ssh-add -K to add keys to Keychain previously in this environment: Intel chipset, macOS Mojave, homebrew OpenSSH_7.9p1, LibreSSL 2.7.3.
Now I got a new Mac with the M1 chip and Monterey. I installed homebrew and OpenSSH (OpenSSH_8.8p1, OpenSSL 1.1.1m) but the
ssh-add -K method doesn't work anymore:
ssh-add -v -K srv_key Enter PIN for authenticator: debug1: start_helper: starting /opt/homebrew/Cellar/openssh/8.8p1_2/libexec/ssh-sk-helper debug1: sshsk_load_resident: provider "internal", have-pin debug1: sk_probe: 0 device(s) detected debug1: ssh_sk_load_resident_keys: failed to find sk Provider "internal" returned failure -1 debug1: ssh-sk-helper: sshsk_load_resident failed: invalid format debug1: main: reply len 8 debug1: client_converse: helper returned error -4 Unable to load resident keys: invalid format
I think the
-K option now functions as the documentation says:
"-K Load resident keys from a FIDO authenticator.", not the previous special feature for macOS. It can't find the sk module so it fails to load the key.
I can load the key now with
ssh-add srv_key but it doesn't work with the ssh config
What's the current practice to make the previous Keychain configuration work with SSH? Thanks for any suggestion!
