Loop to length($_) - 1. The second argument to substr() is an *offset*. If there are 32 characters in the string, the offsets run from 0 to 31.

That may not solve the entire issue, because I'm not sure if you get carriage returns when reading in a file on Windows. If you're not on Windows, it doesn't matter.

Either way, you'll get one good line, then an extra character that throws off your key, and everything else will be garbage after that.
