WebThe security of the encryption usually depends on the key length. In this article, I’ll show why key length is a very important topic in cryptography. Key length (a.k.a. key size) is the number of bits of a key used to encrypt a message. The length on its own is not a measure of how secure the ciphertext is.

WebIn cryptography, the RSA problem summarizes the task of performing an RSA private-key operation given only the public key.The RSA algorithm raises a message to an exponent, modulo a composite number N whose factors are not known. Thus, the task can be neatly described as finding the e th roots of an arbitrary number, modulo N. For large RSA key … 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 ).
