Returns the MD5 hash of this certificate's public key. For all user-defined property identifiers, pvData points to an array of BYTE values. For more information about each property identifier, see the documentation on the dwPropId parameter in. PvData out A pointer to a buffer to receive the data as determined by dwPropId. Structures pointed to by members of a structure returned are also returned following the base structure. Therefore, the size contained in pcbData often exceeds the size of the base structure. This parameter can be NULL to set the size of the information for memory allocation purposes.
For more information, see. PcbData in, out A pointer to a DWORD value that specifies the size, in bytes, of the buffer pointed to by the pvData parameter. When the function returns, the DWORD value contains the number of bytes to be stored in the buffer.
To obtain the required size of a buffer at run time, pass NULL for the pvData parameter, and set the value pointed to by this parameter to zero. If the pvData parameter is not NULL and the size specified in pcbData is less than the number of bytes required to contain the data, the function fails, returns ERRORMOREDATA, and the required size is placed in the variable pointed to by the pcbData parameter. Return value If the function succeeds, the function returns TRUE. If the function fails, it returns FALSE. For extended error information, call. Some possible error codes follow.
Return code Description CRYPTENOTFOUND The certificate does not have the specified property. ERRORMOREDATA If the buffer specified by the pvData parameter is not large enough to hold the returned data, the function sets the ERRORMOREDATA code and stores the required buffer size, in bytes, in the variable pointed to by pcbData. Errors from the called function can be propagated to this function. Remarks Properties are not stored inside a certificate. Typically, they are associated with a certificate after the certificate response is received and then saved with the certificate in the store. For security reasons, we recommend that you validate property values before saving them and that you save only informational properties such as the CERTFRIENDLYNAMEPROPID value in user stores.
All other property types should be saved in local computer stores. Your code can use a macro to evaluate the class of hash for a certificate context. For more information, see. Examples For examples that use this function, see and.

How to get Serial number of certificate in hex format string using cryptoapi? I have try using LPTSTR pszSerial = NULL; DWORD cbSerial = 0; CryptBinaryToString(pCertContext-pCertInfo-SerialNumber.pbData,pCertContext-pCertInfo-SerialNumber.cbData,CRYPTSTRINGHEX,NULL,&cbSerial); pszSerial = new TCHARcbSerial; CryptBinaryToString(pCertContext-pCertInfo-SerialNumber.pbData,pCertContext-pCertInfo-SerialNumber.cbData,CRYPTSTRINGHEX,pszSerial,&cbSerial); But the result not what i want, i can get serial number but it reversed.
