Interactive Thales payShield 10K HSM simulator. Practice real host commands (A0, CA, M0…) with actual cryptographic algorithms — no physical hardware required. Free.
Run authentic HSM host commands against a faithful emulator of the Thales payShield 10K: key generation and import (A0/A6), KCV calculation, PIN block translation, MAC generation, and key block (TR-31) operations — all executing real cryptography in your browser.
