Kenny Root 1137341885 Throw exception on odd length Signatures
The old version of this code would silently truncate odd-length
Signatures. However, this masks some bugs. Add a throw of
IllegalArgumentException so users can easily see where they're getting
bad input for Signatures.

Also, go through the existing code and catch this exception or
pre-check the input strings so system_server doesn't crash later.
