See Also: Chilkat Crypt.NET is an advanced encryption component that offers both RSA public-key encryption with digital signatures as well as symmetric encryption algorithms including AES (Rijndael), Blowfish, and Twofish. It provides the ability to easily create digital signatures for files or memory data, or verify digital signatures against incoming data or files. It allows for the use of any Cryptographic Service Provider, including Smart Card implementations from 3rd-party vendors. It also provides easy access to information about digital certificates and the ability to add and delete certificates from certificate stores found in the registry, filesystem, or even directly in memory.
