NAME

       gvm-manage-certs - manage certificate infrastructure for a GVM installation

SYNOPSIS

       gvm-manage-certs [OPTION]...

DESCRIPTION

       gvm-manage-certs  manages  the  certificate  infrastructure  for  a GVM installation.  The
       certificate infrastructure enables GVM daemons to communicate in a secure  manner  and  is
       used  for authentication and authorization before establishing TLS connections between the
       daemons.

       The GVM certificate infrastructure consists of  a  certificate  authority  (CA)  which  is
       trusted by all GVM daemons.  This CA is then used to sign certificates used by the various
       daemons.  The certificates can be divided into two use cases:

       •  Server certificates, primarily used for authentication

       •  Client certificates, primarily used for authorization

       gvm-manage-certs can perform an automatic creation of a default certificate infrastructure
       for  a  standard  GVM  installation.   It  can  also verify an existing infrastructure and
       perform various certificate  related  tasks  to  support  the  setup  of  a  more  complex
       infrastructure.

OPTIONS

   Certificate infrastructure management
       -a     Automatically set up default infrastructure for GVM

       -V     Verify existing GVM certificate infrastructure

       -C     Create a certificate authority (CA)

       -R     Create a certificate request for a CA

       -r     Create a certificate request for a CA and sign it

       -C     Create a certificate authority (CA)

       -I     Install a CA certificate

       -c     Create a certificate request and sign it

       -i     Install a certificate

       -S     Sign a certificate request

       -f     Force overwriting of existing files

   Certificate options
       -E     Create a server certificate.  This sets the appropriate key usage constraints for a
              server certificate.

       -L     Create a client certificate.  This sets the appropriate key usage constraints for a
              client certificate.

       -A     Skip CA generation in automatic mode.  This automatically (re-)generates server and
              client certificates, but keeps the CA certificate.

   Configuration
       -e file Read configuration from file (see below for configuration details)

   Output control
       -d     Print debug output

       -v     Print verbose messages

       -q     Be quiet, only print error messages

   Other options
       -h     Print help

EXIT STATUS

       0      The requested operation was successfully performed.

       1      An error occurred, the requested operation could not be performed.

ENVIRONMENT

       All certificate generation options can be set either through  the  configuration  file  or
       through environment variables like the following:

       GVM_CERTIFICATE_LIFETIME
              Days until the certificate will expire

       GVM_CERTIFICATE_HOSTNAME
              Name to use for the certificate

       GVM_CERTIFICATE_SIGNALG
              Hash algorithm to use for signing

       GVM_CERTIFICATE_KEYSIZE
              Size in bits of the generated key

       GVM_CERTIFICATE_SECPARAM
              GnuTLS security level [low|medium|high|ultra]

       GVM_CERT_DIR
              Directory where keys and certificates are stored before installation

       GVM_CERT_PREFIX
              Prefix for certificate filename (e.g. "server")

       For a complete list of options, please refer to the example configuration file included in
       the documentation.
