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.

It offers both asymmetrical and symmetrical encryption classes and hashing functions for text and binary files plus full shredding capabilities. It also offers methods for digital certificates and public key management. It is free for non commercial uses.

It is free for students and academic purposes. Enterprise or commercial licenses must be purchased (see enclosed licensing options).

It is engineered to be easy to use and standard compliant, fully compatible with ASP.NET Web Applications and Visual C#, Visual Basic .NET, Managed C++ .NET Applications.

LLCryptoLib can be linked to managed (.NET) and unmanaged (COM) projects.
