John the Ripper password cracking tool (latest git revision) on a rented VDS with one NVIDIA RTX 5090 GPU and 16 vCPUs from the larger AMD EPYC 9354 CPU.

This demonstration compares password cracking speeds between standard Rocky Linux 9.6 sha512crypt hashes and RLC-H’s enhanced password hashing via yescrypt, testing both CPU and GPU performance against weak passwords from common breach lists.

The recording shows how RLC-H’s stronger password hashing significantly increases the time and computational resources required for successful password attacks.
