This section provides examples of encryption headers.

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-Envel

ope-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

.
