ID: 1853
标题: UniveRSAlity
描述: Author : Neobeo Description I've been learning about RSA, but choosing random primes seems quite arbitrary. Using universal "nothing-up-my-sleeve" constants like pi and e should make it more secure, so that you can't get my flag. Difficulty Medium
类型: Crypto

UniveRSAlity的解题过程涉及通过遍历找到满足p-1和q-1光滑的素数p和q,生成符合要求的m值并验证其立方根特性。具体步骤包括限制p和q的高位、生成随机明文m并调整使其立方根为整数,最终通过多次交互计算gcd获取n值。详细过程可参考博客中的代码示例和数学推导。
