      How do I know if I am using the right files?

      When preparing a document in Mifiel, it is possible to specify that it must be signed using an e.firma belonging to a particular RFC. This puts a lock that prevents you from using the e.firma of a different RFC to sign it.

      It is therefore necessary that you use the .cer and .key files that belong to the same e.firma and whose RFC matches the one indicated by the document manager (the person who requested your signature).

      Common errors

      The possible errors that can prevent you from signing a document that was created in this way are the following:

      1. A certificate belonging to a different RFC than the one specified by the document manager was preloaded or you selected it
      2. The files you selected do not belong to the same e.firma
      3. The RFC specified by the document manager does not correspond to your RFC

      A certificate belonging to a different RFC than the one specified by the document manager was preloaded or you selected it

      For example, you were asked to sign with the files corresponding to the RFC of your company and you are trying to sign with the files corresponding to your personal RFC.

      This can happen because you have several e.firmas, for example, yours as an individual and other(s) as a legal entity since you are the legal representative of your company.

      If this happens and you have access to the e.firma you are being asked to sign with, just click on the option "Select another" to select the correct certificate and continue the signing process.

      The files you selected do not belong to the same e.firma

      How to identify the correct files?

      Generally, e.firma file names contain the RFC to which they belong. So the first step is to check that both files you are using (.cer and .key) contain the same RFC specified by the document manager.

      The RFC specified by the document manager does not correspond to your RFC

      This can occur due to the following reasons:

      1. The manager made a mistake when typing your RFC. For example, your RFC is CAGI870912SX1 and the manager specified CAGI870912SX2.
      2. The manager confused the RFCs and emails of different signers. This means that you received the invitation intended for another person.

      In any of these cases, please contact the document manager (the person who requested your signature) so they can resolve it.
