comment Multi-key decryption
OK, tried to rewrite it a bit, could you take a look at the last paragraph? It doesn't parse for me.

comment Implementation Attacks on Hashes
@RichieFrame Sounds like an answer more than a critique on the question. Or do we consider lists as off topic? (Have to defend my fellow owl :) )

@ddddavidee Those comments would make a fine answer when put together and if the contents of the links are briefly explained.

comment Rely on NSA Suite B Cryptography?
There are efforts like safecurves.cr.yp.to , that try and solve this scientifically. Basically they are saying that the curves could have been better, and that the missing reasoning on how the input parameters have been chosen leaves room for doubt. No yes/no answer, as I've already indicated. Either somebody proves that no attacks are present, or somebody shows that there are (both are very hard - and maybe impossible - to accomplish). Before that no final yes/no answer can be composed.

Sorry, that may not be the answer you were hoping for, but you cannot simplify every question until you can just answer with "yes" or "no".

Should perfect sharing secrecy be perfect forward secrecy, or are the terms synonymous?

@RickyDemer Yeah, I think I tried to be a bit too clever there, rewrote anonymity part.

@RickyDemer Would that be true even if the public keys are not known to attackers? I guess for RSA, with enough information the modulus could be distinguished?

comment Streaming mode of operation that is more resistant against nonce reuse
@Thor SIV actually comes a long way. It seems size efficient, but not very efficient with regards to CPU time. Thanks!
