A cipher suite specifies one algorithm for each of the following tasks: Key exchange Bulk encryption Message authentication In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with "code", as they are both a set of steps that encrypt a messa…

WebThe pigpen cipher uses graphical symbols assigned according to a key similar to the above diagram. [1] The pigpen cipher (alternatively referred to as the masonic cipher, Freemason's cipher, Napoleon cipher, and tic-tac-toe cipher) [2] [3] is a geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid.

WebCiphertext is encrypted text transformed from plaintext using an encryption algorithm. Ciphertext can't be read until it has been converted into plaintext (decrypted) with a key. The decryption cipher is an algorithm that transforms the ciphertext back into plaintext. The term cipher is sometimes used as a synonym for ciphertext. WebCipher suites defined for TLS 1.2 cannot be used in TLS 1.3, and vice versa, unless otherwise stated in their definition.
