After optimising its rainbow tables of password hashes to make use of SSDs Swiss security firm Objectif Sécurité was able to crack 14-digit WinXP passwords with special characters in just 5.3 seconds. Objectif Sécurité's Philippe Oechslin told Heise Security that the result was 100 times faster than possible with their old 8GB Rainbow Tables for XP hashes.

The exercise illustrated that the speed of hard discs rather than processor speeds was the main bottleneck in password cracking based on password hash lookups.
