Thank you so much for making this video! This is one of the best explanations of a hash length extension attack I’ve seen and I’ve been pouring through tons of videos and blog posts trying to wrap my head around it. Will recommend to anyone I know interested in going through CryptoPals where this is one of the challenges (including implementing this attack in code).
