Diffie-Hellman Proof-of-Possession Algorithms
Abstract
This document describes two methods for producing an integrity check
value from a Diffie-Hellman key pair and one method for producing an
integrity check value from an Elliptic Curve key pair. This behavior
is needed for such operations as creating the signature of a Public-
Key Cryptography Standards (PKCS) #10 Certification Request. These
algorithms are designed to provide a Proof-of-Possession of the
private key and not to be a general purpose signing algorithm.
This document obsoletes RFC 2875.
