LLCryptoLib Overview

.NET Encryption Library

Add encryption, authentication, integrity services to .NET


LLCryptoLib is a .NET library which allows programmers to easily add encryption, integrity and authentication services to their software.

It is compatible with Microsoft .NET and Mono environments. It offers both symmetrical and asymmetrical text and stream encryption classes and hashing functions. It also offers full file shredding functions.

It is engineered to be easy to use and standard compliant, fully compatible with ASP.NET web applications and C#, Visual Basic .NET, Managed C++ .NET Applications. LLCryptoLib can be linked to managed (.NET) and unmanaged (COM) projects.
