argon2cli

A command-line utility to test specific Argon2 instances on your system. Latest Windows, Linux and other release are here.

To show usage instructions, run:

./argon2cli -h

With arguments

./argon2cli --pass password --salt somesalt -m 32 -p 4 -i 2 -l 32 -t argon2i

Password   : password
Salt       : somesalt (in Base64 : c29tZXNhbHQ)
Memory: 32 KiB, Iterations: 2, Parallelism: 4, Hash length: 32, Algo: Argon2i)
===================================
Hex hash   : 85724a55cdca41f067be4d9f68dfcc5d0289a5f664fd96b0d6777a65672080ed

Execution Time : 0.017565563 s

No arguments or missing some of them

With no arguments or missing some of them, it use this defaults values for speed test:

• pass = password
• salt = somesalt
• memory = 65536 KiB
• parallelism = 4
• iterations = 2
• hash length = 24
• argon type = argon2i

./argon2cli

For use in script, the flags --oh (only output hash) or --op (only output phc string) are very usefull.

./argon2cli --op
$argon2i$v=19$m=65536,t=2,p=4$c29tZXNhbHQ$RdescudvJCsgt3ub+b+dWRWJTmaaJObG

./argon2cli --oh
