Is your feature request related to a problem? Please describe.
I've been benchmarking file encryption for large files (2 GB) after making some file handling changes for the next release and noticed that most of the decryption time is due to File.ReadLines() being used to read the last line of the file to retrieve the original file name when the Anonymous Rename setting is enabled.
Describe the feature you'd like
In the next major release, I need to either find a faster method of reading this information, move the location of the original file name so that it's easier to access, or switch to a different method of storing the file name (e.g. how Cryptomator does it).
Cryptomator's method would probably be fastest as it requires no reading from the file at all, but I'd have to encrypt the file names and convert them to a safe format for the file system. The main limitations of this approach are that the user can't rename the files without losing the original file name and that handling long file names is problematic.
Why should this feature be implemented?
To speed up decryption of large and medium sized files.
