[Question] decode UDID of mobile devices

[FSE 34]

I try to assign MAC address of wifi and Bluetooth of devices that are registered on HC2 for pushing messages. A clever way is to perform that is decoding UDID of device, as it contains all these info.

According to

 the UDID is the following

Does anybody knows a way to perform decoding online as HC2 did not provide hashing ability?

 

Hint: I just found an online API for encoding->

It can help fibaro developers to solve the lack of fibaro to perform hashing !

I found more about UDID. it seems that it is not so easy as it looks

sorry, i can't  understand what you trying to achieve

I try to automatically find the mac address of wifi/bluetooth interface of every device is stored on /api/iosDevices

On /api/iosDevices,  udid are included for every device.  UDID is a encrypted data of serial number of mobile device, ECID, wifi mac address,bluetoothMAC. So decrypting that, I can get the MAC address of device -> find IP address-> check presence of the device by VD. Even better I can scan of Bluetooth mac address if it present.

I know it can be easier to manual entry the data but thinking like @Sankotronic, I like to minimize the user settings configuration on VDs.

Hmm.... you can't revert meat from minced meat again.

 

The definition of a cryptographic hash function includes resistance to preimages: given h(x), it should be infeasible to recover x.

A hash function being "reversible" is the exact opposite of that property.

Therefore, you can have no more a "reversible hash function" than you can have a fish allergic to water.
