1. Open the SecurityPackage.sln file.
2. Download the recommended .NET Framework for the template.
3. Write your implementation for your algorithm.
4. Go to the Test tab and choose Test Explorer.
5. Right-click on the required algorithm and then choose Run to execute all test cases on the chosen one.

Milestones

Milestone 1: Implementation of Encryption, Decryption, and Analysis Functions

The primary goal of this milestone is to implement encryption, decryption, and analysis functions for various cryptographic algorithms. The following algorithms are required to be implemented:

• Ceasar Cipher
• Autokey Vigenère Cipher
• Repeating Key Vigenère Cipher
• Rail Fence Cipher
• Columnar Transposition Cipher
• Monoalphabetic Cipher
• Hill Cipher
• Playfair Cipher

NOTE: The implementation of the Playfair Cipher Analysis is marked as "OPTIONAL" and comes with BONUS points, making it non-mandatory.

Milestone 2: Implementation of Extended Euclidean, DES, and AES

This milestone focuses on implementing additional encryption and decryption algorithms, including:

• Extended Euclidean
• Data Encryption Standard (DES)
• Advanced Encryption Standard (AES)

These algorithms add to the complexity and security of the encryption methods implemented in Milestone 1.

Milestone 3: Implementation of RSA, Diffie-Hellman, RC4, ElGamal CryptoSystem "OPTIONAL" and MD5 "Possibly BONUS Not Sure"

In this milestone, the focus shifts to implementing more advanced encryption and cryptographic algorithms, including:

• RSA (Rivest-Shamir-Adleman)
• Diffie-Hellman key exchange
• RC4 (Rivest Cipher 4)
• ElGamal Cryptosystem

The implementation of these algorithms further enhances the security and versatility of the encryption techniques employed in the project. Additionally, the implementation of MD5 hashing may be considered for bonus points, providing an extra layer of data integrity verification.
