oclHaschat only implements a single block of sha256, therefore total input (salt + plain) cannot exceed the size of one block.

Thread: SHA256 bug when salt is really big?
Post: RE: SHA256 bug when salt is really big?
Correct me please if I am wrong:
Password: 1234567 = 7 characters
Salt: [@36 Dirty, Ugly and Filthy old men!#] = 38 characters
So, 7+38= 45 < 55
Isn't (salt+plain) less than 55? |

Thread: SHA256 bug when salt is really big?
Post: RE: SHA256 bug when salt is really big?
I apologize if my initial posting was not clear enough:
when trying to find the password just for 1 hash (with the long salt) it works fine!
So, in your example you have in your hash file "examp... |
