`LlavesSHA2.zip` contains:

* `*_PASARELA_*.txt`: SHA-2 key required to sign and validate VPOS-2.
* `*_WALLET_*.txt`: use it only if Wallet was enabled for the merchant.
* Public and private RSA files: not required for Redirect.

<Warning>
  Each key registration immediately replaces the previous keys. Store the ZIP securely and regenerate only when necessary or according to the merchant policy.
</Warning>
