What does the administrator mean by the public part of the key in SSH format?

Question

SSH

Good afternoon,
I made a website on WP, you need to upload it to the hosting, I asked the admin for access. He answered:
"Please send the public part of the key in openssh format to be added to authoreized_keys
"
What does he want from me and how is this related to my access to him on the server?
Thanks in advance!

Answer 1

He wants to give you SSH access to the server, not with a password, but with a key file.
You need to generate an openssh key, you will have a private key that you feed to Putty or any other Ssh client, and this key has a public part, so to speak public, that you send to it.

Here's how to generate a key, send it id_rsa.pub
Don't send it to ANYONE and hide id_rsa as far as possible, with its help you and will access the server.

Answer 2

The id_rsa.pub file generated by the ssh-keygen utility
