I have an applet that I believe needs to be signed.
I am reading the HowTo of signing applets at:

The web page says there are three steps.

1) Signing tool (I shall use jarsigner)

2) RSA certificates
My question is do I need to purchase this?
if so how much does one cost?

Quote from web page:

"RSA certificates may be purchased from a ertificate Authority (CA) that supports RSA, such as VeriSign and Thawte."

3) Make applet into jar and bundle
