Chain of evidence
From sending to public verification
Send
You choose SES or AES per document and define the channels for the recipient in the editor.
Identify
With AES, the signer receives a 6-digit code by SMS or email before the signature is released.
Seal
After the final signature, the PDF is hashed and anchored with an RFC-3161 timestamp at an independent authority.
Verify
At any time, a copy of the PDF can be uploaded on /en/verify to check the hash and timestamp.
