 ## hybrid post quantum cryptography
 
+Hybrid cryptographic constructions rely on a classical public key
+primitive and a post quantum public key cryptographic primitive, namely:
+
 * hybrid KEMs
 * hybrid NIKEs
 * hybrid signature schemes
 
+Are main contributions besides a generic NIKE interface and NIKE
+combiner is:
+
+1. an implementation of a secure KEM combiner that can combine an arbtrary
+number of KEMs.
+2. a "NIKE to KEM adapter" which is really an ad hoc hashed elgamal construction
+
+If you want a well known hybrid KEM that has a paper about it then maybe
+Xwing is the KEM you are looking for. Otherwise you can construct your own
+using our secure KEM combiner and or NIKE to KEM adapter.
