Classical Ciphers

Caesar Cipher

A substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet.

Vigenère Cipher

A method of encrypting alphabetic text by using a series of different Caesar ciphers based on the letters of a keyword.

Rail Fence Cipher

A transposition cipher that writes text in a zigzag pattern across multiple rows. The letters are then read off row by row to create the ciphertext.

Modern Ciphers

RSA Algorithm

Discover RSA, a robust asymmetric encryption algorithm widely used for secure data transmission. RSA relies on a pair of keys – public and private – to ensure data confidentiality and integrity.

Hash Functions

Hash functions are algorithms that transform an input of arbitrary size into a fixed-size string of characters, which is typically a digest that represents the data uniquely. Common hash functions include MD5, SHA-1, SHA-256, SHA-512, and RIPEMD-160, each providing varying levels of security and efficiency for data integrity and cryptographic applications.

Data Encryption Standard

A substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet.

Advanced Encryption Standard

A substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet.
