GetHashFromFile Function

Generates a hash over the contents of the specified file.

This function has been deprecated in the .NET Framework version 4. Use the ICLRStrongName::GetHashFromFile method instead.

HRESULT GetHashFromFile (
    [in]  LPCSTR   szFilePath,
    [in, out] unsigned int   *piHashAlg, 
    [out] BYTE     *pbHash,    
    [in]  DWORD    cchHash,    
    [out] DWORD    *pchHash


[in] The name of the file to hash.


[in, out] The algorithm to use when generating the hash. Valid algorithms are those defined by the Win32 CryptoAPI. If piHashAlg is set to 0, the default algorithm CALG_SHA-1 is used.


[out] A byte array containing the generated hash.


[in] The maximum size of the buffer that pbHash points to.


[out] The size, in bytes, of the returned pbHash.

This function is the same as GetHashFromFileW, except that the file name specification is ANSI instead of Unicode.
