Look! Everyone on here. From this video, I realized if you don't understand any form of instruction, complex or simple (math, science, logic, etc) it is not your fault. The burden of you understanding a section of instructions or lesson lies largely on the person teaching. Thank God for the internet. If something is not too from your instructor, try learning it from other sources until it is clear. It worked for me. Cryptography has been like a mystery over my years in cyber security. THIS VIDEO right here proves my theory. "It wasn't my fault". @Satish CJ! You've made my years! 🤣 For the rest of my life, I can explain DES to anyone in my sleep! Sorry, this is a long comment.... but AMAZING.

Thank you so much sir!

Thank you!

Really helpful!!

Amazing!

in 8:53 the second part of the key+ should be 1110011 instead of 0110011

the permutation table is provided in the exam or do we have to carry the tables with us.....and is this permutation tables is common for all problems or different

Is the value of PC-1 table and pc-2 table constant or given?????? additionally the value of iteration to left shifts is it constant ??? please i need your help to understand!

Sir could you please explain the design principle of s box & p box

bestest

BBS WALO YAHA ATTENDENCE LAGAO

I need help in speck lightweight encryption and key generation thank you so much

Sir,These pc tables are of pre-defined or else we can take of our own

Aced it.

sir should we learn all pc tables???this is my doubt sir

Question: if there are 64 bits in the key and only 56bits on the PC1 matrix, do the remaining 8 bits on the key just not get used?

Sir please share DES notes

How to write pc 2

Sir, I need the powerpoint file, please

What are the steps for DES decryption?

Sir, who invented this? Please let me know 😡

That's literally the best tutorial on DES I've ever seen on youtube. So practical and very detailed. thank you so much sir. I highly appreciate your work
