NAME         top

       systemd-report-sign-plain@.service, systemd-report-sign-
       plain.socket, systemd-report-sign-plain - Sign system reports with
       a local software key

SYNOPSIS         top

DESCRIPTION         top

       systemd-report-sign-plain@.service is a system service that signs
       system reports generated by systemd-report(1). It is a signing
       backend for the --sign= logic of that tool: it implements the
       io.systemd.Report.Signer.Sign() Varlink method and is reached via
       a socket linked into the /run/systemd/report.sign/ directory,
       named plain.

       The service is socket-activated (one instance per connection) via
       systemd-report-sign-plain.socket, and signs the digest passed to
       it with a local software key. Signatures are made with the Ed25519
       (EdDSA) algorithm.

       On first use a key pair is generated automatically and stored
       below /var/lib/systemd/report.sign.plain/: the private key in
       local.private (PKCS#8 PEM, readable only by the root user) and the
       public key in local.public (PEM, world readable).

       The public key is also exported as a system report metric.
