quantum computers won't save you as they aren't helping you crack symmetric encryption like AES which is most likely used for an encrypted hard disk.
replyWell if it's bitlocker encrypted I have some good news (potentially) Yellowkey (CVE-2026-45585) is able to bypass it.
replyI was gonna say something like "If it's MSN chats, unlikely Bitlocker even existed at that point" but seems they are actually closer than I remember, only a ~10 year difference when they launched, MSN in 1995 and Bitlocker in 2006.
replyI think me and most of my friends were using MSN all up until the "Windows Live" rename, then I think we started using Ventrilo instead, but looking up the year that was around 2005 sometime.
Ultimately, guess it wouldn't be impossible that their MSN logs were encrypted with Bitlocker after all :) I think I started using TrueCrypt around that same time, seems more likely, I think Bitlocker for many, many years was basically only used by enterprises.
