Overview. In this tutorial, we present the Elgamal cryptographic algorithm. It uses asymmetric cryptography to encrypt messages. 2. Symmetric Cryptography. In symmetric cryptography, we use a secret key to apply an encryption algorithm to a message . Consequently, the algorithm’s output is cipher text .
WebCryptography 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. Today’s algorithms and cryptosystems are much more advanced. WebApr 30, 2014 · Cryptography is the science of information security. The word is derived from the Greekkryptos, meaning hidden. Cryptography is closely related to the disciplines of cryptology andcryptanalysis. Cryptography includes techniques such as microdots, merging words with images, and other ways to hide information in storage or transit.
