NAME

       getcert

SYNOPSIS

       getcert start-tracking [options]

DESCRIPTION

       Tells  certmonger  to  monitor  an  already-issued  certificate.   Optionally, when the certificate nears
       expiration, use an existing key pair (or to generate one if one is not already  found  in  the  specified
       location), to generate a signing request using the key pair and to submit them for signing to a CA.

SPECIFYING EXISTING REQUESTS

       -i NAME
              Modify the request which has this nickname.  If this option is not specified, and a tracking entry
              which  matches  the  key  and certificate storage options which are specified already exists, that
              entry will be modified.  Otherwise, a new tracking entry will be added.

KEY AND CERTIFICATE STORAGE OPTIONS

       -d DIR Use an NSS database in the specified directory for reading this certificate and, if possible,  the
              corresponding key.

       -n NAME
              Use  the  certificate  with  this  nickname,  and if a private key with the same nickname or which
              corresponds to the certificate is available, to use it, too.  Only valid with -d.

       -t TOKEN
              If the NSS database has more than one token available, use the token with this name for  accessing
              the certificate and key.  This argument only rarely needs to be specified.  Only valid with -d.

       -f FILE
              Read  the  certificate from this file.  For safety's sake, do not use the same file specified with
              the -k option.

       -k FILE
              Use the key stored in this file to generate a signing request for refreshing the certificate.   If
              no such file is found when needed, generate a new key pair and store them in the file.  Only valid
              with -f.

KEY ENCRYPTION OPTIONS

       -p FILE
              The  private  key  files  or databases are encrypted using the PIN stored in the named file as the
              passphrase.

       -P PIN The private key files or databases are encrypted  using  the  specified  PIN  as  the  passphrase.
              Because command-line arguments to running processes are trivially discoverable, use of this option
              is not recommended except for testing.

TRACKING OPTIONS

       -I NAME
              Assign  the  specified  nickname  to  this  task.  If this option is not specified, a name will be
              assigned automatically.

       -r     Attempt to obtain a new certificate from the CA when the expiration date of a  certificate  nears.
              This is the default setting.

       -R     Don't  attempt  to  obtain a new certificate from the CA when the expiration date of a certificate
              nears.  If this option is specified, an expired certificate will simply stay expired.

ENROLLMENT OPTIONS

       -c NAME
              Enroll with the specified CA rather than a possible default.  The name of the CA should correspond
              to one listed by getcert list-cas.  Only useful in combination with -r.

       -T NAME
              Request a certificate using the named profile, template, or certtype, from the specified CA.

SIGNING REQUEST OPTIONS

If and when certmonger attempts to obtain a new certificate to replace the one being monitored, the
values to be added to the signing request will be taken from the current certificate, unless preferred
values are set using one or more of -uU, -K, -E, and -D.

-u keyUsage
Add an extensionRequest for the specified keyUsage to the signing request. The keyUsage value is
expected to be one of these names:

digitalSignature

nonRepudiation

keyEncipherment

dataEncipherment

keyAgreement

keyCertSign

cRLSign

encipherOnly

decipherOnly

-U EKU Add an extensionRequest for the specified extendedKeyUsage to the signing request. The EKU value
is expected to be an object identifier (OID).

-K NAME
Add an extensionRequest for a subjectAltName, with the specified Kerberos principal name as its
value, to the signing request.

-E EMAIL
Add an extensionRequest for a subjectAltName, with the specified email address as its value, to
the signing request.

-D DNSNAME
Add an extensionRequest for a subjectAltName, with the specified DNS name as its value, to the
signing request. -A ADDRESS Add an extensionRequest for a subjectAltName, with the specified IP
address as its value, to the signing request.

-l FILE
Add an optional ChallengePassword value, read from the file, to the signing request. A
ChallengePassword is often required when the CA is accessed using SCEP.

-L PIN Add the argument value to the signing request as a ChallengePassword attribute. A
ChallengePassword is often required when the CA is accessed using SCEP.

OTHER OPTIONS

       -B COMMAND
              When ever the certificate or the CA's certificates are saved to the specified locations,  run  the
              specified command as the client user before saving the certificates.

       -C COMMAND
              When  ever  the certificate or the CA's certificates are saved to the specified locations, run the
              specified command as the client user after saving the certificates.

       -a DIR When ever the certificate is saved to the specified location, if root certificates for the CA  are
              available, save them to the specified NSS database.

       -F FILE
              When  ever the certificate is saved to the specified location, if root certificates for the CA are
              available, and when the local copies of the CA's root certificates are updated, save them  to  the
              specified file.

       -w     Wait for the certificate to become valid or to be reissued and saved, or for the attempt to obtain
              a new one to fail.

       -v     Be  verbose  about  errors.   Normally,  the  details of an error received from the daemon will be
              suppressed if the client can make a diagnostic suggestion.

NOTES

       Locations specified for key and certificate storage need  to  be  accessible  to  the  certmonger  daemon
       process.  When run as a system daemon on a system which uses a mandatory access control mechanism such as
       SELinux,  the  system  policy  must  ensure  that  the  daemon  is  allowed to access the locations where
       certificates and keys that it will manage will be stored (these locations are typically labeled as cert_t
       or an equivalent).  More SELinux-specific information can be found in the selinux.txt documentation  file
       for this package.
