CryptHashCertificate2 function (wincrypt.h)
The CryptHashCertificate2 function hashes a block of data by using a CNG hash provider.
BOOL CryptHashCertificate2( [in] LPCWSTR pwszCNGHashAlgid, [in] DWORD dwFlags, void *pvReserved, [in] const BYTE *pbEncoded, [in] DWORD cbEncoded, [out] BYTE *pbComputedHash, [in, out] DWORD *pcbComputedHash );
The address of a null-terminated Unicode string that contains the CNG hash algorithm identifier of the hash algorithm to use to hash the certificate. This can be one of the CNG Algorithm Identifiers that represents a hash algorithm or any other registered hash algorithm identifier.
A set of flags that modify the behavior of this function. No flags are defined for this function.
Reserved for future use and must be NULL.
The address of an array of bytes to be hashed. The cbEncoded parameter contains the size of this array.
The number of elements in the pbEncoded array.
The address of a buffer that receives the computed hash. The variable pointed to by the pcbComputedHash parameter contains the size of this buffer.
[in, out] pcbComputedHash
The address of a DWORD variable that, on entry, contains the size, in bytes, of the pbComputedHash buffer. After this function returns, this variable contains the number of bytes copied to the pbComputedHash buffer.
If the function succeeds, the function returns nonzero (TRUE).
If the function fails, it returns zero (FALSE). For extended error information, call GetLastError. Some of the possible error codes are identified in the following topics.
