Argon2i Code




Argon2 is a key derivation function that was selected as the winner of the 2015 Password Hashing Competition. It was designed by Alex Biryukov, Daniel Dinu, and Dmitry Khovratovich from the University of Luxembourg. The reference implementation of Argon2 is released under a Creative Commons CC0 license (i.e. public domain) or the Apache License 2.0, and provides two related versions:

  • Argon2i is optimized to resist side-channel attacks. It accesses the memory array in a password independent order.
  • Argon2id is a hybrid version. It follows the Argon2i approach for the first half pass over memory and the Argon2d approach for subsequent passes. The RFC recommends using Argon2id if you do not know the difference between the types or you consider side-channel attacks to be a viable threat.
