The `LlavesSHA2.zip` file contains the merchant keys:

* `*_PASARELA_*.txt`: SHA-2 key used to sign and validate VPOS-2 operations.
* `*_WALLET_*.txt`: use it only if Wallet was enabled by the sales advisor.
* Public and private RSA files: not required for this integration.

<Warning>
  Registering new keys immediately replaces the current keys. Store the ZIP securely and regenerate only when necessary or according to the merchant security policy.
</Warning>
