Easy-to-use services
1 - Use of timestamping
To produce a timestamp, La Poste must either receive the file
or its digital hash. In return, you will receive a timestamp attestation (Digital Postmark) signed by La Poste.
This attestationcontains a timestamp token rfc 3161.
You may ask La Poste to safeguard the Digital Postmark.
You can also ask La Poste to verify a timestamp that has
already been produced, by either providing the Digital Postmark or
asking La Poste to retrieve it from its database.
In this case, you will be given the results of the
verification.
You can ask La Poste to send you the resultant verification attestation
or to safeguard it.
2 - Use electronic-signature validation
To verify an electronic signature, the relevant file must be sent to
La Poste accompanied by its electronic signature.
You will be given the result of this verification.
You can ask La Poste to verify the validity of the electronic certificate, to send
you the verification results signed by La Poste, and have it
safeguarded.
3 - Use of La Poste’s signature on a document
For a digital document to be given La Poste’s signature, the
relevant file or simply its hash must be transferred to La Poste.
In return, you will receive the electronic signature of the document
accompanied, if needed, by a Digital Postmark, signed by La Poste.
At your request, La Poste can safeguard the Digital Postmark.
4 - Use of evidence safekeeping
To access evidence held by La Poste, you can ask for the results of
previous queries for which La Poste was asked to safeguard the
findings. If you are registered and have clearance to make such a
request, you will be given the result of your query.
You can ask La Poste to send you a timestamp attestation of the result,
or have it held for safekeeping.
