New Video: Weak Hashing Algorithms: Outlook PST file CRC32 password cracking example
In a previous video I explained the basics of cryptographic hashes. Go watch "A Brief Intro To Cryptographic Hashes/MD5" before this video. In this tutorial, I’ll be giving an example of why weak hashes are bad. The example I'll be using is the CRC32 hash that Outlook uses to store a PST archive’s password with. The CRC32 algorithm as implemented by Microsoft Outlook is easy to generate hash collisions for, so even if you can’t find the original password you can find an alternate one that works just as well.
