It's falling over with the linker error undefined reference to EVP_MD_CTX_free which implies that yes, it is correctly declared as a function in evp.h, but the linker can't find the implementation of EVP_MD_CTX_free, even though "C:/Program Files/OpenSSL-Win64/lib/libcrypto.lib" is...

EVP_MD_CTX_new()in 1.1.0 has replacedEVP_MD_CTX_create()in 1.0.x. EVP_MD_CTX_free()in 1.1.0 has replacedEVP_MD_CTX_destroy()in 1.0.x. You might try to use the older versions of these functions or make sure, that your linker really uses the >= 1.1.0 version of the op...
EVP_MD_CTX *EVP_MD_CTX_new(void); void EVP_MD_CTX_free(EVP_MD_CTX *ctx); 这两个函数用于创建和释放对称摘要上下文对象。 int EVP_DigestInit(EVP_MD_CTX *ctx, const EVP_MD *type); 初使化摘要上下文,type为摘要算法抽象集合。 成功返回1,失败返回0。 int EVP_DigestUpdate(EVP_MD_CTX *ctx...
EVP_MD_CTX_free(mdctx); // 输出哈希值 for (unsigned int i = 0; i < hash_len; i++) { printf("%02x", hash[i]); } printf("\n"); return 0; } 以上代码中,首先通过调用EVP_get_digestbyname函数获取了MD5摘要算法的指针。然后使用该指针初始化了一个EVP_MD_CTX结构体,并使用EVP_Digest...
In your special case the OpenSSL Crypto Lib is needed. And as you found out correctly the functions EVP_MD_CTX_new and EVP_MD_CTX_free were introduced in version 1.1. So I assume you have not installed the correct libraries. You can search for the term libcrypto....
