Crate cryptocol

cryptocol crate provides libraries for cryptography.

This crate is optimized for Little-endian CPUs because Little-Endian CPUs are far more popular than Big-endian CPUs. For the information about Endianness (including Little-endian and Big-endian) .

Big-endian issue

This crate is just experimental for Big-endian CPUs. So, you are not encouraged to use this crate for Big-endian CPUs for serious purpose. Only use this crate for Big-endian CPUs with your own full responsibility.

Road Map for Version 1.0

This crate Cryptocol is planned to provide the following functionalities. The checked items have already been implemented including documentation at least 95%. The unchecked items have been implemented including documentation less than 95% or have not yet even been started to implement.

When the implementation of all the above functionalitis are completed, the version number 1.0.0.0 will be given. After that whenever another functionality is added to this crate, the version number will get higher beyond 1.0.0.0. Before the version number 1.0.0.0, the maximum version number will be 0.25.x.x since there are all twenty-five functionalities listed above. So, for example, even if the version number is 0.5.0.0, it does not mean that 50% of all functionalities are implemented.
