题目给了e、p、q，还给了c 思路：根据两个质数p、q可以算出n和φ(n)，从而算出解密参数d（d为e在模φ(n)下的逆元），由密文c、解密参数d、还有素数乘积n可以算出明文m。 解密代码 得到明文：flag{b4by_R5A} See more 题目给了e、n，还有密文c 思路：我们缺少参数p、q，也就缺少φ(n)，但是我们发现n这个数比较小，很有可能在可接受时间内被现有计算机分解质因数出两个素数p、q 我们使用yafu工具分 … See more 题目给了我们e、n、c，发现e=3，是一个很小的值。 RSA的加密公式为 c = m e m o d n 可 变 形 为 c + k ∗ n = m e c = m^e \quad mod \quad n\\ 可变形为\quad c + k * n = m^e c=memodn可变形为c+k∗n=me 如果c和n比较大，而e … See more 题目给了我们2组e、n、c，而且n是比较大的，如果不是特殊的n不太好分解~~，但是经观察发现这两组参数中的e参数是一样的（貌似没啥用）。~~ … See more 题目给了我们2组e、n，还有对应的c，经过观察发现这两组参数的n是一样的。如果将相同的明文分别用两组公钥(e1, n1)、(e2, n2)进行加密，那么攻击者只需要将这两组公钥都拿到手， … See more WebMay 26, 2024 · babyrsa. 先看txt 直接上脚本： import gmpy2 import binascii e = 65537 p = q = c = phi = (p-1) * (q-1) d = gmpy2. invert (e, phi) m = gmpy2. powmod (c, d, p * q) print (binascii. unhexlify (hex (m) [2:])) easyrsa1. 先看txt： 先利用factordb分解n 得到 最后利用 … Web没错这是一道CTF题 （ctfshow 2024 11/11 菜狗杯）#第一个作品 #生活碎片 #初来乍到请多关照 - 探姬于20241111发布在抖音，已经收获了63个喜欢，来抖音，记录美好生活！ easehold化妆镜怎么样
