PGP Encryption Utilities

Hello

We have tries this out in a Sandbox app in our Dev environment and are seeing the following:

In the logs we are seeing this error:

11:39:29.908 [Appian Work Item - 5968 - WorkID 298 - execution00 - process 19235 - model 5178 : UnattendedJavaActivityRequest] ERROR com.vuram.plugins.ps.PGPEncryptFileSmartService - Error encrypting file with PGP
org.bouncycastle.openpgp.PGPException: unable to set up ephemeral keys: unknown ParameterSpec

This error message isn't helping identify the root cause of the error. Are you able to provide some indication as to what the problem is?

More worrying is that the process does not catch this error and continues on to completion, giving a falsely positive indication that the process has completed successfully. Whilst a fix to the root cause is required, we cannot use this plug-in if we cannot be sure that the process will not stop when errors are encountered. So in actual fact a fix to both issues is required for us to be able to use this.

Thank you. The problem was that the process model was created before plugin upgrade. After upgrading plugin the smart service node icon deceivingly updated too but it wasn't actually the updated smart service. Solution was to remake the node anew.

Hi Ladislav Jaroscak ,

Kindly use the new version of the smart service instead of the deprecated version(Refer to the screenshot below).

Regards,
Snehasri S.

Hi Ladislav,

Could you share the tomcat-log file after initiating the process model again. This might be helpful for us to know further on the issue.

Hi Ladislav,

Hello,

when using encryption smart service we keep getting error message

"In order to access this method, this Document needs to be retrieved via ContentService.download()"

The output document shows in appian designer, has corresponding extension, but is of size <1KB (0 probably) and its not downloadable. In PM, when using PV to store this as an output of the smart service into, the PV ends up with no value.

Any sugggestion what could be going wrong?
