The key held by the cryptographic service provider (CSP) and referenced by the hKey parameter specifies the algorithm used to encrypt the data parameter. Syntax 複製 BOOL CRYPTFUNC CryptEncrypt( HCRYPTKEY hKey, HCRYPTHASH hHash, BOOL Final, DWORD dwFlags, BYTE* pbData, DWORD* pdwDataLen, ...
如果为pbData分配的缓冲区不够大,则GetLastError返回ERROR_MORE_DATA,并将所需的缓冲区大小(以字节为单位)存储在由pdwDataLen指向的DWORD值中。 如果pbDataNULL,则不返回错误,并且函数将加密数据的大小(以字节为单位)存储在由pdwDataLen指向的DWORD值中。 这样,应用程序就可以确定正确的缓冲区大小。
NCryptEncrypt函数加密数据块。 语法 C++ SECURITY_STATUSNCryptEncrypt( [in] NCRYPT_KEY_HANDLE hKey, [in] PBYTE pbInput, [in] DWORD cbInput, [in, optional] VOID *pPaddingInfo, [out] PBYTE pbOutput, [in] DWORD cbOutput, [out] DWORD *pcbResult, [in] DWORD dwFlags ); ...
CryptEncryptMessage 是完成 加密消息中列出的所有任务所需的唯一函数调用。 需要初始化数据结构。 下图显示了指向结构或数组及其初始化数据的这些函数参数之间的关系。 此示例还使用 CryptDecryptMessage解密消息。加密数据获取指向要加密的内容的指针。 确定要加密的内容的大小。 获取加密提供程序的句柄。 打开证书存储。
It was a straightforward translation of the MSDN sample. I suspect the problem you're having with ERROR_MORE_DATA is that the encryption can create more data than you're encrypting, so you need to have a buffer that's larger than the data block, plus some if i...
