C'est pour faire quoi ?

Create your ssh key
Very basic creation (rsa is required by git server):
ssh-keygen -t rsa
Tips: use -C to identify this public key for yourself or others.
Typically:
ssh-keygen -t rsa -b 4096 -C "${USER}@$(hostname)"
Public key default location: ~/.ssh/id_rsa.pub
If you need to create a ssh key in a script you need to use
ssh-keygen -t rsa -b 4096 -C "your comment" -f "${HOME}/.ssh/my_id_rsa" -N ''
You can use comment field to identify your keys, like this:
For default ssh key
You probally whant to use defaut file name for your key:
ssh-keygen -t rsa -b 4096 -C "${USER}@${HOSTNAME}" -f "${HOME}/.ssh/id_rsa" -N ''
For a custom ssh key (design for a service, or any special use)
In that case it's a good idea to track service name, and user name of service, in key file name and in key comments:
APP_USER='testuser' # User for the application
APP_NAME='gitlab' # Name of the application
ssh-keygen -t rsa -b 4096 -C "${APP_USER}_${APP_NAME}@${HOSTNAME}" -f "${HOME}/.ssh/${APP_USER}_${APP_NAME}_id_rsa" -N ''
Manage multiple ssh keys
You might need to add the key
eval `ssh-agent -s` # only once per session.
ssh-add [file ...]
To view know keys on your system, use:
ssh-add -l
