 choice for algorithm implies the implementor should also choose the P256 public

+## UDS certificates
+
+As noted in the section [General approach](#general-approach), the UDS\_pub may
+be authenticated by an OEM using an x.509 certificate chain. Additionally,
+[RKP Phase 3](#phases) depends on the chip vendor signing the UDS\_pub and
+issuing an x.509 certificate chain. This section describes the requirements for
+both the signing keys and the resulting certificate chain.
+
+### X.509 Certificates
+
+X.509v3 public key certificates are the only supported mechanism for
+authenticating a UDS\_pub. Certificates must be formatted according to
+[RFC 5280](https://datatracker.ietf.org/doc/html/rfc5280), and certificate
+chains must satisfy the certificate path validation described in the RFC. RFC
+5280 covers most requirements for the chain, but this specification has some
+additional requirements that must be met for the certificates:
+
+*   [`BasicConstraints`](https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.9)
+    *   All CA certificates must include this as a critical extension.
+    *   `pathLenConstraint` must be set correctly in each CA certificate to
+        limit the maximum chain length.
+    *   `cA` must be set to true for all certificates except the leaf
+        certificate.
+    *   `BasicConstraints` must be absent for the leaf/UDS certificate.
+    *   Consider the chain `root -> intermediate -> UDS_pub`. In such a chain,
+        `BasicConstraints` must be:
+        *   `{ cA: TRUE, pathLenConstraint: 1}` for the root certificate
+        *   `{ cA: TRUE, pathLenConstraint: 0}` for the intermediate certificate
+        *   Absent for the UDS certificate
+*   [`KeyUsage`](https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.3)
+    *   All certificates in a UDS certificate chain must include this as a
+        critical extension.
+    *   CA certificates must set `KeyUsage` to only `keyCertSign`.
+    *   The UDS certificate must set `KeyUsage` to only `digitalSignature`.
+
+### Supported Algorithms
+
+UDS certificates must be signed using one of the following allowed algorithms:
+
+*   `ecdsa-with-SHA256`
+    ([RFC 5758](https://www.rfc-editor.org/rfc/rfc5758#section-3.2))
+    *   Note: this algorithm is only usable with ECDSA P-256 keys
+*   `ecdsa-with-SHA384`
+    ([RFC 5758](https://www.rfc-editor.org/rfc/rfc5758#section-3.2))
+    *   Note: this algorithm is only usable with ECDSA P-384 keys
+*   `id-Ed25519` ([RFC 8410](https://www.rfc-editor.org/rfc/rfc8410#section-3))
