* Save encrypted files in binary formatplumbeo2022-05-041-11/+36
| | | | | | | | | | | | | Default to the more space-efficient binary encoding for newly encrypted files instead of the traditional base64 encoding, eliminating the 33% overhead. The new option 'encryption.use_legacy_encoding' allows to force the legacy encoding format if needed. Files encoded in the old format remain readable. Based on https://github.com/owncloud/encryption/pull/224 and https://github.com/owncloud/core/pull/38249 by karakayasemi. Signed-off-by: plumbeo <plumbeo@users.noreply.github.com>

* Format control structures, classes, methods and functionChristoph Wurst2020-04-101-8/+3
| | | | | | | | | | | | | | | To continue this formatting madness, here's a tiny patch that adds unified formatting for control structures like if and loops as well as classes, their methods and anonymous functions. This basically forces the constructs to start on the same line. This is not exactly what PSR2 wants, but I think we can have a few exceptions with "our" style. The starting of braces on the same line is pracrically standard for our code. This also removes and empty lines from method/function bodies at the beginning and end.
