DES? EFF did their famous DES cracking in 1998, and Wiener hypothesized a $1M USD machine to crack it in 7 hours in 1993. That’s not a great. But, AES and triple DES didn’t come out until 1998..
CBC mode? That’s rough for disk encryption due to sequential encryption. But wait, LRW, ESSIV (the next steps before XEX and XTS) hadn’t come out yet..
This person created an encrypted filesystem in almost the perfectly least optimal year in terms of the longevity of the cryptographic primitives they used. That’s so sad :P
