In OpenKeychain, backups are encrypted using:
* AES-256 (because this is default for all encrypted files in OpenKeychain)
* Passphrase is based on 24 uppercase characters, separated with dashes into 4*6 character chunks. Thus, the passphrase is 27 characters long, example: ``ABCDEF-GHIJKL-MNOPQR-STUVWX``.
* Passphrase is generated by OpenKeychain and based on 24 uppercase characters, separated with dashes into 4*6 character chunks. Thus, the passphrase is 27 characters long, example: ``ABCDEF-GHIJKL-MNOPQR-STUVWX``.
* Possible combinations are: 26^24 = 2^112.8
* The backup file is ASCII Armored and a special header is added: ``BackupVersion: 1``
* OpenKeychain detects the header and shows an improved UI for input of the Backup Code
