Here's a patch based on the original description. I've ignored #1 as clearly too much has changed since then for non-patch code to be useful.

Here's an updated patch that works with webform 7.x-4.2
It's all minor changes to use webform's new structure omitting the [value] from the array.

Re-uploading patch with diff. Also deleted extra debug line I forgot.

@jcuna

I see in your patch there is a function that is called webform_encrypt_webform_submission_load.
This function does not exist in the original 7.x-1.x branch http://cgit.drupalcode.org/webform_encrypt/tree/webform_encrypt.module?h...

If your code is a working version than you are missing code from the last patch.

I did notice that the patch file from comment #3 is not an actual patch and there is data in there that you are referencing in your last patch.

If this is the case then please create a patch that is a diff between 7.x-1.x and your current code that is working. If you need help in doing so please let me know.

I need this for a client and am glad to help.

Hey FatGuyLaughing

My apologies, didn't even remembered that I had patched the module before as I was having issues loading the encrypted data. The patch I applied never made it to the 1.x branch. There was an issue where the decryption was run while a submission was being rendered, as opposed to loading.

Here's the post for that issue.

https://www.drupal.org/node/1433524

+1 for #2. Requires that you use the AES module (or at least not the default).

Hi jcuna!
Thanks for your workaround, it helped me a lot. What I did is just remove dpm() and brought better formatting to it.

Again Thanks.

Why are you not publishing it as a new release? Would be helpful for several people. Best regards!

Hi,

I had some issues with some of these patches on the 7.x-1 branch. I have created a new patch which includes a check for the webform version so this can be used on both webform 3 and 4. Same changes as #2 but includes a check in the install hook for the webform version number, stores this in a variable and uses that in presave hook to save i the correct format.

Re: #13-14
The approach used to determine the webform version isn't recommended. What happens if webforms is updated? This is a perennial issue for drupal modules. The recommended approach is to tie versions of modules to other versions of modules. In this case, tie 1.x of webform_encrypt to 3.x and 2.x to 4.x (for example). It might also be a good time to add support for encrypt 2.x: #2325353: Compatability with Encrypt 7.x-2.x.

I agree with #15, #14 is not the best approach. A webform encrypt 2.x branch would be the best way forward with this tied to encrypt 2.x and webform 4.x. There are also plenty of other patches floating around that can be included, this is a useful module that needs to be kept up to date.

How do I get Webform Encrypt to work with the latest Drupal 7 modules?

I am using:
* Drupal 7.43
* Webform 7.x-4.12
* Encrypt 7.x-2.3

If there isn't a released version, then what patches do I need to apply?

thx

wavesailor, see https://www.drupal.org/node/2325353#comment-11331777

A re-roll of #14. Though I agree with the version bump to just support webform 4 only.

This has been released in 7.x-1.3 version.
