PIN from PIN Block Extractor

Extract the original PIN from an encrypted PIN block using the PAN and encryption key. This tool supports ISO 9564 Format 0 and Format 1 PIN blocks.

Encrypted PIN Block (Hex)

PAN (Primary Account Number)

PIN Block Format

Encryption Key (Hex)

PIN extraction is the reverse process of PIN block creation. It involves:

Decrypting the encrypted PIN block using the encryption key
Identifying the PIN block format (Format 0 or Format 1)
Generating the PAN block from the PAN (using the rightmost 12 digits excluding the check digit)
XORing the decrypted PIN block with the PAN block (for Format 0)
Extracting the PIN length and PIN digits from the result
