QHASH_StringDigest

int QHASH_StringDigest( [ in ]int nAlgID, [ out ]QHASH_Digest *pDigest, [ in , string ] unsigned char* pSrc );

Return value

Zero if calculation is successful, otherwise nonzero.

Note. All possible return values are specified in the Error Codes List.

Parameters

nAlgID

    [in] The ID of the hash/checksum algorithm selected for calculations. For example, nAlgID has to be set to SHA1_ALGID when you need to calculate the digest using SHA-1 hash algorithm.

    Note. All supported hash/checksum algorithms with their corresponding IDs are specified in the Predefined Constants List.

 pDigest

    [out] The memory buffer that will receive the message digest/checksum.

    Note. All predefined types are specified in the Predefined Types List.

 pSrc

    [in] A null-terminated string for which to calculate the message digest/checksum.

Remarks

Calculates the message digest/checksum for a null-terminated string. The digest/checksum is retrieved in the pDigest memory buffer.

VB Example

Private Sub MyButton_Click()
    Dim Digest As QHASH_Digest
    'Calculate the digest 
    QHASH_StringDigest MD5_ALGID, Digest, "Hello World!"
    'Show the hexadecimal representation of the digest
    MsgBox QHASH_ConvertToHex(Digest.Value(0), MD5_DIGESTSIZE, True)
End Sub
