e-Signing

I received a ZIP file after using e-Signing, what is it?

• The original file that was signed:
  It is of the utmost importance that the relation between the original file and the signature is maintained and that the original file is not altered in any way (even when only one character in the file is changed, the signature becomes invalid). By including the original file in the signature archive, optimal conditions are provided to live up to these requirements
• The signature itself in a XAdES-X-L format:
  This is the signature itself. As a user you do not have to open this file. During the verification, the e-Signing service will interpret this file and all information it contains that allows to ensure that all elements of the signature are valid. You can perform this verification free of charge using the Certipost e-Signing verification service
• A read me PDF file:
  This file is not required for the legal value of the signature, but gives some explanation about the signature archive, what its value is and how the Verifier can validate it
