If you and your friends wish to share a secret you can write it in code and no one else will be able to read it. Codes are one way of writing in secret. Ciphers (密码) are another. In a code each word is written as a secret code word or code number. In a cipher each letter...
Cryptographic algorithms (or ciphers) play a large role in data security because they are used to generate cryptographic keys and digital signatures, protect payment transaction protection, secure web browsing, and message authentication.

cryptographic primitive - such as MD5, SHA-1, SHA-256, or even Blowfish or DES (which are block ciphers, yet they may be used to construct one-way hashes) - does not matter all that much.It's the higher-level password hashing method, employing salting and stretching, that makes a ...
A person who communicates through secret writing is called acryptographer. Cryptographers might use codes, ciphers or a combination of both to keep messages safe from others. What cryptographers create, cryptanalysts attempt to unravel. Throughout the history of cryptography, people who created codes...
Authenticate the server to the client and, optionally, authenticate the client to the server through certificates and public or private keys. Exchange random numbers and a pre-master secret. Together with some further data, these values will be used to create the shared secret key that the Recor...
AES is an iterative cipher based on a “substitution–permutation network.”It includes three block ciphers. AES-128 In AES-128 encryption, a key of 128-bit length is used to encrypt or decrypt a specific chain/block of messages. In this encryption, 128 bits of plain text are treated as...
