Delphi DLL Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.SignBytesENC method

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

var
success: Boolean;
crypt: HCkCrypt2;
cert: HCkCert;
path: PWideChar;
inData: HCkByteData;
base64_sig: PWideChar;
bdIn: HCkBinData;

begin
success := False;

crypt := CkCrypt2_Create();

cert := CkCert_Create();
//  ...
//  Load the cert from a source such as a .pfx/.p12 file, smart card, USB token, Apple keychain, Windows certificate store, etc.
//  
success := CkCrypt2_SetSigningCert(crypt,cert);

CkCrypt2_putEncodingMode(crypt,'base64');
CkCrypt2_putHashAlgorithm(crypt,'sha256');

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

//  ------------------------------------------------------------------------
//  The SignBytesENC method is deprecated:

inData := CkByteData_Create();
CkByteData_loadFile(inData,path);

base64_sig := CkCrypt2__signBytesENC(crypt,inData);

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

bdIn := CkBinData_Create();
CkBinData_LoadFile(bdIn,path);

base64_sig := CkCrypt2__signBdENC(crypt,bdIn);

CkCrypt2_Dispose(crypt);
CkCert_Dispose(cert);
CkByteData_Dispose(inData);
CkBinData_Dispose(bdIn);
