Asymmetric Encryption and Key Distribution

---

Hi Team,

I hope someone is able to shed some light on cryptology for me. I'm having a hard time understanding it when it comes down to Symmetric and Asymmetric Encryption and Key Distribution.

I understand that Diffie-Hellmann and RSA are Asymmetric algorithms but are they both used by Symmetric Key for key distribution?

Does Asymmetric key only uses PKI to distribute keys?

Any help is highly appreciated.

Thank you,
Frank

When using Key-Pair (Asymmetric Encryption), The Private Key will never be shared; the public key will be shared freely via a request. This means that the requestor will use that public key to encrypt data to be sent back the the private key holder only.

I mention this because I cannot think of another way to distribute the Asymmetric Key.

Any help is highly appreciated.

Thank you for the explanation.
