Module yawPyCrypto._CipherStream

_CipherStream.py (Internal module)

Cipher stream classes. These are private to the module, and should never need to be used directly. In case you are interested in the inner workings of yawPyCrypto, feel free to browse the source. There are short commentaries on each function, which should get you started.
