# nothing one can do and the result appears optimal. CCM result is
# identical to CBC, because CBC-MAC is essentially CBC encrypt without
# saving output. CCM CTR "stays invisible," because it's neatly
-# interleaved wih CBC-MAC. This provides ~30% improvement over
+# interleaved with CBC-MAC. This provides ~30% improvement over
# "straightforward" CCM implementation with CTR and CBC-MAC performed
# disjointly. Parallelizable modes practically achieve the theoretical
# limit.
