The token generation step!

Using the SHA-256 hash value, a unique token is generated, which is a non-sensitive equivalent of the PAN. This token is designed to protect the sensitive payment card data while still allowing for transactions to be processed.

Here's what happens during token generation:

1. The SHA-256 hash value is used as input.

2. A tokenization algorithm, such as a pseudorandom number generator, is applied to the hash value.

3. A unique token is generated, which is a non-sensitive representation of the PAN.

The token has the following properties:

- _Uniqueness_: The token is unique to the original PAN.

- _Non-sensitivity_: The token does not contain any sensitive information about the payment card.

- _Reversibility_: The token can be mapped back to the original PAN, but only by the tokenization system.

This token is now ready to be used for transactions, allowing for secure and compliant processing of payment card data!
