The keygen generates a key based on your system’s perceived HWID - this is sort of how Denuvo operates as well. Keys generated on one system won’t work on another. I don’t know why there’s an Android version though.
Edit: From a glance at their website it seems like this newer 80_PA is based (only?) around offline activation codes (Request Codes), where you can take a code generated from a Securom program, plug it into the keygen, and put the Unlock Code back into the program. This would work on Android/wherever as it doesn’t directly rely on the HWID being visible. The older 80_PA version worked based off of system HWIDs, and generated keys without needing request codes. The older 80_PA does include some request code decryption tools but as far as I can tell doesn’t directly translate a request code into an unlock code?
