This PR was the core part of adding support for 64-bit counter into
x.crypto.chacha20
module.Its contains some bits of
chacha20.Cipher
methods to aware this new changes, its include mainchacha20_block_generic
keystream generator.Most of the functionality to support for 64-bit counter was mostly completes. But, this PR does not fully activated support for 64-bit counter, its still fails when you try creates cipher with 64-bit counter.
My plan was after adding test files.
Thanks
