IPSec AES 256 encryption in Windows XP with Service Pack 3?

Does IPsec in Windows XP Sp3 support AES-256 encryption?

Update:

  1. Windows IPsec FAQ says that it's not supported in Windows XP, but maybe they changed it in Service Pack 3?

    Question: Is Advanced Encryption Standard (AES) encryption supported?

  2. origamigumby, please specify where, because I cannot find it.
Solution

  • I'm using Windows XP SP3. When I add a new IPsec filter rule, the only options for ESP I get are DES and 3DES, so the FAQ is correct - there is no support for AES prior to Windows Vista.
