WebAn example This example uses the common unix utility "md5sum", which hashes the data on stdin to a 128 bit hash, displayed as 32 hex digits. Assume the password is "mysecretpass" and both the client and the server know this.The client connects to the server. The server makes up some random data, say "sldkfjdslfkjweifj ”.The server sends this data to client. WebHistory of Cryptography Cryptography began with ciphers, the first of which was the Caesar Cipher. Ciphers were a lot easier to unravel compared to modern cryptographic algorithms, but they both used keys and plaintext. Though simple, ciphers from the past were the earliest forms of encryption.
