You can apply a hashing algorithm to a string that contains spaces. The spaces are very much relevant.

In MD5 "String with spaces" yields eab431cd212fb8b5ae223acbcfe58cca

"Stringwithspaces" gives 3cd297b2d7e48709d92890f88abdde0a

I meant the hashes themselves wouldn't have spaces, therefore any odd database storage requirement wouldn't matter.
