[RFD] Common userspace tool for fscypto

[Richard Weinberger]

Hi!

Since file level encryption has more than one user, currently ext4, f2fs and soon ubifs
it would be nice to have a single tool to control fscrypto from userspace.

For ext4 we have already at least two tools, one as part of e2fsprogs and another
one on github[0]. IMHO the latter one is much more user friendly and intuitive to use.
I as unable to find the userspace tool for f2fs.

That said, what about implementing such a tool as part of util-linux to control
fscrypto? We (David and I) would volunteer.

Thanks,
//richard
