Detailed Description

This class is a helper for encrypted stream input.

It is used as a streambuf for an istream. It will buffer internally until a a complete message is available, where a complete message is comprised of nonce (initialization vector), length, data and MAC.

This class is typically not used directly, but is instantiated by XChaCha20Poly1305::Istream.
