LLCryptoLib

LLCryptoLib is a .NET library that offers encryption, integrity, and authentication services to programmers who want to enhance their software easily. It is compatible with both MS .NET and Novell Mono environments, and it also provides shredding methods.

This library offers both asymmetrical and symmetrical encryption classes and hashing functions for text and binary files. Additionally, it provides methods for public key and digital certificate management. It comes free of charge for non-commercial and academic purposes, while enterprise or commercial licenses may be bought (read the enclosed licensing options).

LLCryptoLib is engineered to be easy to use and compatible with ASP.NET Web Applications and Visual C#, Visual Basic .NET, and Managed C++ .NET Applications. This library can be utilized in both managed (.NET) and unmanaged (COM) projects.

Hashing algorithms available include CRC32, FCS16/32, GOST, ADLER32, HAVAL, MD2/4, MD5, SHA1-384, SKEIN, TIGER, RIPEMD160, and WHIRLPOOL. Encryption algorithms include ROT13, Playfair, PseudoDES, DES, Triple DES, Rijndael (AES), CAST5, ARC4, Blowfish, Threefish, and RSA.

Furthermore, digital certificates can be in PEM, CER, PFX, or X format, and text can be converted into binary via plain text (UTF8), hexadecimal (with four styles), and base storage shredding algorithms using US Department of Defense (DoD), Guttman Simple, Navso P-5329-26, German VSITR5, and HMG Infosec Standard 5.

Library features include .NET API Compliant algorithms that implement System.Security.Cryptography.SymmetricAlgorithm, asynchronous feedback on operations through delegates, and Enum's based algorithm choice. Additionally, MSDN-style documentation is available in both HTML and WinHelp formats.

LLCryptoLib is a part of the popular Folder Crypt software by LittleLite.
