Secret keys can be shared/exchanged using algorithm such as ECDH. Another way to share a Secret Key is by using Public Key Encryption. I wanted to keep this video as simple as possible for the general audience. I will surely plan a separate video on safe key transportation. Thank you.
Thanks for the detailed explanations. Completed keytool playlist and going through openssl. Could you please create a video on comparing JDK : keytool and openssl side by side ? Also, OpenSSL vs LibraSSL , explain on Heartbleed OpenSSL bug Mac if feasible.
I'm happy this video was useful to you. What you asked for is one of the topic I will cover in future. LibreSSL vs BoringSSL vs WolfSSL vs OpenSSL is going to be one of topic I will cover in future. I'll try to post that video before 2022 ends. Currently I'm in a process of relocating to another country so I will not have access to me recording/editing computer for few weeks.. I appreciate your patience.
In the case of insecure communication, do you send both the message and its hash? If that is the case what is the point of hashing in the first place? If only message is sent leaving out the hash, Jill can verify the message by hashing and comparing the two hashes. If the message is intercepted and modified, the hash would be completely different.
@@gouthammarkandeya4158 OpenSSL v1.1.1 does not have any command to do kdf. However OpenSSL API does have functions to perform KDF programmatically. OpenSSL v3.x does have a command to perform KDF along with API supporting this operation programmatically. Here's a link for your reference. www.openssl.org/docs/man3.0/man1/openssl-kdf.html I can't help you beyond this; You'd have to wait till I make a video on this topic..Thanks.
It's a good explanation of authenticated hashes, it would be good to include how to share the key, and reference to few applications helps

Yamamoto from bleach? I'm not that old.. 🙂

Message is required to be sent with its hash. If you just sent a message (without hash) to Jill then what is she going to compare it with?
Hello, Do you have a video on HKDF? I'm looking for OpenSSL command to run HKDF expand and generate OKM
Nope, I don't have any video related to Key Derivations.... not yet.
@@CyberHashira Thanks for the quick response, can you give some pointers for OpenSSL command to run HKDF command
@@CyberHashira Thanks, can you give some pointers for OpenSSL HKDF commands
