The RSA key pair generation will result in two files: pay_rsa_private_key.pem (private key) and pay_rsa_public_key.pem (public key) in the current directory. The former is to be kept secure by the merchant for signing critical interfaces, while the latter's uncommented content should be uploaded via the interface. EchoooPay's backend portal will then verify the interface using the provided public key.
