    Fantastic lectures, professor Paar! Just want to thank you for the excellent effort you put into these! What you say at

    Correct me if I'm wrong but this is actually SHA-0. SHA-1 requires a circular shift to the left by 1 position of the "words", Wj (16<=j<=79).

    This was the most informative and clear lecture of the series so far (going through in order). Professor Paar's accent and cadence are particularly engaging (he should consider radio or film if lecturing get too booooring (said in the Paar style/cadence/idiom) for him).

    Thank you! This series was instrumental in helping me pass my cryptography module at KCL. I'd read their stuff and come here to have it make sense. Then I went back and just made sure I knew their notation for the algorithms.

    Unfortunately there is a little mistake in the last formula for computing W_j: After XORing the four previously computed Ws one has to do a rotation to the left by one bit.

    Thanks Professor .Does Sha1 specifies anything about IV (ie : h0 to be used when compressing x1 ) ?

    SHA-1 is now dead but this lecture is still valuable for learning purpose
