This is 2020. Issue #9245

Fix copyright message years to reflect BSDP -> ESF -> Netgate

Use new/stronger openssl options for crypt_data(). Fixes #9421

read old style data from previous encryption runs (e.g. old encrypted
backups, ACB entries, etc)

Better error handling and suppression to prevent issues like #9421.
