BOOL OW32::CCryptHash::Create (  HCRYPTPROV  hProv, ALG_ID  algId, HCRYPTKEY  hKey = NULL, DWORD  dwFlags = 0 )  [inline]

Create a new hash object. Returns: TRUE if successful, FALSE if not. Parameters: hProv  The cryptographic service provider to use. algId  The hashing algorithm hKey  For keyed hashes, the appropriate key dwFlags  Optional flags for CryptCreateHash

BOOL OW32::CCryptHash::GetAlgId (  ALG_ID *  pAlgId  )  [inline]

Get the algorithm id of the hash object. Returns: TRUE if successful, FALSE if not. Parameters: pAlgId  The output algorithm ID

BOOL OW32::CCryptHash::GetParam (  DWORD  dwParam, BYTE *  pbData, DWORD *  pdwDataLen, DWORD  dwFlags = 0 )  [inline]

Get a parameter from the hash object. Returns: TRUE if successful, FALSE if not. Parameters: pbData  The output parameter data dwDataLen  The length of the output parameter data buffer on input, the amount of data output on output. dwFlags  Optional flags for CryptHashData

BOOL OW32::CCryptHash::GetSize (  DWORD *  pdwSize  )  [inline]

Return the size of the hash. Returns: TRUE if successful, FALSE if not. Parameters: pdwSize  The output size.

BOOL OW32::CCryptHash::GetValue (  PBYTE  pbData, DWORD *  pdwDataLen )  [inline]

Get the hash value. Returns: TRUE if successful, FALSE if not. Parameters: pbData  The output hash data dwDataLen  The length of the output hash data buffer on input, the amount of data output on output.

BOOL OW32::CCryptHash::Hash (  const void *  pbData, DWORD  dwDataLen, DWORD  dwFlags = 0 )  [inline]

Hash a block of data. Returns: TRUE if successful, FALSE if not. Parameters: pbData  The data dwDataLen  The length of the data dwFlags  Optional flags for CryptHashData
