My main focus is on security and privacy aspects in the areas of business web applications, databases and online games. I like to look further and see the whole picture.

comment Asymmetric vs Symmetric Encryption
Symmetric crypto does depend on the secure exchange of keys. My point is this: Assuming you have such a secure channel, you can use it to exchange public keys as well. Asymmetric crypto does add additional possibilities by involving trusted third parties, but you do not need to use third parties. Other advantages still apply: e.g., You can sign messages to protect them against modifications. You can just pick your private key to decrypt any message sent to you without having to look for the right key. Disclosing public keys is not an issue...

comment Asymmetric vs Symmetric Encryption
If you have a secure channel to share symmetric keys, you can also use that to share public keys. Public/private key crypto adds the additional possibility to attach information about the owner to a public key and let trusted party sign this information.
