			Abstract
			The IANA registry named "Hypertext Transfer Protocol (HTTP) Digest
			Algorithm Values" defines values for digest algorithms used by
			Instance Digests in HTTP. Instance Digests in HTTP provide a digest,
			also known as a checksum or hash, of an entire representation of the
			current state of a resource. This draft adds new values to the
			registry and updates previous values.
