Simplified DES(Data Encryption Standard)(Information Security)

[@91celdia]

That was an amazing explanation. You’ve taught me a lot in this video and made a subject I was struggling with seem so simple.❤

[@made_easy_for_you0000]

Thank you soo much

[@Adwrells]

In 21:55 s0,s1 is noot needed i hope for x0r if done for 3 digit odd nos of 1 are 1 for xor. So technically 011 should be 0. Btw answer is correct 💯

[@khwabvachhani2100]

Yup the XOR should be done with P4 and Left half only, S0S1 not needed

Why are we giving two bits shift for round two? for generating Key2...
As we defined For round 1,2,9,16...we have to give left shift of one bit...

[@lomash_irl]

I have the same doubt and also 2 keys were generated, for 2 rounds of SDES video covers 1 round only

How we can perform in this question?? Please reply anyone 🥺

Yes always given in the qs, P10,p8,Ep,Ip,P4 all are given
