Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses. Symmetric algorithms convert plain-text ...

Additionally, this is the first instance where quantum computing attacks on multiple SPN structure symmetric cipher algorithms have achieved the performance of the traditional mathematical methods.

Symmetric ciphers Cryptography before the advent of computers relied on the use of ciphers. A cipher is a mapping from readable text to gibberish, and back again.

Symmetric encryption algorithms are commonly used for live traffic, with only handshake and the initial establishing of a connection done using (slower) asymmetric encryption as a secure channel ...

Encryption ciphers used in the SSL/TLS (Secure Sockets Layer/Transport Layer Security) negotiations can range from very strong to weak, and involve asymmetric ciphers, symmetric ciphers, key ...

The logical extreme would be to have a large menu of hashing algorithms, with widely scattered salt choices, and give a unique and long sequence of hashings to each user's password.

AES is a symmetric block cipher, operating on fixed-size blocks of data. The goal of AES was not only to select a new cipher algorithm but also to dramatically increase both the block and key size ...

In order to make information secret, you use a cipher - an algorithm that converts plain text into ciphertext, which is gibberish unless you have a key that lets you undo the cipher.
