the private key used for authentication.**step ssh config** configures SSH to be used with certificates. It also supports
flags to inspect the root certificates used to sign the certificates.

This command uses the templates defined in step-certificates to set up user and
hosts environments.

## EXAMPLES

Print the public keys used to verify user certificates:
'''
$ step ssh config --roots
'''

Print the public keys used to verify host certificates:
'''
$ step ssh config --host --roots
'''

Apply configuration templates on the user system:
'''
$ step ssh config
'''

Apply configuration templates on a host:
'''
$ step ssh config --host
'''

Apply configuration templates with custom variables:
'''
$ step ssh config --set User=joe --set Bastion=bastion.example.com
