NEW! - 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. 11. XTea Encryption for Delphi NEW! - Delphi implementation of XTea encryption algorithm and also utility for embedding encrypted strings into Delphi application.
