Delphi DLL Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.OpaqueVerifyBytesENC method

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

var
success: Boolean;
crypt: HCkCrypt2;
outData: HCkByteData;
bd: HCkBinData;

begin
success := False;

crypt := CkCrypt2_Create();

CkCrypt2_putEncodingMode(crypt,'base64');

//  ------------------------------------------------------------------------
//  The OpaqueVerifyBytesENC method is deprecated:

outData := CkByteData_Create();

success := CkCrypt2_OpaqueVerifyBytesENC(crypt,'base64 encoded p7m',outData);

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

bd := CkBinData_Create();
CkBinData_AppendEncoded(bd,'base64 encoded p7m','base64');

//  If the opaque signature is validated, the contents of bd are replaced with the original data that was signed.
//  
success := CkCrypt2_OpaqueVerifyBd(crypt,bd);

CkCrypt2_Dispose(crypt);
CkByteData_Dispose(outData);
CkBinData_Dispose(bd);
