hex encoded salt SHA1 Hash with Intel GPU on W7

[SG]

Based on Atom's Perl script I have found a working solution! Please find the details if anybody needs the same on Windows without a proper and supported GPU:

Just follow the instruction at the 2012-02-15 16:45 post.

You can download the JTR tool (community-enhanced Jumbo version) from: http://www.openwall.com/john/
Direct link for the right (currently latest) Windows version: http://www.openwall.com/john/g/john179j5w.zip

3 easy steps:
1. The dynamic.conf file needs extended as described in the post
2. to build an input file (sha1-16.in) containing the SHA1 hash (20 byte in hex format). Example: EF63BF26E2382917D96850CCF9632458EE6E6C77
3. Run JTR in command line: john -inc:digits sha1-16.in -form=dynamic_2201

Result:
Loaded 1 password hash (dynamic_2201 SHA1($p) [16-byte null padded SHA1] [SSE2i
10x4x3])
50681318 (?)

Use the "--show" option to display all of the cracked passwords reliably


It always finishes in less then 15 seconds!
