Hi Martin,
I have not found anyone that has done that before in Data3Sixty Analyze. However, you may be able to build a node that is based on the Python node. The Python gnupg package provides functionality to decrypt pgp-encrypted files, see here for an article that discusses how it is used in a standalone Python install:
https://stackoverflow.com/questions/11799071/decrypting-pgp-using-gnupg-in-python
The gnupg package would need to be installed so that the Python instance used by Data3Sixty Analyze could access the package.
For Windows, open a command window in Administrator mode and change directory to the directory containing the python executable, e.g. C:\Program Files\Data3SixtyAnalyze\platform\windows-x86-64\python
Then at the command prompt use the pip to install the package:
python -m pip install gnupg
Please note that third party Python packages are not part of the Data3Sixty Analyze product and are not covered by our support policy. The contents of the site-packages folder (e.g. C:\Program Files\Data3SixtyAnalyze\platform\windows-x86-64\python\Lib\site-packages) is not maintained when the Data3Sixty Analyze software is updated so you would need to re-install the gnupg package (and any dependent packages) after the install. Alternatively, you could try installing the package to a different directory outside of the application's installation directory using the --target option for pip, and adding the directory to the Python search path.
