确认evp_cipher_ctx_init 函数的来源和用途: evp_cipher_ctx_init 是OpenSSL 库中用于初始化 EVP 密码上下文的一个函数。EVP(高级加密标准)接口是 OpenSSL 提供的一个高级加密接口,用于简化加密操作。检查代码中是否正确包含了相应的头文件或库文件:
HMAC_CTX_init(&hctx); HMAC_Init_ex(&hctx, mac_key, sizeof(mac_key), EVP_sha1(), NULL); HMAC_Update(&hctx, pTemp + offset, DEFAULT_PAGESIZE - reserve - offset + IV_SIZE); HMAC_Update(&hctx, (const unsigned char)& nPage, sizeof(nPage)); HMAC_Final(&hctx, hash_mac, &...

HMAC_CTX_new() returns a pointer to a new HMAC_CTX on success or NULL if an error occurred. HMAC_CTX_reset(), HMAC_Init_ex(), HMAC_Update(), HMAC_Final() and HMAC_CTX_copy() return 1 for success or 0 if an error occurred. HMAC_CTX_get_md() return the EVP_MD previously ...
That’s whereINIT_ONCE_CTX_RESERVED_BITScomes in. TheINIT_ONCE_CTX_RESERVED_BITSvalue is the number of bits that the one-time initialization code uses after initialization is complete; the other bits are free for you to use yourself. The value ofINIT_ONCE_CTX_RESERVED_BITSis 2, which mean...
