Oracle 10G & Lower - DES($salt.$pass)

Just wanted to see if there was any possibility of getting support for Oracle 10G and lower hashes implemented in oclHashCat/cudaHashCat. Oracle 10g uses the DES($salt.$pass) hash format, where $salt is the account username.
Thanks!

Just realized that DES takes a 56-bit input, so my understanding of the Oracle hashing algorithm wasn't 100% correct.
Here are a few good resources that describe the process correctly: http://jchblue.blogspot.com/2010/04/orac...rithm.html http://freeworld.thc.org/papers/thc-orakelsniffert.pdf http://groups.google.com/group/comp.data...7a977fb6ed http://www.red-database-security.com/whi...words.html

OK, got the first version working!
That damn document from above -> http://freeworld.thc.org/papers/thc-orakelsniffert.pdf I lost nearly a week till I realized that this block is invalid: Quote:// first DES CBC See here: Quote:root@thumbstone:~# xxd data However, got it working. Some example output following. Finds the pass: Quote:root@sf:~/oclHashcat-lite-0.10# ./oclHashcat-lite64.bin -m 3100 C648972D2BE43FA4:SYS --pw-min 5 --quiet Benchmark on hd7970 (stock clock): Quote:root@sf:~/oclHashcat-lite-0.10# ./oclHashcat-lite64.bin -m 3100 aaaaaaaaaaaaaaaa:a --pw-min 7 -n 800 --gpu-loops 1024 --runtime 30 |
