Reorganized and simplified to have an opaque context.

newtype Ctx

The encryption context for RC4

Constructors

Ctx ByteString

Instances

Show Ctx

initCtx

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)

generate the next len bytes of the rc4 stream without combining it to anything.

combine

Arguments

:: Ctx

rc4 context

-> ByteString

input

-> (Ctx, ByteString)

new rc4 context, and the output

RC4 xor combination of the rc4 stream with an input

encrypt :: Ctx -> ByteString -> (Ctx, ByteString)

Deprecated: use combine instead

decrypt :: Ctx -> ByteString -> (Ctx, ByteString)
