I just started using eM client with my gmail account. How do I figure out what my PGP public key is? Thanks!

PGP public key

If you go to Menu > Tools > Settings > Signing and Encryption > Certificates and Keys, if you do not already have a key you can create one.

Once you have a key pair, you can export your public key by clicking on the settings cog next to your key and choosing Export > Export PGP Public Key.

In Menu > Tools > Settings > Signing and Encryption > Account policies, you can also choose to have the public key attached to all outgoing emails.
