Stephan Kulow 053908a9ac Accepting request 484290 from openSUSE:Factory:zSystems
Major rework of package to conform to shared library policy, including being renamed from libica2 to libica.
Additional bugfixes from previous version.
Please also make me the maintainer of the package.

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:
rcz90crypt start to load z90crypt
rcz90crypt stop 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
insserv 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

Generating test certificate signed by Snake Oil CA [TEST]
WARNING: Do not use this for real-life/production systems
STEP 0: Decide the signature algorithm used for certificate
The generated X.509 CA certificate can contain either
RSA or DSA based ingredients. Select the one you want to use.
Signature Algorithm ((R)SA or (D)SA) [R]:R

STEP 2: Generating X.509 certificate signing request
[server.csr]
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.

1. Country Name (2 letter code) [XY]:DE
2. State or Province Name (full name) [Snake Desert]:

3. Locality Name (eg, city) [Snake Town]:
<enter>
4. Organization Name (eg, company) [Snake Oil, Ltd]:

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
Using configuration from /etc/ssl/openssl.cnf

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
