// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// You can verify a signed DLL or EXE.
path := 'c:/someDir/something.dll';

codeSign := CkCodeSign_Create();

// If successful, the signature is removed from the EXE or DLL file.

if (success = False) then
  begin
    Memo1.Lines.Add(CkCodeSign__lastErrorText(codeSign));
