Signature format

It may happen that the buyer wants a specific signature format to avoid having to materialize at the end of the chain.

Check if the buyer’s RC recommends or imposes a file format and signature standard.

There are 3 signature formats (CADES, PADES, and XADES):

  • The PADES format only applies to Acrobat documents, as an attached signature (only one file)
  • The CADES format applies to all formats (Word , Excel, Acrobat), in disjointed signature (2 files)
  • -Signature CAdES Signature PAdES

If you have subcontractors, make sure that the sequence of your successive signatures does not self-destruct. If a subcontractor has signed your documents in CADES (disjoint signature), all the following signatures must be in CADES, and otherwise you risk destroying the previous signatures!!

Note that if you sign a batch of Acrobat and Word or Excel documents with the PADES signature utility, the Acrobat files will be signed in PADES (attached signature), the others will cause an error. If necessary, make an Acrobat package and other files package.

Other notes associated with the theme of the signature:

  • Management of the co-signature of documents “pdf” with Acrobat Reader
  • Management of the co-signature of all file formats, with AWS-Signature
  • Installation procedure of the MV Java on your job (prior to AWS-Signature)
