A: Certyfirma provides advanced electronic signatures (AES) as defined under the eIDAS Regulation (EU Regulation No 910/2014) and equivalent frameworks like the ESIGN Act in the U.S. Advanced electronic signatures are designed to offer a higher level of security and legal validity than basic e-signatures by meeting the following criteria:

1) Signer Identity Verification: Certyfirma verifies the identity of each signer through official identity documents, ensuring that the person signing the document is who they claim to be.

2) Uniqueness: The signature is uniquely linked to the signer, using cryptographic techniques.

3) Data Integrity: Certyfirma guarantees that the signed document cannot be altered without invalidating the signature.

4) Audit Trail: Certyfirma provides a detailed audit log with timestamps and signer actions for each document, further ensuring trust and compliance.

These features ensure that Certyfirma's electronic signatures are legally binding, secure, and admissible in court, making them suitable for a wide range of professional and legal use cases.
