DESCRIPTION
       The lprng_certs program is used to manage SSL certificates for the
       LPRng software.  There SSL certificate structure consists of a
       hierarchy of certificates.  The LPRng software assumes that the
       following types of certificates will be used:

       CA or root
              A top level or self-signed certificate.

       signing
              A certificate that can be used to sign other certificates.  This
              is signed by the root CA or another signing certificate.

       user   A certificate used by a user to identify themselves to the lpd
              server.

       server A certificate used by the lpd server to identify themselves to
              the user or other lpd servers.

Signing Certificates
       All of the signing certificates, including the root certificate (root
       CA), /etc/lpd/ssl.ca/ca.crt, are in the same directory as the root CA
       file.  Alternately, all of the signing certs can be concatenated and
       put into a single file, which by convention is assumed to have the same
       name as the root CA file, /etc/lpd/ssl.ca/ca.crt.  The ssl_ca_file,
       ssl_ca_path, and ssl_ca_key printcap and configuration options can be
       used to specify the locations of the root CA files, a directory
       containing the signing certificate files, and the private key file for
       the root CA file respectively.

       The root certificate (root CA file) /etc/lpd/ssl.ca/ca.crt has a
       private key file /etc/lpd/ssl.ca/ca.key as well.  By convention, the
       private keys for the other signing certificate files are stored in the
       certificate file.

       The OpenSSL software requires that this directory also contain a set of
       hash files which are, in effect, links to these files.

       By default, all signing certificates are assumed to be in the same
       directory as the root certificate.

Server Certificates
       The certificate used by the lpd server are kept in another directory.
       These files do not need to have hash links to them.  By convention, the
       private keys for these certificate files are stored in the certificate
       file.  The server certificate file is specified by the ssl_server_cert
       and has the default value /etc/lpd/ssl.server/server.crt.  This file
       contains the cert and private key.  The server certificate password
       file is specified by the ssl_server_password option with the default
       value @SSL_SERVER_PASSWORD@ and contains the password used to decrypt
       the servers private key and use it for authentication.  This key file
       should be read only by the lpd server.

User Certificates
       The certificates used by users are kept in a separate directory in the
       users home directory.  By convention, the private keys for these
       certificate files are stored in the certificate file.

       The user certificate file is specified by the LPR_SSL_FILE environment
       variable, otherwise the ${HOME}/.lpr/client.crt is used.  The password
       is taken from the file specified by the LPR_SSL_PASSWORD environment
       variable, otherwise the ${HOME}/.lpr/client.pwd file is read.

USING LPRNG_CERTS
       The organization of the SSL certificates used by LPRng is similar to
       that used by other programs such as the Apache mod_ssl support.  The
       lprng_certs program is used to create the directory structure, create
       certificates for the root CA, signing, user and servers.  In order to
       make managment simple, the following support is provided.

lprng_certs init
       This command creates the directories used by the lpd server.  It is
       useful when setting up a new lpd server.

lprng_certs newca
       This command creates a self-signed certificate, suitable for use as a
       root CA certificate.  It also sets up a set of default values for other
       certificate creation.

lprng_certs defaults
       This command is used to modify the set of default values.

       The default values are listed and should be self-explanatory, except
       for the value of the signer certificate.  By default, the root CA can
       be used to sign certificates.  However, a signing certificate can be
       used as well.  This allows delegation of signing authority without
       compromising the security of the root CA.

lprng_certs gen
       This is used to generate a user, server, or signing certificate.

lprng_certs index
       This is used to create the indexes for the signing certificates.

lprng_certs verify [cert]
       This checks the certificate file using the Openssl openssl verify
       command.

lprng_certs encrypt keyfile
       This removes all key information from the key file, reencrypts the key
       information, and the puts the encrypted key information in the file.

LPRng OPTIONS
       Option                   Purpose
       ssl_ca_path              directory holding the SSL signing certs
       ssl_ca_file              file holding the root CA or all SSL signing certs
       ssl_server_cert          cert file for the server
       ssl_server_password      file containing password for server server
       ${HOME}/.lpr/client.crt  client certificate file
       ${HOME}/.lpr/client.pwd  client certificate private key password

ENVIRONMENT VARIABLES
       LPR_SSL_FILE             client certificate file
       LPR_SSL_PASSWORD         client certificate private key password


EXIT STATUS
       The following exit values are returned:

       zero (0)       Successful completion.

       non-zero (!=0) An error occurred.
