Everytime a PowerVU key is updated a line is added in SoftCam.Key #50

Can't we better adapt the line we already have?

The file now grows for ever and the old keys are not needed anymore...

The new method (1 ecm key per transponder) is based on enigma namespace. Unfortunately, this info is not available to other clients, like non enigma2 stbs, pc clients, etc.

So, this means that oscam-emu will have to do different things based on the ecm key it is about to write in the file. This doesn't seem nice.

Also, before this "new method", way more keys were written and the softcam.key file was growing much faster. Now, only 1-2 ecm keys are written which keeps the file size manageable.

Another thing that can be done, and has been suggested previously, is to write new ecm keys in softcam.key only when oscam-emu is restarted or only when the emu reader is restarted. This means that new keys will be stored in memory, like it is done anyway, but they will be not written all the time in the softcam.key.

I wrote code that updates the softcam.key. It grabs the latest key from the bottom of the file, and updates the original ECM lines and on the EMM key line, it modifies the comment to show when that particular emm was last updated, that way i know which EMM keys are being utilized, and which have not. I run the code about once a week, and it keeps my softcam.key clean and easy to keep track.
