Thanks Lukas

Is this in John 1.7.9-jumbo7? I've been trying to use this with the output from DaveGrohl (dave -j <username>, but I get the error:

No password hashes loaded (see FAQ). 

The output looks like its correct, but I know that the author of Dave was taking a guess at the format you'd need when he implemented the hash extraction. I get the following from Dave:

user1:$ml$18975$b8ffe5381673a3dce4f2fa7a4e2bb465ffba6b1706f1350e7839d6aac7dbde56$bd0ada8614a5cdf9040f49d6ecd499a8eaf54d9361f5dc0a47da5aa0ddd7ea0c844c3552099e50e98fa9b3637b0ff02c584ac55bd06c9bc0660ba6a245cdea8f2feeb83556faf718c0f389c8a036bdfd9d481569ec02bb62f0b8f2354a9e197f389ea064f0921f282b88737d988135f37a1b56b5e72058ca19edb52c96053eb9

What should the format be for John, or do I need to tell it which hash to use manually?

Thanks

Bruce
