Decoders

decB64B :: (UnexpectedDecodeErr f, Applicative f) => Decoding f "enc-B64" "enc-B64" c ByteString Source #

Effectful decoding for corruption detection. This protocol is used, for example, in emails. It is a well known encoding and hackers will have no problem making undetectable changes, but error handling at this stage could verify that email was corrupted.
