As for #8435, my viewpoint is that we should be unable to generate a signature with such invalid key, namely, you will always get a nullptr when sm2_do_sign with d == (N -1). And the issue here is quite different. It can reach the result and return a (r,s). Exactly, I don...
在SM2算法中,我们可以使用私钥对信息进行签名,然后使用公钥进行验签。以下是一个使用SM2算法进行签名验签的示例代码: AI检测代码解析 importcom.sun.net.ssl.internal.ssl.Provider;importorg.bouncycastle.jce.provider.BouncyCastleProvider;importjava.security.*;importjava.util.Base64;publicclassSM2SignVerify{publicstat...
