Can we use the server response to start cracking to? - - john GPU support for kerberos etype 18 - - a tool to pre-compute PBKDF2 etype 18 AES keys (preferable via GPU) - input: wordlist, john rules, salt, iteration count - output file which contains the AES keys for the given wordlist (with rules applied), salt and iteration count - - john support to crack etype 18 with precomputed AES keys (instead of passwords) using the above pre-generated AES key list as input (I omitted features related to downgrade attacks as they are not implemented in john) thanks! -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJQugBVAAoJEJeRHQyF0ukM60sQAIlPwDzAXhkXeQrNizhk0BZ0 2cya0WZEYHXqApCAZts07X/4A+U+OXQknyK2wwgRbWxdJfCw8WzTd06AIU8YUiGq J5pE+vU+03tVy+7m5qx79CyTo5xuEluHxojma6FqTypQHZLqMOucJtaPYuA4eyj3 Z4X7YnnWx2o8jeVfpKb+XPLxf9+SCM3Pe2v8x4jvo40VwgfkOuuC7qWUQXM13E4H TWhn/UB0bnMJDzOScW1J/NRZOeKBb54oQXHJvz7SALhzLZU/uKGZzaCXJtmbnHEr nHySR1AilXTFig4cYYTeQ3Us6IYk8tss2SacOc9E49W2wd8BH70XHwHaCNp6ioW1 WDo39rs4HZW2Pi15x8zMBGeH56tCcvKoXmhUUlkUJCIam7fBtpnTr/9zMnv3qwfr G/+X/RG0Uppn+gVy4x4KXCo8npeQo/9Gt5Biy22/lzTx5T6EONkMJ3U+8Szn5NFm yG9qw4k8cTDjGT2C30pTx6UOvDsOKBJ63AEjLGQgAKJ509mb7pZ1s3EzIUTlYvFZ S8t8w4n1jiBuow57nW19kS5ZtFsHtctByncSLfnBC04qwhcUvLoSbb2QCf+9ov1V ecxC/+8BOtQr8oXl0yoyDnt7tWMwhGRHOqRK0ZBrew7vVnRsnTtzJLY3yipkgc1D kcyGudLOnZq2A63LoypD =CnDK -----END PGP SIGNATURE-----
