*Summary*
Add post-quantum cryptography and a common symmetric AEAD to the set
of cryptographic algorithms available in the Web Cryptography API.
This will enable developers to have access browser-provided
implementations of common quantum-resistant cryptographic algorithms
standardized by NIST. * ML-KEM - 768, 1024 * ML-DSA - 44, 65, 87 *

Pending
*Goals for experimentation*
None
Can you say more why you want to run an OT (or is this a Finch stable
experiment) instead of just shipping?
*Risks*
*Interoperability and Compatibility*
Won't work cross-browser until other browsers implement any of these
new algorithms.
/Gecko/:
Neutral (https://github.com/mozilla/standards-positions/issues/1282) Despite
being neutral, Firefox is shipping anyway
/WebKit/:
Neutral (https://github.com/WebKit/standards-positions/issues/641) Everyone
is neutral because no one likes the Web Crypto API, but everyone
agrees we should add PQC to it.
/Web developers/: No signals
/Other signals/:
*WebView application risks*
Does this intent deprecate or change behavior of existing APIs, such
that it has potentially high risk for Android WebView-based applications?
