This section provides examples of encryption headers.

To send a Registered Envelope with envelope key caching enabled, insert the following header into the 
message:

X-PostX-Remember-Envelope-Key-Checkbox: true

The “Remember the password for this envelope” check box is displayed on the Registered Envelope.

To send a Registered Envelope that is JavaScript-free, insert the following header into the message:

X-PostX-Use-Script: false

When the recipient opens the securedoc.html attachment, the Registered Envelope is displayed with an 
Open Online link, and the Open button is disabled.

X-PostX-Use-Script

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

.

X-PostX-Remember-Envelope

-Key-Checkbox

Indicates whether to allow 
envelope-specific key caching for 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 password and selects 
the “Remember the password for this 
envelope” check box. After that, the 
recipient does not need to enter a 
password 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” check box. The 
default value is 

false

.
