Native Secure Enclaved backed ssh keys on MacOS

Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

Hashcat v6.2.6-851 benchmark on the Nvidia GeForce RTX 5090 FE
Nvidia Driver Version: 570.86.10 CUDA Version: 12.8
Hashcat was built from the github master branch at the time of running.
A handful of Whirlpool based modes reported an error due to self-test failures.
The GeForce RTX 5090 was added to the tuning Alias file for this run.

For benchmarking the card and allowing me to release the benchmarks here
The hashcat installation used includes a change to the tuning ALIAS.hctune file to include the RTX 4090 as "ALIAS_nv_sm50_or_higher".
The "Kernel exec timeout" warning is cosmetic and does not affect the speed of any of the benchmarked modes.
Benchmark was run at stock clocks on an Asus Strix 4090.

There are a handful of algorithms failing, mostly appears related to SCRYPT and
is liking a tuning issue or small driver issue that we will need to take a look at.
Otherwise, seems fairly stable.
