ssh2-rs | Rust bindings for libssh2

I have generated a public and a private key using PuTTYgen and added the public key to my GitLab account, but when I try to clone the repository, it still wants a password.

I have read the following instructions from this site

1. Install Putty and related utilities

2. Set system environment variable in Windows(Control Panel\System and Security\System --> and clicking on "Advanced system settings" in the left pane. Then click on "Environment Variables") GIT_SSH=%path_to_plink.exe% (Note plink.exe goes into wherever you installed Putty)

3. Generate a ssh key using puttygen.exe (ssh2-rsa, 4096, comment=GitLab, and set a passphrase)

4. Add key to pageant.exe and the public key to your GitLab profile

5. Ensure you start a new command shell so that git recognizes the GIT_SSH value

6. Try these two commands to check connection first. This should give you a popup window that authenticates connection

7. set Git putty git@gitlab.com:%user%/%repo.git%

Usage:

1. Start pagent.exe from Putty folder
2. Add key to pageant.exe

I still don't understand step 5 and in step 6 I see no shell commands to do the test.

Can anyone help?

Update:

The issue was that I didn't restart my cmd. But now I get this message: The server's host key is not cached in the registry. You have no guarantee that the server is the computer you think it is. The server's ssh-ed25519 key fingerprint is: ssh-ed25519 255 d7:0d:ca:f2:c1:01:46:80:68:4c:5d:e6:d4:52:f9:16 If you trust this host, enter "y" to add the key to PuTTY's cache and carry on connecting. If you want to carry on connecting just once, without adding the key to the cache, enter "n". If you do not trust this host, press Return to abandon the connection. Store key in cache? (y/n)

And it doesn't let me type anything there.
