What is the performance difference of pki to symmetric encryption?

Question

We are looking to do some heavy security requirements on our project, and we need to do a lot of encryption that is highly performant.

I think that I know that PKI is mu

Perhaps you can add some details about your project so that you get better quality answers. What are you trying to secure? From whom? If you could explain the requirements of your security, you'll get a much better answer. Performance doesn't mean much if the encryption mechanism isn't protecting what you think it is.

For instance, X509 certs are an industrial standard way of securing client/server endpoints. PGP armoring can be used to secure license files. For simplicity, Cipher block chaining with Blowfish (and a host of other ciphers) is easy to use in Perl or Java, if you control both end points.

Thanks.
