+.SS "Global hash info table"
+There's no problem with using the same key for several purposes, as long
+as it's secret from all of your adversaries. Therefore, there is a
+global
+.B unihash_info
+table define, called
+.BR unihash_global .
+This initially contains information for a fixed key which the author
+chose at random, but if you need to you can set a different key into it
+.I before
+it gets used to hash any data (otherwise your hash tables will become
+messed up).
.SS "Theoretical issues"
The hash function implemented by

cryptographic security, which actually reduce the security of some
construction to the security of its components). It's just a fact.
