Thanks! I don't know much about crypto, so all I can do is try it out.
It seems that the public exponent comes first in the encoded version,
so I switched those two read_hint() lines, and then it appears to work
- the key can successfully verify signatures created with the
corresponding private key. This looks a lot better than "rip these
bytes off, shove those bytes on, and see how it goes".
