If you choose names that aren't part of the policy, you can always
supplement the policy with your own rules. The existing policy in
CentOS7 is pretty flexible, it should mark files with the following
patterns as sshd_key_t:
/etc/ssh/ssh_host.*_key,
/etc/ssh/ssh_host.*_key.pub,
/etc/ssh/primes
In CentOS6, the policy is for:
/etc/ssh/ssh_host_key.pub,
/etc/ssh/ssh_host_rsa_key.pub,
/etc/ssh/ssh_host_dsa_key.pub,
/etc/ssh/primes,
/etc/ssh/ssh_host_key,
/etc/ssh/ssh_host_dsa_key,
/etc/ssh/ssh_host_rsa_key
... which is a bit less flexible.
If you want to supplement the policy, you can run:
semanage fcontext -a -t sshd_key_t "/etc/ssh/whatever_keyname_I_want"
... to update the local policy with your own rules. Then a
`restorecon` will choose the correct type.
