CTF RSA 工具

  • RSA大数分解网站http://www.factordb.com/index.php

  • 大数分解平台https://cloud.sagemath.com/

    factor(0x123)
    factor(123)
    
  • RSA tool2

  • yafu 如果两个素数相差很近,可采用费马分解

    factor(0x123)
    factor(123)
    
  • rsatool.py 标准工具 用于已有p,q生成私钥

    ./rsatool.py -p num1 -q num2 -o priv.key
    
  • RsaCtfTool.py 提供公钥可输出n,e

  • openssl

    输出公钥信息
    openssl rsa -noout -text -inform PEM -in public.key -pubin
    
    openssl rsautl -decrypt -in level1bin.passwd.enc -inkey ../priv.key -out level1.passwd -oaep
