When i open the eEvid PDF evidence, Adobe Reader gives me a message about the signature: 'At least one signature has problems'. Can I trust eEvid's digital signature?

Sure you can!

The root digital certificate used to protect the data included in the eEvid.Cert evidence, is issued by an accreditted digital signature provider. Adobe, however, does not include, as trusted certificates, all root certificates there exist worldwide.

When you receive a signed document, you may want to validate its signature(s) to verify the signer and the signed content. Depending on how you have configured your application, validation may occur automatically. Signature validity is determined by checking the authenticity of the signature’s digital ID certificate status and document integrity:

  • Authenticity verification confirms that the signer's certificate or its parent certificates exist in the validator’s list of trusted identities. It also confirms whether the signing certificate is valid based on the user's Acrobat or Reader configuration.
  • Document integrity verification confirms whether the signed content changed after it was signed. If content changes, document integrity verification confirms whether the content changed in a manner permitted by the signer.

If you don't fel comfortable with the Adobe warning message, you need to trust the certificate within your computer system. In order to do so, please follow the instructions provided by Adobe.

Trust us: this Adobe warning has nothing to do with the certificate's integrity and real trusty.
