comment Physical entropy source: How many bits entropy per byte is sufficent?
@curiosity: That's correct! As I linked above, there is a case where a malicious, privileged data source can actually decrease the security of a RNG when mixed into it, but this is essentially an edge case.

comment Physical entropy source: How many bits entropy per byte is sufficent?
@curiosity: For example, I just ran ent on a JPEG photo of me at a party. Result was Entropy = 7.970617 bits per byte but I can assure you that the picture is a far from being near truly random.

comment Physical entropy source: How many bits entropy per byte is sufficent?
@curiosity: Passing ent is a necessary but not sufficient condition for a random stream. If your stream fails ent, it (with overwhelming probability) isn't truly random. If your stream passes ent, it may or may not be truly random - but ent cannot determine which. It is a tool that is only useful as a negative indicator.

comment Can i get a list of over hard and long RSA keys? i think i have found a vulnerability in RSA Algorithm
Ah, yeah, RSA-2048 would have been a better choice in retrospect. Truth be told, I just completely forgot about it.

I think this question uniquely qualifies for the "too broad" close reason: there are (literally) an infinite number of possible answers.

@user3651521: Yes. That is $n=pq$ where $p,q$ are distinct primes roughly 1024 bits in size.
