|

* 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: |
