Steven. Excellent tutorial. I needed to actually see what OpenSSL was about and how the operations were performed. You took me step-by-step and now I know. Great work my friend. Please continue to share the knowledge. Best regards!
I used your videos for my crypto class to get through public crypto section. The class is over but I am back because I want to install SSL Cert on my server. Awsome videos!!!!
Very nicely paced! When I ran the examples on my windows machine using a ported version openssl 1.0.1p, the "pkeyutl -encrypt .. " cmd outputs: "Loading 'screen' into random state - done". Is this a reference to use of a random seed in OAEP to create padding?
heruilin I guess you are correct. RSA encryption doesn't require any random numbers unless it is for padding. The 'Loading screen into random state' looks to be initialising the random number generator (i.e. gathering a random seed).
Dear Sir, Can we implement the openssl statements in client and server model, where client program is encrypting , signing and sending the message in cipher.bin form to server program and the server program decrypts it?
An excellent tutorial! I see the verification step (1 command) as too much magic going on behind the scenes just by performing 1 command. Would it be possible to do it manually step by step: Calculate the SHA digest of the decrypted message (already done), Decrypt the signature with B's public key and actually the output.. then compare this output with the SHA value.

One of the best lectures I've come across. Thanks steven!
You could not have made this more simple and straight to the point. Very well done!
Excellent tutorial. Very to the point, no fluff.
Great job Steve.

I went through lot of fancy documents but could not get the encryption funda, but with your example explanation it was the best. Thank you
Awesome flow of explanation... Loved it..
Cleared mannnnny doubts..
Excellent, Concise & precise tutorial. Thanks for doing this Steven.
One of the best lectures I've come across. Keep up Steven!
Excellent. This tutorial is very helpful. Thank you very much.
Thanks. Clearly explained. Please, we need more & similar tutorials.
Neatly and completely explained. Top class explanation. Thanks.
I don't know who dislike your video
Excellent work.. A tad bit on the longer side but I love it. Thank you
with translated language I really like this
Hello! The generated key is saved in PKCS#8 format or in PKCS#1?

Yes it is applicable to that
I will decompose the RSA of any complexity into multipliers. Fast and not expensive.
What signature scheme does this method use ? could you please help, whats the difference between signing using this method, vs rsautl and pkutil

How can i use salting technique in RSA algorithm, with OpenSSL tools ?
Great tutorial
Does it mean that in the case of symmetric encryption we have to somehow send key to the other side over insecure channel?
If you haven't already try to read on Diffie Hellman key exchange
hello sir can rsa key decode the of set top box card how can sir plz help me
Brilliant 🤩
Excellent explanation. Thanks
Nice explanation.
Thanks
Hi Steven!
Can we see the real prime number, as in decimal?
Go to Brainwallet on google browser. Put Hex to Dec and it’s done!
@@nittla7791 Thanks a lot :)
@@bhavinmoriya9216 your welcome! Make sure is Brainwalletx.github.io :)
Great explanation
How would we verify a jwt signature?
so many things to understand.
Great video
Good one ..thanks a lot
this is awesome
How can i create ev ssl.?🙅
Is PGP better than this?
thank you Sir!
How do you exit out of cat command?
If "cat" is running (e.g. due to very large input) then you can kill the process using "Ctrl-C"
Why would a person use ssl
very nice
awesome
in 2021 but i gotta tell u the 17 dislike is because use a and b instead of alice and bob🤣🤣🤣🤣
