NAME

       rootsign  -  cryptographically sign standard input with a private/public keypair unique to the local root
       user

DESCRIPTION

       rootsign is a program that operates on standard input, cryptographically signing it with a private/public
       keypair  only  accessible by the local root user, and outputting the result on standard out, suitable for
       piping to mail(1).

       A new key will be generated on first use, and is written to /var/lib/rootsign/$KEYID.rsa.pub  for  import
       by other users into their keyring, in order to verify signatures.

       This tool is used by bootmail(8) to sign messages, but could easily be used by others.

       rootsign  can  optionally  encrypt  the  message as well, by setting the recipient's gpg(1) key id in the
       RECIPIENT_KEYID variable in I/etc/bootmail/gpg.conf.

FILES

       /etc/bootmail/gpg.conf, /var/lib/rootsign/*.rsa.pub
