comment How was 256-bit WEP cracked as well?
@nightcracker: Could you explain it with the probability distributions mentioned by the authors: 'Andreas Klein showed that there is a correlation in RC4 between Keybytes 1 to i-1, the keystream and the keybyte i. If the keybytes 1 to i-1 and the keystream are known, it is possible to guess the next unknown keybyte with a probability of about 1.36/256'

Wikipedia states that 'leaving 232 bits for actual protection'. So, you are saying that you don't need to crack the 232 bits? Then how many (bits) of the 232 bits do you need to crack?

No, I am not using WEP. Just trying to understand why 256-bit encryption is not strong enough. While 256-bit keys are considered secure, when talking about AES for example. What are the names of this attack?

comment AES: keylength and password length?
How about skipping the key derivation function, if the password length and keylength match?

comment Are there Cryptography certifications variants of CISSP?
CISSP does not really cover the mathematical part of crypto.

comment If we can find prime numbers larger than 17 milion digits, why can't we find all 1024bit primes?
*subatomic particle... It turns out that roughly 68% of the Universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the Universe. '

How about subatomic particles from CERN? And dark matter?' It turns out that roughly 68% of the Universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the Universe. '

'RSA moduli are pseudoprimes, not primes.' <-- so??? You still need to compute 2 2^1024 primes?
