GPG: the Best Free Crypto You Aren't Using, Part II of II

Mick picks up where he left off with GnuPG and gets even more paranoid with signing and verifying keys.
Conclusion

Thus endeth our two-month tutorial on basic GnuPG use. This is one tool that many, many more of us should be using than presently do. So please, go forth and encrypt. Specifically, encrypt using keys that have been signed and verified by people you know.

By the way, I'll be off next month working on a book on Linux security for O'Reilly & Associates. Fear not, however; an able substitute will be found to handle the column while I'm gone, and I'll be back the month after that. Cheers!
