WebBased on public key cryptography, the D-H algorithm is a method for securely exchanging a shared key between two parties over an untrusted network. It is an asymmetric cipher used by several protocols including SSL, SSH, and IPSec. It allows two communicating parties to agree upon a shared secret, which can then be used to secure a ...

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 ... In cryptography, a key is a string of characters used within an encryptionalgorithm for altering data so that it appears random. Like a physical key, it locks (encrypts) data so that only someone with the right key can unlock (decrypt) it. The original data is known as the plaintext, and the data after the key encrypts it is … See more Before the advent of computers, ciphertext was often created by simply replacing one letter with another letter in the plaintext, a method known as a "substitution cipher." For instance, suppose … See more Although the above examples of early cryptography illustrate how using a random string of information to turn plaintext into ciphertext works, cryptographic keys today are far more complex.
