from the description of the visa document you need to tighten up access to a certain level of protection. Solaris comes with Kerebos. Also ssh provides a good key management system. VPN products use encrypted tunnels. If you are trying to use key encyption via a web application then I would look at the native hardware encryption that comes with the niagra series of servers. They are reasonable in price. Could you not splice a non java encryption method into the program?
