Explain key_length

In cryptography, key size, key length, or key space refer to the number of bits in a key used by a cryptographic algorithm (such as a cipher). Key length defines the upper-bound on an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), because the security of all algorithms can be violated by brute-force attacks. Ideally, the lower-bound on an algorithm's security is by design equal to t… WebDec 13, 2012 · For one AES is built for three key sizes 128, 192 or 256 bits. Currently, brute-forcing 128 bits is not even close to feasible. Hypothetically, if an AES Key had 129 bits, it would take twice as long to brute-force a 129 bit key than a 128 bit key. This means larger keys of 192 bits and 256 bits would take much much much longer to attack.

The EXPLAIN statement provides information about how MySQL executes statements. EXPLAIN works with SELECT , DELETE , INSERT , … The security of a cipher does not depend on the attacker not knowing the algorithm that was used for encryption. The security depends on how hard it is, mathematically, to break the code. There are two main types of attacks to a cipher: brute force and cryptanalysis. Let’s analyse the impact of the key size on a brute … See more The level of security of a cipher is considered a measure of the strength of a certain algorithm and is measured in bits. An algorithm that is 64-bits secure means that an attacker will … See more Asymmetric cryptography key strength is based on the complexity of integer factorization. This problem is hard to solve (it needs a lot of time) but it takes less time than a brute force attack.
