Comment(by reganeet):

 > The constructor has a validate flag in case they want to accept
 malformed data so also calling this function 'validate' would be
 confusing.
 Right, I didn't think of that.

 > However, maybe we should come up with a more descriptive name than
 is_valid()? Would is_signature_valid() be better?
 Well, I prefer is_valid() for its conciseness. :)

 > Yup, please add all of the details you think would be helpful for future
 people trying to figure this out to this ticket.
 Nick's conversation with me contains some useful details:
 https://lists.torproject.org/pipermail/tor-dev/2012-May/003544.html
 The key is to find a crypto library that implements the pkcs1 signature
 verification process (part 3). IMHO, pyCrypto and M2Crypto don't have it,
 and python-rsa verify() function only works with the signature created by
 its sign() function.

 > Also, lets add that task to the dev wiki...
 Done.
