Very hot commit, continue reading here:
This is a test commit using buffers large enough to handle both passwords and salts up to length 256. It requires changes to the kernel code, which is not included in here. It also requires some of the host code to be modified. Before we're going to modify kernel code to support the larger lengths I want to be sure of: 1. Host code modification is ok (no overflows or underflows) 2. Passwords and Salts are printed correctly to status, outfile, show, left, etc. 3. Performance does not change (or only very minimal) This is not a patch that supports actual cracking both passwords and salts up to length 256, but it can not fail anyway. If if it does, there's no reason to continue to add support for both passwords and salts up to length 256.
