 ## SerializeKey and DeserializeKey
 
 The serialization routine for keys simply concatenates the fixed-length public or private keys of the component signatures, as defined below:
+~~~
+Composite-ML-DSA.SerializeKey(key) -> bytes
+
+~~~
+{: #alg-composite-serialize title="Composite SerializeKey(pk)"}
+
+Deserialization reverses this process, raising an error in the event that the input is malformed.
