Step 5. Encrypt Files
If you want your files to be encrypted before uploaded to the FTP server, before uploading (Step 4),
check the Encrypt box in the screen center. You will be prompted to choose an Encryption Key.
An encryption key is just like a password. The encryption process mixes it with the file content to make the file unreadable by others.
Each encryption key has a Key Name. The key name is not used in encryption, but it can give your a hint when you
decrypt the files.
TIPS: As you do with choosing a password, pick a strong key, and a name that is easy to remember but not related to the key itself.
