The following information was provided to us courtesy of the IBM
|
|
testing team, who tested the functionality of apache with mod_ssl
|
|
on SUSE LINUX Enterprise Server 9 for S/390 and zSeries.
|
|
|
|
It thus refers to testing only from a certain point, and the
|
|
z90crypt part is of course specific to S/390 and zSeries.
|
|
|
|
-------------------------------------------------------------------
|
|
Installation and Configuration of S/390 HW Crypto
|
|
on SUSE Linux Enterprise Server 9 for S/390 and zSeries:
|
|
|
|
1) Installation of the driver packages openCryptoki and libica
|
|
|
|
The driver packages are installed during base install in the
|
|
default selection. If you installed only minimal system or
|
|
deinstalled the packages, install them now. If the installation
|
|
source is accessible, you can do it with a single command:
|
|
|
|
31bit:
|
|
yast sw_single openCryptoki openCryptoki-32bit
|
|
|
|
64bit:
|
|
yast sw_single openCryptoki openCryptoki-32bit openCryptoki-64bit
|
|
|
|
This will automatically install the necessary libica packages as
|
|
well if they are not installed yet.
|
|
|
|
|
|
2) Loading the z90crypt driver:
|
|
|
|
systemctl start z90crypt to load z90crypt
|
|
|
|
systemctl stop z90crypt to unload z90crypt
|
|
|
|
this command will be available only after installation of the
|
|
crypto driver packages.
|
|
|
|
To load the driver automatically at every system boot, integrate it
|
|
with the other boot scripts issuing
|
|
|
|
systemctl enable z90crypt
|
|
|
|
|
|
3) Checking if the z90crypt hardware driver can be accessed
|
|
|
|
Run this command:
|
|
|
|
openssl speed rsa1024 -engine ibmca -elapsed
|
|
|
|
If you get 'can't use that engine', as the first line
|
|
of output of the command look for the successive line
|
|
and check:
|
|
- if running "rcz90crypt restart" gives no error message
|
|
- the output of command "dmesg" for error messages from the driver
|
|
- the hardware is indeed available to this instance
|
|
|
|
4) Installation and Setup of mod_ssl and apache
|
|
|
|
a) ensure that mod_ssl and apache are installed during base
|
|
install. If the installation source is accessible,
|
|
the command
|
|
|
|
yast sw_single mod_ssl
|
|
|
|
will install apache and mod_ssl if they are not installed yet.
|
|
|
|
b) to activate the apache ssl support do the following:
|
|
|
|
if you did not use yast to install the packages, you have
|
|
to run manually: SuSEconfig --module apache
|
|
|
|
edit /etc/sysconfig/apache:
|
|
change HTTPD_START_TIMEOUT=2 to 20
|
|
|
|
change HTTPD_SEC_MOD_SSL=no to yes
|
|
|
|
edit httpd.conf in /etc/httpd:
|
|
|
|
in section 2: check that the ServerName and ServerMail in
|
|
the ServerAdmin section is ok.
|
|
|
|
in section 3: set inside <VirtualHost_default_: 443> the
|
|
ServerName to host name
|
|
|
|
add on section <IfModule mod_ssl.c>: SSLCryptoDevice ibmca
|
|
|
|
run: SuSEconfig --module apache
|
|
|
|
5) Crypto configuration of apache/mod_ssl:
|
|
|
|
a) create a certificate (Snake Oil) for the TEST --- THIS
|
|
CERTIFICATE IS NOT SECURE FOR PRODUCTION USE! IT IS FOR
|
|
TESTING PURPOSES ONLY! GET A PROPER CERTIFICATE FROM A
|
|
CERTIFICATION AUTHORITY FOR PRODUCTION USE.
|
|
|
|
go to: cd /usr/share/doc/packages/mod_ssl
|
|
|
|
run: ./certificate.sh
|
|
|
|
see following questions will come up. Give shown answers
|
|
and use the pass phrase:
|
|
|
|
der3gbe:/usr/share/doc/packages/mod_ssl # ./certificate.sh

The generated X.509 CA certificate can contain either
|
|
RSA or DSA based ingredients. Select the one you want to use.

Using configuration from .mkcert.cfg
|
|
You are about to be asked to enter information that will be
|
|
incorporated
|
|
into your certificate request.
|
|
What you are about to enter is what is called a Distinguished
|
|
Name or a DN.
|
|
There are quite a few fields but you can leave some blank
|
|
For some fields there will be a default value,
|
|
If you enter '.', the field will be left blank.

STEP 4: Enrypting RSA private key with a pass phrase for
|
|
security [server.key]
|
|
The contents of the server.key file (the generated private key)
|
|
has to be
|
|
kept secret. So we strongly recommend you to encrypt the
|
|
server.key file
|
|
with a Triple-DES cipher and a Pass Phrase.
|
|
Encrypt the private key now? [Y/n]: Y
|
|
read RSA key
|
|
writing RSA key
|
|
Enter PEM pass phrase: <=== crypto
|
|
Verifying password - Enter PEM pass phrase: <=== crypto
|
|
Fine, you're using an encrypted RSA private key.
|
|
|
|
RESULT: Server Certification Files
|
|
|
|
o conf/ssl.key/server.key
|
|
|
|
The PEM-encoded RSA private key file which you
|
|
configure with the 'SSLCertificateKeyFile' directive
|
|
(automatically done when you install via APACI). KEEP
|
|
THIS FILE PRIVATE!
|
|
|
|
o conf/ssl.crt/server.crt
|
|
|
|
The PEM-encoded X.509 certificate file which you configure
|
|
with the 'SSLCertificateFile' directive (automatically done
|
|
when you install via APACI).
|
|
|
|
o conf/ssl.csr/server.csr
|
|
|
|
The PEM-encoded X.509 certificate signing request file
|
|
which you can send to an official Certificate Authority
|
|
(CA) in order to request a real server certificate
|
|
(signed by this CA instead of our demonstration-only
|
|
Snake Oil CA) which later can replace the
|
|
conf/ssl.crt/server.crt file.

6) Start Apache with SSL
|
|
|
|
a) start with pass phrase (Changes done to apache modul
|
|
described in item c)).
|
|
|
|
run: rcapache start
|
|
|
|
dev3fe01:~ # rcapache start
|
|
|
|
Starting httpd [ PERL PHP4 Python SSL ]Apache/1.3.26
|
|
mod_ssl/2.8.10 (Pass Phrase Dialog)
|
|
Some of your private key files are encrypted for security
|
|
reasons.
|
|
In order to read them you have to provide us with the pass
|
|
phrases.
|
|
|
|
Server dev3fe01.boeblingen.de.ibm.com:443 (RSA)
|
|
Enter pass phrase: crypto
|
|
|
|
Ok: Pass Phrase Dialog successful.
|
|
done
|
|
|
|
b) start without pass phrase when using apache without
|
|
ssl-support
|
|
|
|
remark: You need to change the apache modul (see
|
|
item c)). Set the HTTPD_SEC_MOD_SSL=no.
|
|
|
|
run: rcapache start
|
|
|
|
|
|
7) Check that ibmca is used and apache is working with http and https:
|
|
|
|
a) On a browser enter http://<server-host> or
|
|
https://<server-host>
|
|
b) with netstat or netstat -a on the apache server machine you
|
|
can see if https is used.
|
|
c) in the log /var/log/httpd/ssl_engine_log you can see if the
|
|
ibmca engine is started or not.
|
|
d) during siege test you can see with cat /proc/driver/z90crypt
|
|
if and what crypto HW is used
|
|
e) you can check a http connection with telnet <server-host>
|
|
http. Then enter
|
|
get / http/1.0
|
|
and you should get back some stuff after pressing enter
|
|
twice.
|
|
|
|
f) You can check if openssl works with the ibmca engine
|
|
|
|
a) Therefore you must create certificates:
|
|
cd /usr/share/ssl/misc
|
|
run: ./CA.sh -newcert
|
|
|
|
dev3fe01:/usr/share/ssl/misc # ./CA.sh -newcert
|
|

|
|
You are about to be asked to enter information that will be
|
|
incorporated
|
|
into your certificate request.
|
|
What you are about to enter is what is called a
|
|
Distinguished Name or a DN.
|
|
There are quite a few fields but you can leave some blank
|
|
For some fields there will be a default value,
|
|
If you enter '.', the field will be left blank.

|
|
Certificate (and private key) is in newreq.pem
|

run: ./CA.sh -newca

b) Use openssl as a Web-browser and use https connection:
|
|
openssl s_client \
|
|
-connect <ip-addr of webserver>:443 -state -debug
|
|
|
|
The machine were you start the client is working as
|
|
your 'browser' connecting to the webserver. You can
|
|
start commands from the client like get / http/1.0 .
|
|
|
|
c) Use openssl as a Web-server and use https connection:
|
|
openssl s_server \
|
|
-accept 443 -www -engine ibmca -cert newreq.pem
|
|
|
|
The machine is working like a small webserver with full
|
|
openssl functionality. You can start your browser to
|
|
this machine and a lot of info will be sent.
|
|
|
|
dev3fe01:/usr/share/ssl/misc # openssl s_server -accept 443
|
|
-www -cert newreq.pem -engine ibmca
|
|
engine "ibmca" set.
|
|
Using default temp DH parameters
|
|
Enter PEM pass phrase: <== geheim
|
|
ACCEPT
