This article describes how to import PGP keys to Symantec Encryption Desktop (previously PGP Desktop) for Mac OS X.
PGP keys can be exported from PGP Desktop as .asc files. This is a good way to back up your keys or exchange your public keys with others. If you have an .asc file on your system that includes a PGP key that you want on your keyring, you can import it from the Finder.

Tip: You can also import a key by selecting File > Open and browsing to the desired .asc file.
Add PGP Public Keys to Your Keyring
PGP Desktop stores your PGP keys on keyrings; you always have one private keyring (.skr) file that holds private keys and one public keyring (.pkr) file that holds public keys.
If you have a public keyring file (not your active public keyring file) on your system that holds keys you would like to add to your active keyring, you can add them from the Finder.
To add PGP public keys from a keyring file in the Finder
Tip: In the Finder, double-click the PGP public keyring (.pkr) or PGP private keyring (.skr) file. The new keyring will appear in PGP Desktop, below your existing keyrings, as "PGP Public Keyring."
