Then you can connect through ssh indicating your private key in the command run at he terminal:

ssh -i ~/.ssh/id_rsa4096_mylabel myuser@foo.example.com

xxxxxxxxxx

ssh -i ~/.ssh/id_rsa4096_mylabel myuser@foo.example.com

Note for VHIR:
In order to reach a server through ssh behind a proxy, you need to set the server name at the .ssh/config as usual, plus indicate there the private keyfile that you want to use for the connection to that server. For instance:

Host *.example.com
    ProxyCommand corkscrew proxyserver port %h %p
    IdentityFile ~/.ssh/id_rsa4096_mylabel

xxxxxxxxxx

Host *.example.com

    ProxyCommand corkscrew proxyserver port %h %p

    IdentityFile ~/.ssh/id_rsa4096_mylabel
