- The decryption key sits after the link’s #, which browsers do not send to the server; an emailed link can still carry that key.
Field notes
The compose interface includes text, attachments, recipient selection, optional passwords, and expiry choices ranging from minutes to days. The page says the key is placed after a # in the link, so the browser does not send that part to the server; however, an invitation email can carry the access link and key. Account features include saved conversations and read-status checks.
