comment Help with RSA-2048 crypto ransom virus
I'm voting to close this question as off-topic because it's about recovering from malware, not about cryptography.

comment Checking the integrity of RSA public key
How about the attacker sending chosen ciphertexts or plaintexts with varying values of $e$ (assuming a scenario where the attacker can force the cryptographic module to reload $e$ from the breached storage at will)? Could that reveal information that fixed-$e$ attacks wouldn't?

comment Probability of guessing random 128-bit AES key
I'm voting to close this question as off-topic because it is about counting, with only a superficial application to cryptography.

comment How does generating random numbers “remove entropy from your system”?
“once you've used a seed you should really throw it out and collect another one”: that's grossly misleading. Once you've used a seed, you throw it out, but you can keep using the PRNG seeded from that seed for a very long time.

comment Keyless integrity checking with SHA-256
Why don't you store the size as well as the hash? It's usually useful for other reasons (allocating sizes, detecting obvious transmission errors, etc.).

comment gpg --gen-random quality level: is higher “better”?
/dev/random does not really have higher guarantees than /dev/urandom (it's only better in one specific case, which is a newly-installed machine).
