is LUKS-2 support planned?

[dimadenisjuk]

Will you merge your project with modern cryptsetup version?
It very difficult to use it without LUKS-2 support! But I can't merge code because don't know how.
I only wrote PKGBUILD for ArchLinux and added it to AUR repository (https://aur.archlinux.org/packages/cryptsetup-deluks/).

Well, development is stopped so there is no plan to merge upstream commits.

I don't see the need to support LUKS2 unless you're using system encryption. DELUKS is just another (encrypted) header format. It is not LUKS1, it is based on LUKS1. cryptsetup-deluks doesn't need to replace cryptsetup unless you're using system encryption.

If you're NOT using system encryption, you can safely compile cryptsetup-deluks to some binary file, for example named cryptd like in the documentation, and run it from the command line to encrypt/decrypt a drive or partition, and it works fine even on recent O.S.

If you're using system encryption, replacing system cryptsetup with the DeLUKS version and replacing grub with the DeLUKS doesn't work on recent O.S. This is required for system encryption.
