Here is a simplified conceptual example of how a developer extracts data from a local certificate using PHP or Python, without ever sending data to an external website:
The SII system strictly requires files to be signed using an authorized electronic certificate (such as a FNMT certificate in Spain). A digital signature ensures data integrity and non-repudiation. While the data remains visible in XML format, the signature block itself looks like a string of random characters.
Several online tools are available that can help decrypt SII-encrypted data. These tools are designed to simplify the decryption process and make it accessible to users without extensive cryptographic knowledge.
