Isn't that the entire point of the secure enclave[1]? https://support.apple.com/guide/security/secure-enclave-sec59b0b31ff/web https://support.apple.com/guide/

  If you look at the cryptokit API docs the Secure Enclave essentially only supports P-256. Which is maybe why they didn’t include ECC crypto in the examples.

  The secure enclave is not a general-purpose/user-programmable processor. It only runs Apple-signed code, and access is only exposed via the Keychain APIs, which only support a very limited set of cryptographic operations. Presumably latency for any operation is also many orders of magnitude higher than in-thread crypto, so that just doesn't work for many applications.
