there are competitors which you can search on alternativeto.
there are open source alternatives.
BC's file based method is more usable than other vault based method.
But I am also concerned for close source vs open source.
so for really personal secret I will use an open source alternative.
But for media files (especially that originally download from youtube),
I will use BC as it allow partial decryption while playing.
the competitor CTMT need to decrypt a 5GB file before playing.
so BC is more usable. but others are trustable.
