Basically, my goal is to use a single key for everything. I have a GPG key that I imported onto my MacBook, and would like to use that key for SSH authentication. However, despite my several attempts, I cannot get my key to list. I have, for the most part, been following the guide here: https://gregrs-uk.github.io/2018-08-06/gpg-key-ssh-mac-debian/ trying minor variations to see if it would have an impact. But when I run ssh-add -l I get the customary "The agent has no identities."
I notice the guide is relatively old (written in 2018), so has anyone had success with using a GPG key for SSH on Mac? Is it simply a lost cause? Any help would be much appreciated!
Added enable-ssh-support to my gpg-agent.conf file
Added the GPG key keygrip to my sshcontrol file
Added:
export GPG_TTY=$(tty)
export SSH_AUTH_SOCK=$(gpgconf --list-dirs agent-ssh-socket)
gpgconf --launch gpg-agent
to my .zprofile (I suspect this is where the issue lies)
And still nothing after running ssh-add -l

I am really new to Putty and Puttykey generator as I am trying to setup EC2 on AWS. I have managed to install PuTTy on my Mac, and PuTTy works fine, but every time I click on PuTTykey Generator I see a message (please see the snap attached) and no pop up window. how do I get it to work? I have Mac Mojave.
the reason why you use puttygen is to generate the ssh-key pair especially on windows systems. You don't generally need to use putty key generator on mac since Mac OS has a built-in command-line SSH client known as Terminal.
To use terminal, go to Finder and then click the menus Go -> utilities from the top menu. After that find the terminal which supports SSH connections to remote servers.
You can run ssh-keygen to generate an ssh key pair.
ssh-keygen
reference (how to use ssh-keygen to generate a keypair):
https://www.digitalocean.com/docs/droplets/how-to/add-ssh-keys/create-with-openssh/
I am not sure about the reason why you are trying to use puttygen through.
If you simply like to login to your ec2 instance via ssh (using the keypair from ec2), you can use ssh command as below.
ssh -i `~/Downloads/my.pem` ec2-user#[ip-address]
by the way, The reason why you are seeing an output like the one you shared is, when you run puttygen is, it's a command line utility and it's expecting some mandatory command line arguments to be passed.

I'm following this tutorial to set up my first DigitalOcean droplet, and I just generated a Key Pair for Public Key Authentication. After using ssh-copy-id (from Git Bash, since the command isn't available in Command Prompt) to add the key to my Droplet, I can SSH into my droplet just fine from Command Prompt.
However, when I try to SSH from Git Bash, it still prompts me for my password! I've checked, and the SSH keys exist on my Droplet and on my computer. What's the problem?
You can load the key by running ssh-add path-to-private-key
ssh-add /Users/ben/id_rsa
The predefined path is UserHome -> .ssh -> private-key & public-key
/c/Users/USERNAME/.ssh/id_rsa
/c/Users/USERNAME/.ssh/id_rsa.pub
There are restrictions to the name of the file as well as the location. Following are the known filenames that SSH agent will look for that I can think on top of my head:
identity
id_dsa
id_rsa
These names are generally determined by the Type you've used to generate them. Most commonly used is rsa which creates id_rsa and id_rsa.pub.
Also, most Windows user uses Putty as the SSH daemon. It works pretty well. The best thing about that is it has GUI to set the specific private key so it loads that every time without having to do any of the above stuff.

So I am in the process of setting up my own server for the first time using Vultr and I'm following a guide from DigitalOcean. The server is on Ubuntu but I am using Windows 10. I've been doing everything through the console that's logged into my server but now I'm trying to generate SSH keys locally and I'm not quite sure how to do this. I'm pretty new to this and I don't know if this is easily done through Windows 10. The tutorial states..
Generate a Key Pair
If you do not already have an SSH key pair, which consists
of a public and private key, you need to generate one.
If you already have a key that you want to use,
skip to the Copy the Public Key step.
To generate a new key pair, enter the following command at the
terminal of your local machine (ie. your computer):
local$ ssh-keygen
Assuming your local user is called "localuser",
you will see output that looks like the following:
ssh-keygen output
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/localuser/.ssh/id_rsa):"
I can do all this on the terminal I use that's logged in to my server but I can't figure out how to do this locally on my computer. Any help would be appreciated. Thanks.
You could install Cygwin, and get the openssh command-line utilities via its installer. That might be more involvement than you want with Windows.
The easier way would be to install PuTTY, use the puttygen utility to create a PuTTY private key. You can export the public key in openssh format, and use it on your server. (puttygen does the same function as ssh-keygen, using a GUI - but PuTTY's key format is different...)
DigitalOcean has a page on that: How To Create SSH Keys with PuTTY to Connect to a VPS

I just switched from PC to Mac. I had been connecting to a server via SSH using a key on the PC. I thought all I'd have to do to connect on the Mac would be copy the .ssh directory into my home directory and then run the ssh command in the terminal with the right credentials, but it doesn't seem to be working.
When I run this command;
ssh [user]#[hostname] -p 2222
I get this result;
Permission denied (publickey).
In my .ssh directory, there are three .pub files and three key files with no extension. There's also a known_hosts file and a key_backup directory with some keys in it.
Supposing you did copy the correct keys, you need to add your identities to ssh-agent. Try the following:
ssh-add /Users/<username>/.ssh/id_rsa
Where <username> is your username and id_rsa is a private key. It's important to use the absolute path. Upon success, you'll see something like:
Identity added: /Users/johndoe/.ssh/id_rsa (/Users/johndoe/.ssh/id_rsa)
Repeat for every key you want.
As long as you get the proper private key that matches the public key that is stored on the remote platform what you described is correct.
You can add in up to three -v on the ssh command to get more debug information. This can confirm it is using the proper keys. Other things to verify is that the owenership and permissions of the keys on both the Mac and the remote boxes are restricted to the user, and none other.

I installed git for windows and when presented with the option to pick Putty or OpenSSH, I opted for OpenSSH. However, I do have putty installed, and it appears that git caught on to this and is trying to use it. (I have GIT_TRACE=2 in the environment variables)
E:\blah>git push
trace: built-in: git 'push'
trace: run_command: 'ssh' 'git#bitbucket.org' 'git-receive-pack '...
Enter passphrase for key 'C:\putty\my.ppk':
Which is really weird cause that ppk doesn't even have a passphrase. Though the real issue is that it shouldn't be using the putty key, it should be using ~/.id_rsa
This was working right after install, but after restarting the computer it started doing this.
Is there a way I tell git to use openssh without having to reinstall it?
it appears that git caught on to this
Maybe because putty.exe is coming first in your %PATH%.
Check your GIT_SSH environment variable.
set GIT_SSH
If you want to use openssh, you need to set it to git/bin/ssh.exe:
set GIT_SSH=C:\path\to\git\bin\ssh.exe
That should ensure that the push and pull commands look for ~/id_rsa(.pub) keys instead of asking for a putty *.ppk private key store.
