I’ve built my own security using RIP serial numbers; can I still use it with LDK?
This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP.
Yes, the RIP still has a RIP serial number that can be read using the PostScript serialnumber
operator, which is accessible to your skin code. Your code must be able to handle numbers larger than 65535.
