HAProxy OCSP Stapling Updater - $VERSION
|
||
|
|
Copyright (c) 2015 Pier Carlo Chiodi - http://www.pierky.com
|
||
|
|
|
||
|
|
https://github.com/pierky/haproxy-ocsp-stapling-updater
|
||
|
|
|
||
|
|
Usage:
|
||
|
|
$PROGNAME [options] --cert crt_full_path
|
||
|
|
|
||
|
|
This script extracts and queries the OCSP server present in a
|
||
|
|
certificate to obtain its revocation status, then updates HAProxy by
|
||
|
|
writing the '.issuer' and the '.ocsp' files and by sending it the
|
||
|
|
'set ssl ocsp-response' command through the local UNIX admin socket.
|
||
|
|
|
||
|
|
The crt_full_path argument is the full path to the certificate bundle
|
||
|
|
used in haproxy 'crt' setting. End-entity (EE) certificate plus any
|
||
|
|
intermediate CA certificates must be concatenated there.
|
||
|
|
An OCSP query is sent to the OCSP server given on the command line
|
||
|
|
(--ocsp-url and --ocsp-host argument); if these arguments are missing,
|
||
|
|
URL and Host header values are automatically extracted from the
|
||
|
|
certificate.
|
||
|
|
If the '.issuer' file already exists it's used to build the OCSP
|
||
|
|
request, otherwise the chain is extracted from crt_full_path and used
|
||
|
|
to identify the issuer.
|
||
|
|
Finally, it writes the related '.issuer' and .'ocsp' files and updates
|
||
|
|
haproxy, using 'socat' and the local UNIX socket (--socket argument,
|
||
|
|
default $HAPROXY_ADMIN_SOCKET_DEFAULT).
|
||
|
|
|
||
|
|
Exit codes:
|
||
|
|
0 OK
|
||
|
|
1 openssl certificates handling error
|
||
|
|
2 OCSP server URL not found
|
||
|
|
3 string parsing / PEM manipulation error
|
||
|
|
4 OCSP error
|
||
|
|
5 haproxy management error
|
||
|
|
9 program error (wrong arguments, missing dependencies)
|
||
|
|
|
||
|
|
Options:
|
||
|
|
|
||
|
|
-d, --debug : don't do anything, print debug messages only.
|
||
|
|
|
||
|
|
--keep-temp : keep temporary directory after exiting (for
|
||
|
|
debug purposes).
|
||
|
|
|
||
|
|
-g, --good-only : do not update haproxy if OCSP response
|
||
|
|
certificate status value is not 'good'.
|
||
|
|
|
||
|
|
-l, --syslog priority : log errors to syslog system log module.
|
||
|
|
The priority may be specified numerically
|
||
|
|
or as a facility.level pair (e.g.
|
||
|
|
local7.error).
|
||
|
|
|
||
|
|
--ocsp-url url : OCSP server URL; use this instead of the
|
||
|
|
one in the EE certificate.
|
||
|
|
|
||
|
|
--ocsp-host host : OCSP server hostname to be used in the
|
||
|
|
'Host:' header; use this instead of the one
|
||
|
|
extracted from the OCSP server URL.
|
||
|
|
|
||
|
|
--partial-chain : Allow partial certificate chain if at least one certificate
|
||
|
|
is in trusted store. Useful when validating an intermediate
|
||
|
|
certificate without the root CA.
|
||
|
|
|
||
|
|
-s, --socket file : haproxy admin socket. If omitted,
|
||
|
|
$HAPROXY_ADMIN_SOCKET_DEFAULT is used by default.
|
||
|
|
This script is distributed with only one
|
||
|
|
method to update haproxy: using 'socat'
|
||
|
|
with a local admin-level UNIX socket.
|
||
|
|
Feel free to implement other mechanisms as
|
||
|
|
needed! The right section in the code is
|
||
|
|
\"UPDATE HAPROXY\", at the end of the script.
|
||
|
|
|
||
|
|
-v, --VAfile file : same as the openssl ocsp -VAfile option
|
||
|
|
with 'file' as argument. For more details:
|
||
|
|
'man ocsp'.
|
||
|
|
If file = \"-\" then the chain extracted
|
||
|
|
from the certificate's bundle (or .issuer
|
||
|
|
file) is used (useful for OCSP responses
|
||
|
|
that don't include the signer certificate).
|
||
|
|
|
||
|
|
--noverify : Do not verify OCSP response.
|
||
|
|
|
||
|
|
-S, --skip-update : Do not notify haproxy of the new OCSP response.
|
||
|
|
|
||
|
|
-h, --help : this help."
