基于这个密钥,我实现了rho攻击和CRT重构,从而获取到了秘钥(阶为自由平方值的复合值),成功获取到了秘钥,并成功定义了整套参数。我尝试用C语言把它们放到openssl中,然后把私钥和公钥都写在pem文件中。我有私钥:

我不明白我做错了什么。我得到了密钥参数,创建了私钥,确保它与给定的公钥相对应(这是真的)。但仍然使用命令
openssl dgst -sha256 -sign private_key_file -out sig_file text
openssl dgst -sha256 -verify public_key_file -signature sig_file text
输出“验证失败”!
