Encryption Library Programs

Security toolkit with strong encryption and authentication. Supports many algorithms for symmetric/asymmetric encryption, authentication, and hashing. Free for non-commercial/shareware projects. Written in C. ActiveX and C++ wrappers are available.

Open SSL 0.9.7c lets applications use Secure Sockets Layer (v2/v3), Transport Layer Security (v1), and a general-purpose cryptography library, for data integrity, authenticity, and privacy security features. Perl or Cygwin needed for Win32 compile.

The Xceed Encryption library allows you to easily add strong encryption and decryption capability to your Windows applications. Supports the latest industry-standard strong encryption algorithms and offers both symmetrical and public-key cryptography

Affordable, powerful, and easy to use .NET Encryption/Hashing/Compression Library. Encrypt sensitive information such as passwords, credit cards and social security numbers.

The Encryption Toolkit includes all the tools you need to add file encryption and data encryption to your applications. The toolkit includes COM encryption objects with a standard interface for both the Pocket PC and Windows® desktop platforms.

.Net library to encrypt files with a very fast implementation of AES 256 bits and standard RC4 , the AES is adopted by NIST as an encryption standard , the RC4 is the standard RC4 encryption developed by RSA

Library with encryption functions and huge integer math functions. RSA public key, AES secret key encryption, SHA-512 hash function, PRNG: Blum-Blum-Shub and RSA, Diffie-Hellman, file shredding, compression and more. For every programming language.

HsCipherSDK is an Encryption Library providing an API to a suite of symmetric cryptographic algorithms and digital signing functions. The library includes block and stream cipher modules: AES, 3DES, ARC4, CAST-128, Blowfish,Twofish, MD5, SHA-1.

With Easy Compression Library you can add advanced compression and encryption functionality to your projects. Key Features: Advanced compression algorithms, Compression on-the-fly, No DLLs, compiles right into your EXE, Strong encryption

LLCryptoLib is a .NET library which allows programmers to easily add encryption, integrity and authentication services to their software. It is compatible with MS .NET and Novell Mono environments. It also provides shredding methods.
