Program GenKey;
{
This is a sample programme using RkPlus. It is a sample of a registration
key generation programme that would be used by the programmer to create
registration keys to be distributed to registered users. The user would
then enter the registration key into a registration programme (such as
Register or Brand) to create the key file. The key generation programme
itself would NOT be distributed, as it would allow users to generate keys.
This sample can create a 1 or 2 month limited use demo key, a 1 year
registration key or an unlimited registration key, for the Sample1, Sample2,
Sample3 and Sample4 programmes.
GenKey uses the example encoding unit Encode.
