secret-set-value supports _all_ types of secrets, since a secret is
_any_ base64-encoded text. Whether you use that secret information as a
password, a passphrase, and encryption key, or something else is up to
how you have connected that secret to the rest of your virtual machine
management.

I'm not sure where you are getting confused; would it help if the man
page for 'secret-set-value' used the term 'secret' instead of
'passphrase', since 'secret' is the generic term for any base64-encoded
data that must be kept secret? You are welcome to submit a patch
yourself; the man page source is in tools/virsh.pod.
