Bonjour. J'ai installé ODK Central sur un serveur Ubuntu 18.04. J'arrive l'utilisé sans problème. J'ai chiffré un projet avec une clef personnel. Mon problème est de savoir comment déchiffrer les données pour les afficher avec une api en utilisant la clef sécrète??

When a form is encrypted you will no longer be able to connect to the data over OData. More details are in the [docs](https://docs.getodk.org/central-encryption/).

> - Encrypted submissions will appear only as metadata records over OData. Metadata like the submitter and the submission date will be available, but none of the actual data from the form will appear.

If you enabled project managed encryption it should have shown this warning:

If you used self-supplied key encryption with the public key embedded into the XForm itself, decryption is possible only with the private key, and only through Briefcase.
