     CREATESIGNERKEY(8)                             CREATESIGNERKEY(8)

          createsignerkey - create signer key on authentication server

          auth/createsignerkey [ -a alg ] [ -f keyfile ] [ -e expiry ]
          [ -b bitsize ] name

          Createsignerkey creates public and private keys that are
          used by a server acting as `signer' to generate certificates
          for users.  Name appears as signer in each certificate.  The
          expiry date has the form ddmmyyyy, is converted to seconds
          since the epoch (see daytime(2)) and stored in the keyfile;
          by default the server's certificate never expires.

          The key will be bitsize long (default: 512 bits) with a min-
          imum of 32 bits and a maximum of 4096 bits.  Keyfile is the
          file in which the server stores its keys; the default is
          /keydb/signerkey, and many authentication programs such as
          logind(8) by default expect to find their server key there.
          Creating a signer's default key afresh typically invalidates
          all certificates previously issued by that signer, because
          their signatures will not verify.  The mode of the keyfile
          should be set to be readable only by the user running those

          The -a option specifies the signature algorithm.  Currently
          alg can be either elgamal or rsa.  RSA keys are now used by



          security-auth(2), keyring-gensk(2), logind(8), signer(8)
