+====== Cryptographic Material ======
+[[public:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]]
+===== Discussion =====
+Cryptographic Material supports cryptographic operations and the establishment or maintenance of cryptographic relationships.
+Cryptographic Material includes symmetric keys, private keys, public keys, certificates, key-encryption keys, seeds, salts, initialisation vectors, nonces, shared secrets, and related cryptographic parameters.
+Not all Cryptographic Material requires [[public:99_annexes:annex-b-terms-and-definitions:c:confidentiality|Confidentiality]]. Public keys and certificates ordinarily require [[public:99_annexes:annex-b-terms-and-definitions:i:integrity|Integrity]] and authenticity without secrecy. Private keys and shared secrets require confidentiality in addition to integrity and authenticity.
+The applicable protection depends upon the material’s purpose, classification, [[public:99_annexes:annex-b-terms-and-definitions:l:lifecycle|Lifecycle]] state, and exposure risk.
+===== Definition =====

+===== Note =====
+Cryptographic Material remains distinct from a [[public:99_annexes:annex-b-terms-and-definitions:c:credential|Credential]]. Cryptographic Material supports cryptographic processing. A Credential represents an [[public:99_annexes:annex-b-terms-and-definitions:i:identity|Identity]] or authority claim used in [[public:99_annexes:annex-b-terms-and-definitions:a:authentication|Authentication]] or [[public:99_annexes:annex-b-terms-and-definitions:a:access_control|Access Control]]. A single artifact, such as a digital certificate, satisfies both definitions when an authentication process uses it to establish identity.
+Cryptographic Material requires lifecycle controls addressing generation, acquisition, distribution, storage, access, use, rotation, revocation, expiration, archival, recovery, and destruction.
+Records concerning protected Cryptographic Material use protected references, identifiers, digests, or redacted representations to preserve [[public:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] and [[public:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] without exposing the protected data.
+===== Example =====
+A private key and its associated public-key certificate used by a [[public:99_annexes:annex-b-terms-and-definitions:n:node|Node]] for mutual TLS constitute Cryptographic Material. The certificate also constitutes a Credential when the authentication process uses it to establish the Node’s identity.
