+/*
+ * Example code for a decoder and encoder of "hash strings", with Argon2
+ * parameters.
+ *
+ * This code comprises three sections:
+ *
+ *   -- The first section contains generic Base64 encoding and decoding
+ *   functions. It is conceptually applicable to any hash function
+ *   implementation that uses Base64 to encode and decode parameters,
+ *   salts and outputs. It could be made into a library, provided that
+ *   the relevant functions are made public (non-static) and be given
+ *   reasonable names to avoid collisions with other functions.
+ *
+ *   -- The second section is specific to Argon2. It encodes and decodes
+ *   the parameters, salts and outputs. It does not compute the hash
+ *   itself.
+ *
+ * The code was originally written by Thomas Pornin <pornin@bolet.org>,
+ * to whom comments and remarks may be sent. It is released under what
+ * should amount to Public Domain or its closest equivalent; the
+ * following mantra is supposed to incarnate that fact with all the
+ * proper legal rituals:
