Delphi DLL Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.SignString method

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

var
success: Boolean;
crypt: HCkCrypt2;
cert: HCkCert;
textToSign: PWideChar;
outData: HCkByteData;
base64_sig: PWideChar;
bdSig: HCkBinData;

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);

//  Sign the utf-8 byte representation of the text.
CkCrypt2_putCharset(crypt,'utf-8');

textToSign := 'This is the text to sign';

//  ------------------------------------------------------------------------
//  The SignString method is deprecated:

outData := CkByteData_Create();

success := CkCrypt2_SignString(crypt,textToSign,outData);

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

CkCrypt2_putEncodingMode(crypt,'base64');
base64_sig := CkCrypt2__signStringENC(crypt,textToSign);

//  If you want the binary bytes of the signature decoded from base64.
bdSig := CkBinData_Create();
CkBinData_AppendEncoded(bdSig,base64_sig,'base64');

CkCrypt2_Dispose(crypt);
