Explain key_length
WebA key is basically a binary number from 0 to n. The length of the key is 2 n. For example if you choose a 128 bit key, then you can say that your key will be any number between 0 to 2 128. In other words, your key length can be anything between 128 0s to 128 1s. Remember that higher the length of the key, the better your message is protected. 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. For this reason, asymmetric … See more The current standard for symmetric cryptography is the Advanced Encryption Standard (AES) algorithm. AES is a block cipher. The key sizes approved as secure for AES are 128, … See more Find below a table with the recommended key size for different algorithms. In certain cases, it is recommended to use AES with a key size equal to or greater than 192. Therefore, it is important to see the regulations related to … See more

WebOct 19, 2015 · The next two columns in the EXPLAIN output, ‘possible_keys’ and ‘key’ tells us about indexes which could be used for the particular query and the index chosen by the optimizer as the most efficient one. ‘key_len’ tells about the length of the index (or a prefix of an index) that was chosen to be used in the query. WebMar 3, 2024 · When I look at the EXPLAIN results, the key len value is always calculated based on the actual column length multiplied on the maximum number of bytes for the chosen encoding. Say, for a varchar(64) using utf8 encoding the key len is 192.
