PROGRAM:
NAME
getcert
SYNOPSIS
getcert request [options]
DESCRIPTION
Tells certmonger to 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.
KEY AND CERTIFICATE STORAGE OPTIONS
-d DIR Use an NSS database in the specified directory for storing this certificate and
key.
-n NAME
Use the key with this nickname to generate the signing request. If no such key is
found, generate one. Give the enrolled certificate this nickname, too. Only valid
with -d.
-t TOKEN
If the NSS database has more than one token available, use the token with this name
for storing and accessing the certificate and key. This argument only rarely needs
to be specified. Only valid with -d.
-f FILE
Store the issued certificate in 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 the signing request. If no such file
is found, generate a new key pair and store them in the file. Only valid with -f.
KEY ENCRYPTION OPTIONS
-p FILE
Encrypt private key files or databases using the PIN stored in the named file as
the passphrase.
-P PIN Encrypt private key files or databases 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.
KEY GENERATION OPTIONS
-G TYPE
In case a new key pair needs to be generated, this option specifies the type of the
keys to be generated. If not specified, a reasonable default (currently RSA) will
be used.
-g BITS
In case a new key pair needs to be generated, this option specifies the size of the
key. If not specified, a reasonable default (currently 2048 bits) will be used.
TRACKING OPTIONS
-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.
-I NAME
Assign the specified nickname to this task. If this option is not specified, a
name will be assigned automatically.
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.
-T NAME
Request a certificate using the named profile, template, or certtype, from the
specified CA.
SIGNING REQUEST OPTIONS
If none of -N, -U, -K, -E, and -D are specified, a default group of settings will be used
to request an SSL server certificate for the current host, with the host Kerberos service
as an additional name.
-N NAME
Set the subject name to include in the signing request. The default used is
CN=hostname, where hostname is the local hostname.
-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), but some specific names
are also recognized. These are some names and their associated OID values:
id-kp-serverAuth 1.3.6.1.5.5.7.3.1
id-kp-clientAuth 1.3.6.1.5.5.7.3.2
id-kp-codeSigning 1.3.6.1.5.5.7.3.3
id-kp-emailProtection 1.3.6.1.5.5.7.3.4
id-kp-timeStamping 1.3.6.1.5.5.7.3.8
id-kp-OCSPSigning 1.3.6.1.5.5.7.3.9
id-pkinit-KPClientAuth 1.3.6.1.5.2.3.4
id-pkinit-KPKdc 1.3.6.1.5.2.3.5
id-ms-kp-sc-logon 1.3.6.1.4.1.311.20.2.2
-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 be issued and saved, or for the attempt to obtain 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.
