srdutil is a command line tool developed by Apple for use with their Security Research Device. It is used to manage, restore, and install software developed by security researchers and hackers. It was developed as early as 27 August 2020 and is in a private Github repository.
Purpose of Command
The srdutil command is used to "Checkin" with the Security Research Device. It is also speculated that it can restore the device, but fails due to a missing dylib called "libMobileRestoreInternalExtensions", which is likely used to reinstall the SRD extensions that make it work..
Version (As of 27 August 2020)
Security Research Device Utility Version 1.0.0: Sat Aug 27 02:17:12 PDT 2022; root:srd_tools-29~1707/srdutil/RELEASE_X86_64RELEASE
Checkin
The command sends a request to the SRD Checkin API with an authentication token to srd-checkin-api.apple.com (will return bad request if using a test token). The command asks for a user in the field SRDUTIL_CHECKIN_USER for the user to request a Checkin with their device.
