Intro to sharing

Mircryption uses the Blowfish algorithm for encryption, with a single shared key used for encryption and decryption.

Because of this, it can be difficult to safely communicate keys bewteen two people.  How should you tell a friend about the key for a channel?

One safe way is by using pgp (pgp encryption from within mircryption is being considered, but is problematic because of the high overhead bandwidth for pgp encrypted text).
