Hmm, I'd start with either of Schneier's books: _Applied_Cryptography_
(http://www.counterpane.com/applied.html) or the newly released
_Practical_Cryptography_ (http://www.counterpane.com/book-practical.html).

Counterpane also has an online bibliography of over 1400 papers and
articles on Crypto (Got to be better than the sci.crypt archives)
available at http://www.counterpane.com/biblio/ . I'd also check the
monthly CRYPTO-GRAM newsletter (also available on the same site).

Extensive list of PKI links at http://www.pki-page.org/

And check Keith Ray's OpenPGP page at
http://www.nullify.org/openpgp.html, some of the links there may just
answer your questions.

Hopefully this is enough to get you started. Keep us posted, would you?
