Both the public and private keys ARE keys... they're just used a<br>
little differently.<br>
<br>
You keep your private key secure, and use it to digitally sign a<br>
message when you want others to be able to check that you actually<br>
sent the message (by using your public key). Others can send an<br>
encrypted message that only you can decode, by encrypting the message<br>
using your public key. When you get the message, you can use your<br>
private key to undo the encryption that was done using your public<br>
key.<br>
<br>
So, in a way, the public and private keys can be thought of as two<br>
pieces of a single, combined key. The software that does the signing<br>
or encryption (using the keys), such as gnupg, pgp, etc., is more like<br>
the lock that the keys fit.<br>
<br>
I hope that helps.<br>
