Abstract
This document describes a protocol whereby a user can acquire
cryptographic credentials (e.g., private keys, PKCS #15 structures)
from a credential server, using a workstation that has locally
trusted software installed, but with no user-specific configuration.
The protocol's payloads are described in XML. This memo also
specifies a Blocks Extensible Exchange Protocol (BEEP) profile of the
protocol. Security requirements are met by mandating support for
TLS and/or DIGEST-MD5 (through BEEP).
