WebCryptography is the practice of protecting information through the use of coded algorithms, hashes, and signatures. The information can be at rest (such as a file on a hard drive), in transit (such as electronic communication exchanged between two or more parties), or in use (while computing on data).

This lack of structure allows them to be plausibly quantum resistant despite Shor's algorithm, while still having a number of applications. The most famous example of group actions are built from isogenies on elliptic curves.
