Encryption Headers
The following table displays the encryption headers that you can add to messages.
MIME Header |
Description |
Value |
---|---|---|
|
Indicates whether to enable a secure reply for the message and displays the Reply button in the message bar. This header adds an encryption setting to the message. |
A Boolean for whether to display the Reply button. Set to true to display the button. The default value is false. |
|
Indicates whether to enable secure “reply all” for the message and displays the Reply All button in the message bar. This header overrides the default profile setting. |
A Boolean for whether to display the Reply All button. Set to true to display the button. The default value is false. |
|
Indicates whether to enable secure message forwarding and displays the Forward button in the message bar. This header overrides the default profile setting. |
A Boolean for whether to display the Forward button. Set to true to display the button. The default value is false. |
|
Indicates whether to enable read receipts. The sender receives a receipt when recipients open the Secure Envelope. This header overrides the default profile setting. |
A Boolean for whether to send a read receipt. Set to true to display the button. The default value is false. |
|
Defines a Registered Envelope’s expiration date before sending it. The key server restricts access to the Registered Envelope after the expiration date. The Registered Envelope displays a message indicating that the message has expired. This header adds an encryption setting to the message. If you use Cisco Registered Envelope Service, you can log in to the website at http://res.cisco.com and use the message management features to set, adjust, or eliminate the expiration dates of messages after you send them. |
A string value containing relative date or time. Use the +HH:MM:SS format for relative hours, minutes, and seconds, and the +D format for relative days. By default, there is no expiration date. |
|
Defines the Registered Envelope’s “read by” date before sending it. The local key server generates a notification if the Registered Envelope has not been read by this date. Registered Envelopes with this header do not work with Cisco Registered Envelope Service, only a local key server. This header adds an encryption setting to the message. |
A string value containing relative date or time. Use the +HH:MM:SS format for relative hours, minutes, and seconds, and the +D format for relative days. By default, there is no expiration date. |
|
Indicates whether to disable the decryption applet. The decryption applet causes message attachments to be opened in the browser environment. Disabling the applet causes the message attachment to be decrypted at the key server. If you disable this option, messages may take longer to open, but they are not dependent on the browser environment. This header overrides the default profile setting. |
A Boolean for whether to disable the decryption applet. Set to true to disable the applet. The default value is false. |
|
Indicates whether to send JavaScript-free envelopes. A JavaScript-free envelope is a Registered Envelope that does not include the JavaScript that is used to open envelopes locally on the recipient's computer. The recipient must use either the Open Online method or the Open by Forwarding method to view the message. Use this header if a recipient domain's gateway strips JavaScript and makes the encrypted message unopenable. This header adds an encryption setting to the message. |
A Boolean for whether the JavaScript applet should be included or not. Set to false to send a JavaScript-free envelope. The default value is true. |
|
Indicates whether to allow envelope-specific key caching for the offline opening of envelopes. With envelope key caching, the decryption key for a particular envelope is cached on the recipient’s computer when the recipient enters the correct passphrase and selects the “Remember the password for this envelope” checkbox. After that, the recipient does not need to enter a passphrase again to reopen the envelope on the computer. This header adds an encryption setting to the message. |
A Boolean for whether to enable envelope key caching and display the “Remember the password for this envelope” checkbox. The default value is false. |
