/*
** Name:        pbkdf2.h
** Purpose:     API definition of PBKDF2 algoritm with Ascon
**              Password-based key derivation function based on ASCON.
**              (see https://tools.ietf.org/html/rfc8018)
** Based on:    Public domain Ascon reference implementation
**              and optimized variants for 32- and 64-bit
**              (see https://github.com/ascon/ascon-c)
**              and the paper "Additional Modes for ASCON Version 1.1"
**              by Rhys Weatherley, Southern Storm Software, Pty Ltd.
** Remarks:     API functions adapted for use in SQLite3 Multiple Ciphers
