7.13. Encrypt / decrypt using OpenPGP / GPG¶
The openpgp event handler can be configured to encrypt or decrypt files using the OpenPGP standard (tools like PGP or GPG).
All files with the .pgp or .gpg extensions are decrypted, all the other files are encrypted.
Encrypted files will have the .pgp extension appended to their filename.
The handler can be associated with events containing a list of files. It will try to handle each file associated with the event and will stop at the first failure.

When you want to have it triggered for all the events, excepting a few events you should prefix each event id with the exclamation mark (!).
Leave it empty to handle all events.
Note
Combining the two methods is not supported as the same result can be achieved by allowing only the desired events, all the others will be ignored.

3.22.0
- Description:
Comma separated definition with the name of attribute data member and the targeted matching expression.
Data member names are configured with insensitive cases.
For more details about the available expressions see the matching expression documentation.
The following example will extract the value to be matched/filtered from the path data member of the event. The extracted value is then matched against the
*/folderA/*globbing expression:[event-handlers/b904ed23-a234-4ccf-8abd-edcae4d3324f] data_filter = path, */folderA/*
See the usage instructions for more operational details.
You can filter based on multiple data members using multiple rules. Each rule is defined on a separate line.
In the following example, events are triggered only if they are uploaded into the directory named
reports-Awith a size of 0 bytes (empty file):[event-handlers/b904ed23-a234-4ccf-8abd-edcae4d3324f] data_filter = path, */reports-A/* size, 0
Leave this configuration empty to not filter based on the event's attached data, and handle events regardless of their data attributes.
