also if this helps:https://docs.google.com/spreadsheets/d/10xL4QgSZuTYyQsDFod7g...
the question is: do you know approximately a well known plaintext from a ciphertext?
yes but no endianness, we have about 121,000 plain->cipher. Well we are not that sure that it was des or 3des:https://news.ycombinator.com/item?id=25302558 https://news.ycombinator.com/item?id=27036740 https://news.ycombinator.com/item?id=27611436
What’s the difficulty level of brute forcing the DES key with a GPU?
i dont have a dedicated gpu its a laptop gpu (hp probook 640 g1) from 2016.
I’ll trade GPU time to brute force the key for a copy of the archive for the Internet Archive, assuming the key is of a length that can be brute forced in a reasonable amount of time.

you mean the spreadsheet or the videos themselves? Ill check with the people im with. Just download this meanwhile:https://docs.google.com/spreadsheets/d/10xL4QgSZuTYyQsDFod7g...
yeah you can
