The concepts are very well explained. Loved it and understood it thoroughly as well.

[@mma-dost]

great video college teachers just show ppts and read out those seems like they chose the profession of teaching because of making money not because they want to teach.

Awesome!!! but too much echo n dark background. great if the video is re-recorded... thx

[@lecturesbyshreedarshank8977]

Yes .. Have taken care of it in the recent videos including s-DES .. decryption...ua-cam.com/video/HDg9qxCfj3c/v-deo.html will re-record in the near future...

[@rajalakshmigs2049]

Well cleared sir . But one doubt sir
How to create p10 and p8 sir .what is the order of these sir ?

[@lecturesbyshreedarshank8977]

As such they are predefined such that Reversible mapping exists....

[@rajalakshmigs2049]

@@lecturesbyshreedarshank8977 okay sir

[@youtube_user_rrakagps]

Sir in books for LS2 they perform two shift operation on bits after P10 not LS1. Which is correct ?

[@jzzopozzo6510]

Are those P10, P8 etc. already known or randomly generated?

[@lecturesbyshreedarshank8977]

They are known , and remain the same in the case of s-DES - Encryption /Decryption process sub key generation..

[@devillove9334]

P8 means till 8th round?

[@sameerahmed2249]

Generate the cipher text while using the S-DES technique provided that an 8-bit plaintext input 00110110 is provided and a 10-bit key 1110000010 is used. How to solve this one anyone knows ??

[@lecturesbyshreedarshank8977]

It's very easy..follow the steps provided in lecture videos Part 1 & 2

[@lovefrommars7468]

Sir could u pls provide java/python code for this algorithm

[@since_Together]

how u write the p10 values sir

[@lecturesbyshreedarshank8977]

They are predefined...
