The FCL provides classes for manipulating all elements of the .NET Framework's Code Access Security model, including security policies, security principals, permission sets, and evidence. These classes also support cryptographic algorithms such as DES, 3DES, RC2, RSA, DSig, MD5, SHA1, and Base64 encoding for stream transformations.
