They are unique cryptographic codes for your device and a particular iOS version. Apple servers verify these codes during software updates or restores. SHSH blobs saved from previous signing windows can be used for certain techniques to downgrade iOS 18/17/16 to older versions (not officially supported by Apple).
By possessing the valid SHSH for a desired firmware version, 3uTools can potentially bypass Apple's standard signing window, enabling restoration or downgrade procedures outside of the officially supported options.
