comment What does “circuits” mean in Cryptography?
@ThomasM.DuBuisson that (conditionals become bit masking where each branch is evaluated) is something that I think a lot of people miss. Thanks for pointing that out.

comment Is it possible to add OpenSSL engine for a block algorithm with different input and output block size?
I would think the openssl mailing list to be a much better place to ask this. Don't get me wrong. I am glad you are using our site and hope you continue to, but I just want you to get the best answer possible.

comment Is a die implemented in a physics engine truly random?
@Beska, given that view, is there any such thing as truly random?

comment What are SNARKs?
Copying and pasting a link is not an answer. The answer may be contained in the link, but link-only answers are of very poor quality. Perhaps you can expand?

comment In RSA, why does Alice's $N$ need to be relatively prime to Bob's $N$?
Theoretically, if good random number generators are used, there are enough primes to ensure this won't happen. In practice, however, it has been the case that this has happened (see this).

comment Understanding Cryptography practically
Read this site and Security.SE often. You'll learn a ton. That said, this sort of a question is off-topic here as it is more of a discussion. Our chat room is not very active. You could ask on there and may get some info. The chat room on Security.SE is much more active and you should get some good info there.

Should depend on where the physics engine gets the randomness it uses internally.

comment Can DH_anon really be exploited by an attacker?
Could you give more context? I think what you are saying is that you typically see it recommended that DH_anon be disabled (similarly ECDH_anon) on a server since it is susceptible to MitM, but you have never seen a client that supports DH_anon (or ECDH_anon), so you are thinking it isn't really a threat in the real world. Is that accurate?
