ICLRStrongName::GetHashFromFileW Method

Article
09/15/2021

Generates a hash over the contents of the file specified by a Unicode string.

Syntax

HRESULT GetHashFromFileW (
    [in]  LPCWSTR   wszFilePath,  
    [in, out] unsigned int   *piHashAlg,  
    [out] BYTE      *pbHash,  
    [in]  DWORD     cchHash,  
    [out] DWORD     *pchHash  
);

Parameters

wszFilePath
[in] The Unicode 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 pointed to by pbHash.

pchHash
[out] The size, in bytes, of 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::GetHashFromFile method, except that the file name specification is Unicode instead of ANSI.
