pin parameter, encrypted using a public key generated.pin parameter is not provided in the request, the PIN will be automatically generatedpin parameters must be contain encrypted data encoded in Base64 format. Encryption is performed using the RSA algorithm with PKCS-1.5 padding and the partner’s RSA public key. To retrieve the original values, the data must first be Base64-decoded, then processed using the partner’s RSA private key with RSA-PKCS-1.5 padding.
