WebJul 4, 2001 · Cryptology is divided into – 1) Cryptography and 2) Cryptanalysis. Cryptography deals with the creation of ciphers and cryptosystems. Cryptanalysis deals with the breaking of ciphers and cryptosystems. Cryptanalysis can be done by various approaches or attacks like brute force, chosen plaintext and man in the middle attack. WebSep 26, 2024 · The first step in breaking cryptography is identifying the cryptographic algorithm in use.

WebNov 11, 2024 · Caesar cipher is one example of symmetric key cryptography, and it’s one of the oldest and easiest ways to implement cryptography. Caesar cipher is a substitution cipher in which alphabets shift their order by a fixed number of positions. Encrypting and decrypting Caesar cipher is easy, as the method is fixed and no key is required.

A variant of the Vigenère cipher, which uses numbers instead of letters to describe the sequence of shifts, is called a Gronsfeld cipher. Gronsfeld ciphers can be solved as well through the Vigenère tool.

WebRC4 was designed by Ron Rivest of RSA Security in 1987.
