Cryptographic Agility
Why identity systems need the ability to evolve cryptographic methods
Cryptography evolves continuously. Algorithms that are secure today may become vulnerable tomorrow. Modern identity systems must therefore support cryptographic agility, the ability to update algorithms, key lengths, and protocols without disrupting users or exposing sensitive material.
Incremental Upgrades
In practice, cryptographic agility allows organizations to replace or strengthen cryptography incrementally. A system might upgrade server-side algorithms, rotate keys, or migrate to post-quantum cryptography while leaving existing client-side proofs valid. Without agility, users may be forced to reset credentials or undergo complex migrations whenever cryptography evolves.
Hawcx's Approach to Cryptographic Agility
Hawcx is designed with this principle in mind. Secrets are never permanently bound to a single algorithm or protocol. Device-bound proofs can evolve over time, and the system can adopt stronger algorithms transparently, ensuring users remain protected against emerging threats.
