Hi Heiko,
Split key (0x10) looks like a good way to implement separation of duties
(where multiple people are needed to use the key). I don't think this is
possible in OpenPGP now.
This was one reason to create DKGPG: https://www.nongnu.org/dkgpg/
Currently, there are some efforts at NIST on threshold cryptography:
https://csrc.nist.gov/projects/threshold-cryptography
That's intriguing, thanks for bringing this up, I'll definitely check this out
as this is something I've been thinking of for quite some time.
Kind regards,
Wiktor
