vnd(4) works well, as you note, but is indeed not very portable.
You don't say what 'several' means,
Hopefully OpenBSD, linux, I plan to play wth FreeBSD, and every once
in a while I do end up on Windows.
but I believe you could mount a
filesystem on a vnd under Linux after you have called losetup with a
suitable offset (i.e., bypassed the disklabel).
Ah, now that is an interesting information. Could it be also possible
the other way around? Create an encrypted file-partition in linux, and
mount (and decrypt) it using vnd?
cfs might be portable - though it is not very secure.
Yeah, that thought passed my mind, but I'd rather first consider other
options as IIRC this project seems to be unmaintainded.
Finally, tar and gpg offer a solution... as long as you are careful when
untarring.
Yes, need to wipe files and free space afterwards. So, would prefer a
filesystem level encryption. But, that's also an option.
Also there's a similiar option to gpg-zip or gpg+tar, which is 7zip
wit it's encryption. Though someone would have to port it ;)
