comment Cannot verify rsa signature on Android
I'm voting to close this question as off-topic because it is a programming question about Java APIs. It can be asked on Stack Overflow, with complete code and input to reproduce the problem.

comment How to securely store data? / How to securely encrypt a file?
Given the scope, I suggest a chat or meta discussion on the topic first. There's a lot of good material in your answer, but I fear that it's all packed so tightly that it's difficult to find the relevant parts for any given problem.

comment How to securely store data? / How to securely encrypt a file?
I am voting to close as too broad because, seeing the answer, it's clear that there's just too much stuff to say on the topic. Besides, the answer to the question as written is “use an existing implementation such as dmcrypt, TrueCrypt, GPG, etc.”.

comment Is Information Loss in Crystalline Cipher a Good Approach to Anti-Cryptanalysis?
Your question is still too broad. Each of these points could make one question, if you explained a bit better what you're after. Have you read peer-reviewed articles about this cipher? Documentation from the original author isn't enough to consider a cipher worth pursuing.

I'm voting to close this question as off-topic because it is about risk management, not about cryptography. It was on-topic on Information Security.
