For Privacy/Coolness, Use PGP
If you want to make sure that no evildoers eavesdrop on email that you send to me, you can use
PGP (Pretty Good Privacy) encryption.
Or, you can just encrypt your messages to be amazingly cool.
Basically, you can use my public key to
encrypt messages so that only I can decrypt them (even you can't
decode them). To get a more complete explanation of PGP, just click on
this link to get the PGP
documentation or jump directly to a
quick overview. PGP uses the RSA algorithm; to get tons of
information on RSA and public-key cryptography, click here. (Did you know
that my CS advisor, Ron Rivest, is the
"R" in "RSA?" Cool beans, huh?)
PGP encryption/decryption software is free and is available on the Web
from PGP, Inc. and also at
this MIT site, or from
here if you are outside the US. To find out other
people's public keys, you can try this
public key server. If you use an Apple Macintosh, there is a page on
I have very few "signatures" on my public key. The reasons for this are:
- I don't know many people who have public keys and could "sign" it.
- I am not very worried about someone cooking up an elaborate scheme to publish a fake public key in my name. I just would rather not have anyone randomly sniffing the net intercept my private correspondence.
Here is my PGP Public Key:
-----BEGIN PGP PUBLIC KEY BLOCK-----
Version: PGP for Personal Privacy 5.0
-----END PGP PUBLIC KEY BLOCK-----
