Delphi DLL Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.HashFile method

Shows how to replace the deprecated HashFile method. (Chilkat is moving away from the use of CkByteData.) Delphi DLL

var
crypt: HCkCrypt2;
path: PWideChar;
outData: HCkByteData;
hex_hash: PWideChar;

begin
crypt := CkCrypt2_Create();

CkCrypt2_putHashAlgorithm(crypt,'sha256');

path := 'c:/someDir/example.dat';

//  ------------------------------------------------------------------------
//  The HashFile method is deprecated:

outData := CkByteData_Create();
success := CkCrypt2_HashFile(crypt,path,outData);

//  ------------------------------------------------------------------------
//  Workaround.
//  (Chilkat is moving away from using CkByteData)

CkCrypt2_putEncodingMode(crypt,'hex_lower');
hex_hash := CkCrypt2__hashFileENC(crypt,path);

CkCrypt2_Dispose(crypt);
CkByteData_Dispose(outData);
