Your documents display the green checkmark "Signature is VALID" in Adobe Reader. Instant worldwide recognition, no configuration needed.
Content is never read by SE. Your files stay in your browser. Only a cryptographic hash is used for signing.
A document signed today remains legally valid over time. Proof of validity is embedded in the PDF.
Signature history, precise timestamps, signer identity. Everything is embedded directly in the document.
Text fields, dropdown lists, multiple selections. All Adobe form fields are natively supported.
Any alteration after signing is automatically detected and flagged in red by Adobe Reader. Impossible to falsify.
Unlike other solutions, your files stay in your browser. Content is never read by Secure Exchanges. We simply don't have access to it.
Only a cryptographic hash (SHA-512) is used to generate the certified signature. The result: a globally recognized signature with zero compromise on confidentiality.
