Hi,

I'm trying to build a suite of classes to generate and then read
encrypted strings. The idea is to have a kind of licensing mechanism in
our product.

A license file will contain some information such as :
- feature,
- ip_addr,
- host_name,
- #lic,
- expiration_date,
- license_key.

The license key would be generated from the other entries and I want
to be able to check this key later in the program. I tried to use
java.security.MessageDigest but without any success.

Could anyone point me to the right direction to achieve this
'licensing functionality' ?

Thank you in advance for any incoming help.

DAvid
