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.
