How to use this project on WSL

TBD TL;DR version for now: Since WSL has no access to security keys, you can use a windows ssh-sk-helper and set your WSL OpenSSH to interact with keys through it. You need to run something like this inside WSL:

SSH_SK_HELPER=/mnt/c/gitforwindows/usr/lib/ssh/ssh-sk-helper.exe SSH_SK_PROVIDER=c:/gitforwindows/usr/lib/winhello.dll ssh-keygen -t ecdsa-sk
SSH_SK_HELPER=/mnt/c/gitforwindows/usr/lib/ssh/ssh-sk-helper.exe ssh -oSecurityKeyProvider=c:/gitforwindows/usr/lib/winhello.dll user@host

  • Path to SSH_SK_HELPER should be a Linux WSL address but SSH_SK_PROVIDER should be a Windows address.

  • Any DLL dependency ssh-sk-helper needs should be in Windows PATH env variable or they need to be copied in same folder where ssh-sk-helper is(having them in WSL PATH env variable won't help).

  • ssh-sk-helper in Windows and OpenSSH in WSL should use same protocol. So far, all released versions of ssh-sk-helper have same protocol.
