Hmm would it be possible to generate ophcrack tables using the provided tools source/bins provided on their site, although they are the source / bins to ophcrack1.0a.

ophcrack tables are completely diffrent from our tables.
even if we could use their source to do some working tables why would we?
firt it would cost time to make a new method and second their would probably not be to much downloads anyway.

No one seems to understand that generating Ophcrack tables is dumb. First off we can only generate tables with character sets that have already been made otherwise will need to modify the Ophcrack code. The format of the Ophcrack tables is optimized for key spaces with a max around 2^43. You can go higher than that with Ophcrack tables but you have to either increase the number of tables or increase the chain length, both of which make it slower. You can only have 4.3 billion starting points per Ophcrack table. We are currently generating tables with 14.0 and 14.7 billion starting points per table. Granted the FRT tables are not optimal but they allow for larger tables. There is a format which is optimal for any table size and allows for check points too, but it is harder to program. Also this was suggested back in April and still nothing has been done about it.
