Cryptography Algorithms

This repository contains Pure Python3 implementations of various cryptographic algorithms. Feel free to explore and use them in your projects.

Algorithms Included

1. DES (Data Encryption Standard)

   • A symmetric-key block cipher used for data encryption.
   • Implementation: des.py

2. AES (Advanced Encryption Standard)

   • A widely used symmetric-key encryption algorithm.
   • Implementation: aes.py

3. RSA (Rivest–Shamir–Adleman)

   • An asymmetric encryption algorithm for secure communication.
   • Implementation: rsa.py

4. MD5 (Message Digest Algorithm 5)

   • A widely used hash function for generating fixed-size hash values.
   • Implementation: md5.py

5. MITM_DH (Man-in-the-Middle Diffie-Hellman)

   • A demonstration of the Diffie-Hellman key exchange vulnerable to a man-in-the-middle attack.
   • Implementation: mitm_dh.py

6. SHA-512 (Secure Hash Algorithm 512)

   • A cryptographic hash function producing a 512-bit hash value.
   • Implementation: sha512.py

7. DSS (Digital Signature Standard)

   • A standard for digital signatures based on the use of public-key cryptography.
   • Implementation: dss.py
