函数名:int EVP_PKEY_verify(EVP_PKEY_CTX *ctx, const unsigned char *sig, size_t siglen, const unsigned char *tbs, size_t tbslen); 功能描述:验签 说明: 1. 需一次性将待验签数据送完 2. 函数内做d2i_ECDSA_SIG将签名还原为SM2签名数据(r, s)。 参数说明: ctx (in/out) EVP_PKEY_CTX sig...
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...

Applications must now generate SM2 keys directly and must not create an EVP_PKEY_EC key first. It is no longer possible to import an SM2 key with domain parameters other than the SM2 elliptic curve ones. Validation of SM2 keys has been separated from the validation of regular EC keys, ...
