接下来,你可以使用OpenSSL提供的API来实现HmacSHA1签名功能。以下是一个简单的示例代码: #include <openssl/hmac.h> void hmac_sha1(const unsigned char *text, int text_len, const unsigned char *key, int key_len, unsigned char *digest) { HMAC_CTX *ctx = HMAC_CTX_new(); HMAC_Init_ex(ctx, ...
ctx = HMAC_CTX_new(); HMAC_Init_ex(ctx, key, keyLen, md, NULL); HMAC_Update(ctx, msg, msgLen); HMAC_Final(ctx, md_value, &md_len); HMAC_CTX_free(ctx); 而低版本的openssl(例如1.0.2)是可以直接在栈上声明 struct 对象。 HMAC_CTX ctx; ...
EVP_CIPHER_CTX *EVP_CIPHER_CTX_new(void); 1. 创建新加密上下文EVP_CIPHER_CTX对象, 并将其作为返回值返回 void EVP_CIPHER_CTX_free(EVP_CIPHER_CTX *ctx); 1. 清除并释放加密上下文对象(防止数据泄露),参数为需要释放的EVP_CIPHER_CTX对象,在所有加密操作结束后调用该函数 ...
HMAC_CTX *HMAC_CTX_new(void);创建HMAC上下文结构。void HMAC_CTX_free(HMAC_CTX *ctx);释放HMAC上下文结构。int HMAC_Init(HMAC_CTX *ctx, const void *key, int len, const EVP_MD *md);初使化HMAC上下文结构，key和len指定密码。成功返回1，失败返回0。int HMAC_Update(HMAC_CTX *ctx, ...
