Cryptography labs

There are the results of my lab works on cryptographic protocols and standards in the summer of 2017.

I realized the following algorithms:

1. One-Time Pad
2. DES
3. AES
4. RC4
5. RSA
6. Hash-Table
7. SHA256
8. Entropy calculation
9. Meet-In-The-Middle attack on 2DES
10. Diffie-Hellman key exhange

I used C++ with static library Crypto++ (cryptography algorithms) and MPIR (work with long numbers) for this.
