Introduction to Encryption

Questionnaire

Which is the currently most used symmetric encryption system on the Internet?

Triple-DES
DES
RC4
AES

The advantage of symmetric encryption in comparison to asymmetric encryption is in general:

It is more secure.
It is faster.
It allows for an easier key exchange.

Although the public key can be read by anyone, why does this fact alone not solve the key exchange problem?

Exchanging public keys is not enough to technically encrypt data.
Public keys are too big to be transferred over the Internet.
A public key contains no identify information.
Public key storage formats can be incompatible.
