This module creates the ability to encrypt fields/components from the Webform module. Each Webform component can be marked as "Encrypted" and every time a user submits the webform, the encrypted value for that component will be saved instead of the original value.
Encryption is provided by the Encrypt module.
The 6.x branch of this module requires Webform 3.x and Encrypt 1.x. It will not work with older versions of Webform, or the release candidate of Encrypt (2.x) yet.
