Must be used in conjunction with the server-side sshpop plugin
The sshpop
plugin provides attestation data for a node that has been
provisioned with an ssh identity through an out-of-band mechanism and responds
to a signature based proof-of-possession challenge issued by the server
plugin.
The SPIFFE ID produced by the server-side sshpop
plugin is based on the certificate fingerprint,
which is an unpadded url-safe base64 encoded sha256 hash of the certificate in openssh format.
spiffe://<trust_domain>/spire/agent/sshpop/<fingerprint>
