Support passphrase protected ssh keys

[rakuten-JO]

Describe the bug
I want to start a project:

cargo generate --git https://github.com/rustwasm/wasm-pack-template.git

And I get:

Error: Please check if the Git user / repository exists.

Caused by:
    Failed to retrieve list of SSH authentication methods: Failed getting response; class=Ssh (23); code=Auth (-16)

Desktop (please complete the following information):

• OS: [MacOS]
• Version: [Mac Os Big Sur version 11.4]
• rustc --version: rustc 1.65.0 (897e37553 2022-11-02)
• cargo generate --version: cargo generate-generate 0.17.3

Additional context
it is fine in my Windows PC, but i guess it may be the problem of my .git config.

# Personal account, - the default config
Host github.com-personal
   HostName github.com
   User git
   IdentityFile ~/.ssh/id_rsa
   
# Work account
Host github.com-organization
   HostName github.com
   User git
   IdentityFile ~/.ssh/id_ed25519

And I want to know how to fix it?

Interesting, are your keys protected by a passphrase?

As it seems it is using git over ssh even if you've given it a http url.

When you comment out the .gitconfig lines you've mentioned then I guess it does work, right?

Yes, in my Windows PC, I do not have the config file i mentioned above, and it worked, but I do not know the reason of it.
My git config is similar with this ->Multiple Github Accounts on a single Machine:

@rakuten-JO can you please try the approach from the comment below and see if that would solve your issue?

I've tried that approach (git-fetch-with-cli = true in the config.toml for cargo), and it doesn't work for cargo generate. I would have expected it to, but it does not. That would be my feature request, get cargo generate to use/respect this option do do git ops via the cli instead of using libgit2.

Augustus 2023, it works for me ...

stappers@paddy:/tmp
$ cargo generate --git https://github.com/rustwasm/wasm-pack-template.git
🤷   Project Name: foo
🔧   Destination: /tmp/foo ...
🔧   project-name: foo ...

Cargo.toml  LICENSE_APACHE  LICENSE_MIT  README.md  src  tests
stappers@paddy:/tmp
$ cargo generate --version
cargo generate-generate 0.18.3
stappers@paddy:/tmp

@moridinga please retry with latest cargo generate and update this issue.
@rakuten-JO please retry with latest cargo generate, update issue and maybe close it.

Adding the ssh key to ssh-agent should in general work

eval $(ssh-agent)
ssh-add <path-to-your-private-key>
cargo ...

or on mac

eval $(ssh-agent)
ssh-add --apple-use-keychain <path-to-your-private-key>
cargo ...
