🔍 Features

🔁 Substitution Ciphers

• Caesar Cipher: Shifts letters by a fixed number of positions.
• Vigenère Cipher: Uses a keyword to determine different Caesar shifts per letter.
• Hill Cipher: Uses matrix multiplication for encrypting letter pairs or triplets.

🔄 Transposition Cipher

• Rail Fence Cipher: Zigzag writing pattern read row-wise.

🔐 Modern Algorithms

• DES (Data Encryption Standard): Symmetric-key block cipher using a 56-bit key.
• RSA Algorithm: Public-key cryptosystem for secure transmission.
• Diffie-Hellman Key Exchange: Secure key exchange method over a public channel.
• SHA-1 (Secure Hash Algorithm): Hash function producing a 160-bit hash.
