Data is encrypted in VSys using Advanced Encryption Keys. These represent the PGP "public" keys. Create new encryption keys with the Advanced Encryption Keys Setup tool.
Right-click on the list and select Add encryption key.
Give that key a description, and make it one that's useful to you: you'll see that description in the various setup tools and when being prompted for a decryption key.
Save the decryption key (the "private") key to two separate disk files, then store those in a safe place. NOTE: A "safe place" is not on your desktop, or on a file share, or anywhere other than an external USB key, both of which are then stored in locked, protected places!
