+SignatureEd25519
+^^^^^^^^^^^^^^^^
+
+``SignatureEd25519`` defines an Ed25519 public key signature that is calculated over the "signed portion" of an Interest or Data packet.
+This signature algorithm is defined in `RFC 8032, Section 5.1 <https://datatracker.ietf.org/doc/html/rfc8032#section-5.1>`__.
+
+* The TLV-VALUE of ``SignatureType`` is 5
+* ``KeyLocator`` is required
+
+::
+
+    SignatureValue = SIGNATURE-VALUE-TYPE
+                     TLV-LENGTH
+                     64OCTET ; == Ed25519{Data signed portion}
+
+    InterestSignatureValue = INTEREST-SIGNATURE-VALUE-TYPE
+                             TLV-LENGTH
+                             64OCTET ; == Ed25519{Interest signed portion}
+
+This type of signature, if verified, provides very strong assurances that a packet was created by the claimed producer (authentication/provenance) and was not tampered with while in transit (integrity).
+The ``KeyDigest`` option in :ref:`KeyLocator` is defined as the SHA-256 digest over the DER encoding of the ``SubjectPublicKeyInfo`` for an Ed25519 key as defined by `RFC 8410, Section 4 <https://datatracker.ietf.org/doc/html/rfc8410#section-4>`__."
