Signature Validation

Objective:

Validate the authenticity and integrity of digital signatures, including Long-Term Validation (LTV) or Time-based validity.

Guidelines:

• Implement validation mechanisms to verify digital signatures against trusted certificates.
• Enable Long-Term Validation (LTV) in your EDS to ensure that signatures remain valid even after the signing certificate expires.
• In case limited time validity is applied, the system should be able to check the signature validity type, and provide an understandable message to the user in case the signature validity time is exceeded.
