Importing keys into the PGP Trust Store

PGP Trust store contains trusted public keyrings.
You can import an existing public keyring going to Setup → PGP Trust Store → Import.

Warning!

A keyring can either be in an armor or binary format, and the system will automatically self-detect it.

To view, delete, or export your key or certificate, click the 3-dot icon on the right of each entry.

As for the PGP Key Store, also in the PGP Trust Store you can see the sub-key of each master key and export a key pressing the button on the left of the screen.
