crypt_data() changes

[jimp]

Not really a "heads up", more of a "keep your eyes peeled" since it shouldn't be user-visible, but there are a couple changing coming to crypt_data():

• https://redmine.pfsense.org/issues/9420
• https://redmine.pfsense.org/issues/9421

These update the syntax to use options for the current (new) openssl version and improve the security a bit. Problem is that some of the new options won't work with older backups, but the new code detects that and tries the old options in those cases.

So you should not see any problems with making or restoring encrypted backups, or using ACB to make new or read old backups.

It should all be seamless and compatible. If not, let me know.
