WebApr 17, 2015 · The most natural definition of encryption key space is the set of pairs ( N, e) matching the applicable conditions defined in a particular variant of RSA. The cardinality of the encryption key space is the number of elements in that set if it is finite, else the cardinality is ℵ 0 (the cardinality of N and all countable sets ). WebA key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on the security of the key …
