What is<\/span>
Qualified Timestamping?<\/h2>\n<\/div><\/div>\n<\/div>\n\n
\n

Timestamping is a process that cryptographically associates a real-time date and time with a document, event, or certain digitally performed operations such as sending an email or taking a photo.<\/p>\n

This association relies on a timestamping token, which acts as a digital seal, ensuring the integrity of the information by marking the exact moment of its creation or modification.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

Qualified Timestamping: <\/span>
how does it work?<\/h2>\n<\/div><\/div>\n\n

Step 1 \u2013 Transmission of hashes<\/strong>
The client\u2019s application connects to Evidency\u2019s qualified timestamping service via a secure API and automatically transmits the hash of the documents to be timestamped, without disclosing their content.<\/p>\n

Step 2 \u2013 Timestamping and sealing<\/strong>
Evidency associates each hash with an exact date and time to create a timestamp token, which is then sealed by Evidency.<\/p>\n

Step 3 \u2013 Return of tokens<\/strong>
The timestamp tokens are returned to the client.<\/p>\n

Step 4 \u2013 Subsequent verification<\/strong>
At any time, the token may be verified to demonstrate that the document existed at the stated time and that it has not been altered since.<\/p>\n<\/div><\/div>\n<\/div>\n\n

A timestamping solution
\n<\/span>designed for developers<\/h2>\n<\/div><\/div>\n\n

Evidency\u2019s qualified timestamping service is built on a sandbox, a REST API and dedicated SDKs, enabling straightforward integration into existing environments. These tools support a controlled and progressive implementation, regardless of your technical stack.<\/p>\n

Generation of a qualified timestamp token<\/h3>\n

With a single API call, you generate a timestamp token compliant with RFC 3161 and the eIDAS Regulation, ensuring a reliable date and the integrity of the timestamped data.<\/p>\n

Accelerate your development cycles<\/h3>\n

Code samples are available in the main programming languages to facilitate implementation and reduce development time. The sandbox allows integrations to be tested and debugged securely before deployment to production.<\/p>\n<\/div><\/div>\n\n
