Post: RE: 3des, k1==k3, k1 != k2 kernel
| As a general reference for other searchers:
* My understanding is that k1 != k2 != k3 is feasible because of meet-in-the-middle (https://crypto.stackexchange.com/questions/6345).

Thread: complex md5 salted hash
Post: RE: complex md5 salted hash

Thread: Trying to understand RLI and RLI2 better
Post: RE: Trying to understand RLI and RLI2 better
| The purpose of rli is to diff two lists, and only show the new ones in the new file. It's not a dedupe tool.
For general dedupe, sort -u is your go-to for this. I use this alias (adjust parameters to... |
