WebSecurity level. In cryptography, security level is a measure of the strength that a cryptographic primitive — such as a cipher or hash function — achieves. Security level is usually expressed as a number of " bits of security" (also security strength ), [1] where n -bit security means that the attacker would have to perform 2 n operations ...
