Thread: Hex ch and small problem
Post: RE: Hex ch and small problem
| It's not a buffer overflow, and it's not the number of instructions. The issue is hashcat stores keyspace as a uint64 which means the maximum value it can store is 2^64 -1. It cannot work with numbers... |

Thread: md5 hashing emails - that's dumb, right?
Post: RE: md5 hashing emails - that's dumb, right?
| In this context (assuming the donors or beneficiaries or whomever are intended to be kept confidential) it is dumb to use MD5, yes. They should be trivial to crack.
You wouldn't use a mask. You'd ... |
