Verify Account Certificate in OBS-e3

[Arielpetit]

Description

We need to implement a functionality to verify the validity and integrity of the account certificate to ensure secure communications and data integrity. The verification process should check the authenticity and trust chain of the certificate.

Acceptance Criteria

• The certificate's signature should be validated against the trusted certificate authority (CA).
• The certificate's key usage must align with the intended purpose (e.g., digital signature, encryption).
• Ensure the certificate is correctly linked to the account and valid for the intended use case.
• If the certificate is invalid, appropriate error handling and feedback should be provided.
