Re: What can WPA/WPA2 use for Encryption

Jon & Israel

Thanks so much for your replies & the links - you've both helped me  
understand the whole thing alot better

Unfortunately the encryption will be between 2 "microwave" APs so  
unless they have a RADIUS server built in u guess I'm stuck with PSK &  
AES at best

Just one question - I understood from Chris AES is the only encryption  
method available with WPA - so how then could I use PKI instead. Or  
would PKI take the place of PSK & if so, how ?  Isn't PKI escentially  
"encrypt with A, decrypting with B" where A is public & B is  
confidential. Or am I missing a trick here ?

Tks
Martin

Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, 
install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are 
highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
