Abstract Abstract
This document updates PKINIT, as defined in RFC 4556, to remove This document updates PKINIT, as defined in RFC 4556, to remove
protocol structures tied to specific cryptographic algorithms. The protocol structures tied to specific cryptographic algorithms. The
PKINIT key derivation function is made negotiable, the digest PKINIT key derivation function is made negotiable, the digest
algorithms for signing the pre-authentication data and the client's algorithms for signing the pre-authentication data and the client's
X.509 certificates are made discoverable. X.509 certificates are made discoverable.
