+How to check the testvectors included in ./lrw-32-aes?
+
+Simply execute them; lrw-32-aes is a bash script that calls some functions
+in testvector.fun. Tools like dm-setup and some hex utitities will be used
+to check them through the usual kernel interface. You can add testvectors of
+other modes in an analogous manner.
