# verify-proxy-tool(1)

tool to verify a certificate chain including proxies

## NAME

verify-proxy-tool - tool to verify a certificate chain including proxies

## SYNOPSIS

**verify-proxy-tool** \[**-h**\|**--help**\] \[**-d**\|**--debug**\] \[**-q**\|**--quiet**\] \[**-t**\|**--atnotbefore\]** \[**proxy**\]

## DESCRIPTION

This tool does a full chain check of a proxy, following the same logic as the **lcmaps\_verify\_proxy.mod** LCMAPS plugin. See for details the corresponding man page.

When no proxy filename is specified as last argument, the default proxy filename for the user is used, i.e. /tmp/x509up\_u\<UID\>.

## OPTIONS

- **-d, --debug**

  Show (debug) output, repeat this option to get more debugging output.

- **-q, --quiet**

  Show less output, only printing errors, not warnings.

- **-h, --help**

  Show short helptext

- **-t, --atnotbefore**

  Verify the proxy chain at (5 minutes after) the 'notBefore' time of the leaf proxy instead of at the current time.

## RETURN VALUES

- **0**

  verification and program succeeded

- **1**

  non-verification error, e.g. setup of parameters failed.

- **2**

  verification error, i.e. proxy is invalid.
