Development of this project has been migrated to: https://codeberg.org/GlitchedPolygons/Argon2GUI
Argon2 GUI is an easy, minimal and user friendly graphical user interface around the open-source crypto library "Argon2", which is written entirely in C and Apache-2.0 / CC0-1.0 dual-licensed, available on github.com/P-H-C/phc-winner-argon2.
It's very handy for usage during development and/or for testing and implementing web services of any kind where passwords are involved.
Argon2 is a great way of hashing passwords. NEVER store passwords in plaintext!
This GUI's source code is GPL-3.0 licensed and available on github.com/GlitchedPolygons/Argon2GUI - but also available for purchase on glitchedpolygons.com (ships with some cool, additional stuff, PDF files/manual, comfy .RPM and .DEB files for easy installation on Linux, etc...).
Please consider buying it from there to support the development of nifty tools like this :)
Argon2 GUI is available for Windows, Mac and Linux on the x64 architecture respectively. More are potentially supported, but not officially tested.
