3.HOW TO SIGN AND STAMP

Attention:

  • To use this function, the user must have a digital signature and a batch of time stamps.
  • Users without a digital signature and/or a batch of time stamps can purchase them from our Online Shop.

Once a file has been selected, this function allows a signature and time stamp to be applied in a single session.
Files signed and stamped using this process will be generated in CADES-T format (stamped file.pdf.P7M).
In CADES-T format (default), the stamp is associated with the individual signature and CANNOT be separated.

To apply a digital signature and time stamp to a document, proceed as follows:

  • Click Sign and Timestamp in the programme
  • Select a destination folder for the signed file, then click OK

  • Proceed with the signature operation by pressing Yes.

  • Enter the PIN of the digital signature device and click OK.

4. HOW TO SEPARATE STAMP

This functionality allows the time stamp to be separated from a .TSD (TimeStamped-Data) file type.

N.B: this operation is only possible for files signed in .p7m format


4.1 Signing a document in .p7m format

Upload the file to be signed to the programme and click Sign.

N.B: The FirmaCerta software allows users to sign any type of file in CAdES format (i.e. .p7m); in the case of PDF or XML files only, a message will appear on the screen asking whether to sign in .p7m format or maintain the original format.

 

Once the user clicks "sign", a window will appear asking them to specify the format to use to sign the document.

Press No to apply a CAdES signature, in .p7m format.
