Step 3: Sending Encrypted e-mail
There are three ways for Bond o get Q's public key:
1. Q can give his public key to Bond physically, like, say, on a flash disk or some other physical media. This the safest most secure method of communication. Because anybody that tries to decrypt need to know the two keys.
2. Q can e-mail his public key to bond. This is slightly less secure.
3.Q can post his public key on a server, like a keyserver or his website or even Instructables. Now one key is known to the public but the other key is unkown. This exactly half as secure as method 1.
I will post Q's public key here. It also available on the keyserver http://subkeys.pgp.net.
Q's e-mail is email@example.com.
You can send me encrypted messages as practice.
