phpseclib TripleDES ECB问题

Question

I'm currently using phpseclib to encrypt data with tripleDES ECB. After using a third party online encryption tool I realized my encryption result differs from the online tool's encryption result.

My code is attached as follows.

 $des = new \phpseclib\Crypt\TripleDES('MODE_ECB');

 $des->setKey('cba4d056-1fab-4ce6-b61f-42e92e0dd563');
 $plaintext = 'abcabcabc';

 echo base64_encode($des->encrypt($plaintext));

The online encryption tool results are as follows.

What am I doing wrong with the library function that gives me a encrypted message different from the online tool shown?

Answer 1

Your constructor is wrong. Do this instead:

$des = new \phpseclib\Crypt\TripleDES(\phpseclib\Crypt\TripleDES::MODE_ECB);
