Crypto.Cipher.RC4
Description
Simple implementation of the RC4 stream cipher. http://en.wikipedia.org/wiki/RC4
Initial FFI implementation by Peter White peter@janrain.com
Reorganized and simplified to have an opaque context.

Arguments
| :: ByteString | The key |
| -> Ctx | The RC4 context with the key mixed in |
RC4 context initialization.
seed the context with an initial key. the key size need to be adequate otherwise security takes a hit.
generate :: Ctx -> Int -> (Ctx, ByteString) Source #
generate the next len bytes of the rc4 stream without combining it to anything.
RC4 xor combination of the rc4 stream with an input
