Delphi DLL Requires Chilkat v11.0.0+

Workaround for the deprecated EncryptBytes and DecryptBytes methods

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

var
success: Boolean;
crypt: HCkCrypt2;
unencryptedBytes: HCkByteData;
encryptedBytes: HCkByteData;

//  ------------------------------------------------------------------------
//  The EncryptBytes and DecryptBytes methods are deprecated and will eventually be removed.

unencryptedBytes := CkByteData_Create();

encryptedBytes := CkByteData_Create();
decryptedBytes := CkByteData_Create();

success := CkCrypt2_EncryptBytes(crypt,unencryptedBytes,encryptedBytes);
success := CkCrypt2_DecryptBytes(crypt,encryptedBytes,decryptedBytes);

//  ------------------------------------------------------------------------
//  Replace the above CkByteData usage with the following code:
//  (Chilkat is moving away from using CkByteData)

bd := CkBinData_Create();
CkBinData_AppendEncoded(bd,'AABBCCDDEEFF01020304','hex');

//  in-place encrypt
CkCrypt2_EncryptBd(crypt,bd);

//  in-place decrypt
CkCrypt2_DecryptBd(crypt,bd);
Memo1.Lines.Add('Decrypted: ' + CkBinData__getEncoded(bd,'hex'));

CkCrypt2_Dispose(crypt);
CkByteData_Dispose(unencryptedBytes);
CkByteData_Dispose(encryptedBytes);
CkByteData_Dispose(decryptedBytes);
