Takeaways from solving CryptoHack by Arseniy Reutov Medium

WebAug 31, 2024 · Show that the only solution of the congruence equation a x ≡ b ( mod p) is x ≡ a − 1 b ≡ a p − 2 b ( mod p) (2 answers) Closed 2 years ago. I was solving a problem Called Modular inverting on Crypto Hack the problem states that: if we have 3 * d ≡ 1 mod 13 how can we get d using Fermat Little Theorem WebJul 30, 2024 · 基本概念理解: 1. P, Q, R在一条线上【R (x,y)】⇒ R' (x,-y) = P+Q 2. P+Q+Q = 0 ⇒ P+2Q = 0 ⇒ P' = 2Q or P+Q = Q' 3. P+Q+0 = 0 ⇒ P+Q = 0 4. P+P+0 = 0 ⇒ 2P+0 = 0 ⇒ 2P = 0 EC中的加法公式: 当P≠Q: 当P=Q： EC乘法公式: 我们可以通过n次加法的形式解释n*P的乘法, 例如2*3 = 3+3 或者 3*2 = 2+2+2 但是这里有个弊端就是n值越大，这样算法的复杂度越高 … WebOct 29, 2024 · CryptoHack: Modular Arithmetic Writeups for CryptoHack’s Modular Arithmetic Course October 29, 2024 · 18 min Table of Contents Greatest Common Divisor Solution Extended GCD Solution Modular Arithmetic 1 Solution Modular Arithmetic 2 Solution Modular Inverting Solution Quadratic Residues Solution Legendre Symbol … chinese delivery 78749
