Patrick Steinhardt did the original work, importing PHC Argon2id
into GRUB; this fact was unintentionally excluded from the
Canoeboot documentation.
Ax333l imported it into GRUB on the AUR, and Nicholas Johnson later
rebased it for GRUB 2.12, for use by the Libreboot project which was
then adapted for use in the Canoeboot project.
Credit where credit is due. The principle of the matter is that
I apologise for this oversight. It has now been corrected.
