What is a<\/span>
timestamping API?<\/span><\/h2>\n<\/div><\/div>\n<\/div>\n\n
\n

A timestamping API is an interface that allows an application to automatically request an electronic timestamping service.<\/span><\/p>\n

Its purpose is evidentiary. It serves to establish that a specific piece of data existed at a given date and time, and to verify at a later date that it has not been altered.<\/span><\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

Timestamping API
<\/span>How does it work?<\/h2>\n<\/div><\/div>\n\n

Step 1 \u2013 Access the sandbox<\/strong>
Test the timestamping API in a dedicated environment before deploying it to production.<\/p>\n

Step 2 \u2013 Integrate the API<\/strong>
Connect your application to the Evidency API using the technical documentation.<\/p>\n

Step 3 \u2013 Send your requests<\/strong>
Your application automatically sends the data hashes to be timestamped via the REST API.<\/p>\n

Step 4 \u2013 Receive the timestamp tokens<\/strong>
The qualified timestamp tokens are returned directly to your application.<\/p>\n

Step 5 \u2013 Go live<\/strong>
Once the integration has been validated, deploy the service to your production environment.<\/p>\n

<\/span>for developers<\/h2>\n<\/div><\/div>\n\n

Evidency offers two distinct environments: a sandbox, intended for testing, and the production environment, where the qualified timestamping<\/a> service is operated.<\/p>\n

The integration process is intentionally short: create an account, generate an API key, create a timestamping project, and then make calls to the service. The documentation also provides integration examples and a reference for the available endpoints.<\/p>\n<\/div><\/div>\n\n

FAQ<\/span>
Timestamping API<\/h2>\n<\/div><\/div>\n\n

What is the difference between a timestamp API and a simple computer timestamp?<\/h3>

A timestamp generated by an application records time-related information. A qualified electronic timestamp relies on a trusted third party and meets the requirements set forth in eIDAS. It thus benefits from the presumption defined in Article 41 of the regulation. <\/p>\n<\/div><\/div>\n\n

Is the Evidency API compatible with RFC 3161?<\/h3>

Yes. Evidency allows you to create a request that complies with the Time-Stamp Protocol (RFC 3161) and receive a corresponding timestamp response. <\/p>\n<\/div><\/div>\n\n

Should we send the document to Evidency?<\/h3>

For the timestamping service, the application can transmit the document\u2019s cryptographic fingerprint, rather than its content. RFC 3161 specifically provides for the timestamping of this cryptographic representation. <\/p>\n<\/div><\/div>\n\n

Can we test the API before it goes live?<\/h3>

Yes. Evidency offers a sandbox specifically designed for testing and validating integrations. Tokens created in this environment must not be used for legal purposes. <\/p>\n<\/div><\/div>\n\n

Why integrate an eIDAS-compliant qualified timestamp via API?<\/h3>

For a legal, compliance, or audit department, the issue is not simply a matter of knowing the date on which an IT system indicates that a file was created. A date embedded in a file\u2019s metadata can be altered.<\/p>\n

The eIDAS qualified timestamp operates on a different principle. Article 41 of the eIDAS Regulation provides that it is presumed to accurately reflect the date and time indicated, as well as the integrity of the data to which they relate. Furthermore, a qualified timestamp issued in one Member State is recognised as such in the other Member States.<\/p>\n

Article 42 requires, in particular, that the date and time be linked to the data in such a way that any alteration can be detected, and that they be based on a clock synchronised with Coordinated Universal Time (UTC).<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":246879322,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"class_list":["post-16102","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"\neIDAS-Qualified Timestamping API | Evidency<\/title>\n<meta name=\"description\" content=\"Integrate eIDAS-compliant time stamps into your applications using the Evidency API.
