Data.Conduit.Crypto

This module provides a function to decrypt a padded and encrypted stream of ByteStrings.

Decrypt

decryptPaddedStream

Arguments

:: Exception e

=> BlockCipher cipher

=> Monad m

=> e

The exception to throw in case of a padding error

-> Int

The chunk size (in Bytes, you may use defaultChunkSize, will be modified to be a guaranteed multiple (at least 1) of the blockSizeBytes)

-> (IV cipher -> ByteString -> (ByteString, IV cipher))

The decrypt function

-> IV cipher

The IV (see BlockCipher)

-> ConduitT ByteString ByteString m ()
