io_utils library

Miscellaneous I/O utilities. This includes for using Pointycastle to encrypt or decrypt a stream of data, somewhat like javax.crytpo.CipherInputStream and javax.crypto.CypherOutputStream.

Classes

DecryptingStream

A wrapper around a DataInputStream that decrypts using a Pointycastle BlockCipher, resulting in a Stream<List<int>>. This is functionally similar to javax.crypto.CipherInputStream.

EncryptingSink

A wrapper around a Sink<List<int>> that encrypts data using a Pointycastle BlockCipher. This sink needs to buffer to build up blocks that can be encrypted, so it's essential that close() be called. This is functionally similar to javax.crypto.CipherOutputStream
