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.
Triade Systems
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.
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.
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.
Ciphersaber Home Page
Support crypto freedom by learning how to write your own strong encryption program. This site explains concept and implementation ideas.
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.
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.
MD5.pas
An implementation of the MD5 algorithm for Borland Delphi 4 and higher. Includes source code and demo project.
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.
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]
Simple PGP Library
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.
