grid-proxy-init - Generate a new proxy certificate

SYNOPSIS


grid-proxy-init -help | -usage | -version

grid-proxy-init [OPTIONS]

DESCRIPTION


The grid-proxy-init program generates X.509 proxy certificates derived from the currently
available certificate files. By default, this command generates a <ulink
url="http://www.ietf.org/rfc/rfc3820.txt">RFC 3820</ulink> Proxy Certificate with a 1024
bit key, valid for 12 hours, in a file named /tmp/x509up_u’UID'. Command-line options and
environment variables can modify the format, strength, lifetime, and location of the
generated proxy certificate.

X.509 proxy certificates are short-lived certificates, signed usually by a user’s identity
certificate or another proxy certificate. The key associated with a proxy certificate is
unencrypted, so applications can authenticate using a proxy identity without providing a
pass phrase.

Proxy certificates provide a convenient alternative to constantly entering passwords, but
are also less secure than the user’s normal security credential. Therefore, they should
always be user-readable only (this is enforced by the GSI libraries), and should be
deleted after they are no longer needed.

This version of grid-proxy-init supports three different proxy formats: the old proxy
format used in early releases of the Globus Toolkit up to version 2.4.x, an IETF draft
version of X.509 Proxy Certificate profile used in Globus Toolkit 3.0.x and 3.2.x, and the
RFC 3820 profile used in Globus Toolkit Version 4.0.x and 4.2.x. By default, this version
of grid-proxy-init creates an RFC 3820 compliant proxy. To create a proxy compatible with
older versions of the Globus Toolkit, use the -old or -draft command-line options.

OPTIONS


The full set of command-line options to grid-proxy-init are:

-help, -usage
Display the command-line options to grid-proxy-init.

-version
Display the version number of the grid-proxy-init command.

-debug
Display information about the path to the certificate and key used to generate the
proxy certificate, the path to the trusted certificate directory, and verbose error
messages.

-q
Suppress all output from grid-proxy-init except for pass phrase prompts.

-verify
Perform certificate chain validity checks on the generated proxy.

-valid HOURS:MINUTES, -hours HOURS
Create a certificate that is valid for HOURS hours and MINUTES minutes. If not
specified, the default of twelve hours is used.

-cert CERTFILE, -key KEYFILE
Create a proxy certificate signed by the certificate located in CERTFILE using the key
located in KEYFILE. If not specified the default certificate and key will be used.
This overrides the values of environment variables described below.

-certdir CERTDIR
Search CERTDIR for trusted certificates if verifying the proxy certificate. If not
specified, the default trusted certificate search path is used. This overrides the
value of the X509_CERT_DIR environment variable.

-out PROXYPATH
Write the generated proxy certificate file to PROXYPATH instead of the default path of
/tmp/x509up_u’UID'.

-bits BITS
When creating the proxy certificate, use a BITS bit key instead of the default
1024-bit keys.

-policy POLICYFILE
Add the certificate policy data described in POLICYFILE as the ProxyCertInfo X.509
extension to the generated proxy certificate.

-pl POLICY-OID, -policy-language POLICY-OID
Set the policy language identifier of the policy data specified by the -policy
command-line option to the OID specified by the POLICY-OID string.

-path-length MAXIMUM
Set the maximum length of the chain of proxies that can be created by the generated
proxy to MAXIMUM. If not set, the default of an unlimited proxy chain length is used.

-pwstdin
Read the private key’s pass phrase from standard input instead of reading input from
the controlling tty. This is useful when scripting grid-proxy-init.

-limited
Create a limited proxy. Limited proxies are generally refused by process-creating
services, but may be used to authorize with other services.

-independent
Create an independent proxy. An independent proxy is not treated as an impersonation
proxy but as a separate identity for authorization purposes.

-draft
Create a IETF draft proxy instead of the default RFC 3280-compliant proxy. This type
of proxy uses a non-standard proxy policy identifier. This might be useful for
authenticating with older versions of the Globus Toolkit.

-old
Create a legacy proxy instead of the default RFC 3280-compliant proxy. This type of
proxy uses a non-standard method of indicating that the certificate is a proxy and
whether it is limited. This might be useful for authenticating with older versions of
the Globus Toolkit.

-rfc
Create an RFC 3820-compliant proxy certificate. This is the default for this version
of grid-proxy-init.

EXAMPLES


To create a proxy with the default lifetime and format, run the grid-proxy-init program
with no arguments. For example:

% grid-proxy-init
Your identity: /DC=org/DC=example/CN=Joe User
Enter GRID pass phrase for this identity: XXXXXXX
Creating proxy .................................. Done
Your proxy is valid until: Thu Mar 18 03:48:05 2010

To create a stronger proxy that lasts for only 8 hours, use the -hours and -bits
command-line options to grid-proxy-init. For example:

% grid-proxy-init -hours 8 -bits 4096
Your identity: /DC=org/DC=example/CN=Joe User
Enter GRID pass phrase for this identity: XXXXXXX
Creating proxy .................................. Done
Your proxy is valid until: Thu Mar 17 23:48:05 2010

ENVIRONMENT


The following environment variables affect the execution of grid-proxy-init:

X509_USER_CERT
Path to the certificate to use as issuer of the new proxy.

X509_USER_KEY
Path to the key to use to sign the new proxy.

X509_CERT_DIR
Path to the directory containing trusted certificates and signing policies.
