An asymmetric cipher is an encryption scheme using a pair of keys, one to encrypt and a second to decrypt a message. This way the encrypting key need not be kept secret to ensure a private communication. Similarly in public key authentication, the verification key can be public and the signing key private.

RSA using 2 as a public exponent
I'm failing to see why 2 can never be used and what weaknesses would be associated with doing so.
There's a similar question asking why it has to be in the form of $2^n$+1 but why not $2^n$
