| | | | | Last weekend TetCTF held their new year CTF competition. I felt particularly nostalgic playing this, as it was the TetCTF 2020 CTF where Hyper and I played the crypto challenges and soon after decided to make CryptoHack together. Something about Ndh's crypto challenges really make me want to keep learning. | |

| | | | | Motivation RSA (Rivest-Shamir-Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and is different from the decryption key which is kept secret. If I wanted to comprehend zero knowledge proofs, then understanding the grand-daddy of public-key cryptosystems is a must. Background Maths Exponential Rules 1 $$ \begin{align} \label{eq:exponent_rule} g^{a-b} &= \dfrac{g^a}{g^b} \newline g^{a+b} &= g^a g^b \n... | |

| | | Motivation In my quest to understand zero knowledge proofs from the ground up, I've decided to go back to the basics, and really understand how everyday cryptography tools work, not just how to use them. In this post, I'll attempt to explain how and why the diffie hellman key exchange protocol works, along with proofs and a working example. The examples are purely for educational purposes only! Introduction The Diffie-Hellman key exchange protocol is an algorithm that allows two parties to generate a uni... | ||
