• Adobe Reader.

Delivery methods

How password-based encryption should occur with external contacts depends on the delivery method. Currently there exist the following three delivery methods:

• Z1 WebSafe: Instead of by e-mail, the message is exchanged over a web interface call “Z1 WebSafe”. For the user Z1 WebSafe feels just like a “secure webmailer”.
• Z1 KickMail: The message is sent as an encrypted HTML attachment by e-mail. The decryption occurs online with help from a web interface.
• Z1 KickMail-PDF: The message is sent as an encrypted PDF attachment by e-mail. Decryption occurs at the recipient's client.
