PIN for PVV Finder

Search all 10,000 PINs (0000–9999) to find which one yields a specific PVV

💳 Card & Account Data

13–19 digit card number. Spaces are allowed.

The PVV value you want to find the PIN for.

Key index (1–6) selecting the PVK pair.

🔑 PIN Verification Key (PVK)

32 hex characters (16 bytes). The double-length 3DES key used for PVV encryption.

How it works: This tool performs an exhaustive brute-force search across all 10,000 possible 4-digit PINs (0000–9999). For each candidate PIN, it computes the PVV using the Visa algorithm (3DES ECB encryption + decimalization) and checks if it matches your target PVV.

Collisions: Since PVV is only 4 digits (10,000 possible values) and we search 10,000 PINs, it's statistically expected that multiple PINs will produce the same PVV. On average, you'll see ~1–2 matching PINs per search.

Performance: The search runs entirely in your browser using chunked processing to keep the UI responsive. Typical completion time is under 2 seconds.

What is the PIN for PVV Finder?

The PIN for PVV Finder searches all 10,000 possible PINs (0000-9999) to find which PIN produces a specific PVV value, given the PAN and PVV Key Pair. This is used for PIN recovery in HSM testing environments.

🛠️ How to Use
  1. Enter the PVV Key Pair (32 hex characters).
  2. Enter the PAN and PVKI.
  3. Enter the target PVV (4 digits).
  4. Click Search to find the matching PIN.
❓ FAQ

How long does the PIN search take?

The search tests all 10,000 possible 4-digit PINs and typically completes in under a second since all computation runs client-side in your browser.
