It seems we have had a few questions recently asking for references on implementations. For example:

Are these sorts of questions off-topic here? Should we update the FAQ to address this? Is there another SE site these should be migrated to?

Update 1
Here is another example: Any practical implementation of homomorphic hashing?

Update 2
Here is yet another example: Ciphertext-Policy Attribute-Based Encryption Java Implementation


My leaning would be to close the questions as off-topic just like we close list questions. As to another SE site, I am not sure.


They seem on-topic to me (if they meet all our other criteria, like asking an answerable question, with well-defined criteria for evaluation of the answer, and they "show their work"). I don't see a problem with these questions. I suggest we treat them as on-topic.

They are answerable if an implementation exists. Otherwise it is hard for anyone to say "no, no implementation exists". Also, if I say yes implementation X exists and you say implementation Y exists, how do you evaluate the two answers? – mikeazo Feb 27 '13 at 15:53
And the FAQ clearly states implementation questions "probably" belong on Security, so perhaps the FAQ should be addressed. – Thomas Feb 27 '13 at 16:02
@Thomas, FWIW I asked on Security's meta. – mikeazo Feb 27 '13 at 19:09
