Generates a hash over the contents of the specified file.

Syntax

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

Parameters

szFilePath
[in] The name of the file to hash.

piHashAlg
[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.

pbHash
[out] A byte array containing the generated hash.

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

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

Return Value

S_OK if the method completed successfully; otherwise, an HRESULT value that indicates failure (see Common HRESULT Values for a list).

Remarks

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