Phan.\n\nIt uses core algorithm from ChaCha_ cipher designed by Daniel J. Bernstein.\n\nThe stdlib implementation is based on pyblake2_ module. It was written by Dmitry Chestnykh based on C implementation written by Samuel Neves. The documentation was copied from pyblake2_ and written by Dmitry Chestnykh.\n\nThe C code was partly rewritten for Python by Christian Heimes.\n\nThe following public domain dedication applies for both C hash function implementation, extension code, and this documentation\n\nTo the extent possible under law, the author(s) have dedicated all copyright and related and neighboring rights to this software to the public domain worldwide.
