问题 I use visual studio 2013 and windows 7 32bit. I want to verify digital signature by root and chain of certificate. So I get 0x80070057 error code in certcreatecertificatechainengine(). bool result = false; HCERTCHAINENGINE hChainEngine; CERT_CHAIN_ENGINE_CONFIG ChainConfig; PCCERT_CHAIN_CONTEXT pChainContext; //PCCERT_CHAIN_CONTEXT pDupContext; HCERTSTORE hCertStore; //PCCERT_CONTEXT pCertContext = NULL; CERT_ENHKEY_USAGE EnhkeyUsage; CERT_USAGE_MATCH CertUsage; CERT_CHAIN_PARA ChainPara;

问题 I need to create a server and client in c++ which exchange Diffie Hellman public key and encryption with AES_256 so far I am using MSDN sample for DH public key Generatinghttps://docs.microsoft.com/en-us/windows/win32/seccrypto/diffie-hellman-keys and its fine with RC4 in both side (client and server) but after Converting sample to AES_256 I get error 0x80090005(NET_BAD_DATA) on client-side EncryptDecrypt API.strange part is if both client and server runs on the same machine (not the same OS)

问题 I am trying to replace a openssl code to CNG winapi code. Below is the barebone openssl code which i have. const char *generator = ""; // 256 character hex string const char *prime = ""; // 256 character hex string dh = DH_new(); // Initialize dh's generator and prime BN_hex2bn(&(dh->g), generator); BN_hex2bn(&(dh->p), prime); // Generate public and private keys DH_generate_key(dh); // Extract server's public key from init_msg's 'key' BIGNUM *server_pub_key = BN_new(); BN_hex2bn(&server_pub

问题 I have a code that encrypts a file using AES CFB mode. While the code runs correctly in Windows 7, Windows 8 and previous versions of Windows 10, on Windows 10 Creators Update this line fails: if (!CryptAcquireContext(&hProv, NULL, MS_ENH_RSA_AES_PROV, PROV_RSA_AES, 0)) { std::cout << "CryptAcquireContext Error\n"; return 1; } What could be the reason for it? P.S I saw that it is deprecated on MSDN, but I thought that function was so common. 来源： https://stackoverflow.com/questions/48622293

问题 My problem is that I cannot get the AES 256 CTR output from the C code below to match the output from the OpenSSL command below. The C code produces this: 5f b7 18 d1 28 62 7f 50 35 ba e9 67 a7 17 ab 22 f9 e4 09 ce 23 26 7b 93 82 02 d3 87 eb 01 26 ac 96 2c 01 8c c8 af f3 de a4 18 7f 29 46 00 2e 00 The OpenSSL command line produces this: 5f b7 18 d1 28 62 7f 50 35 ba e9 67 a7 17 ab 22 3c 01 11 bd 39 14 74 76 31 57 a6 53 f9 00 09 b4 6f a9 49 bc 6d 00 77 24 2d ef b9 c4 Notice the first 16 bytes
