OpenSSL A.00.09.07m.049, A.00.09.07m.050, and A.00.09.08k.003 Release Notes

Table Of Contents

Example 1-1 If you are running OpenSSL A.00.09.07m.049 on HP-UX 11i v1

# what /usr/bin/openssl

/usr/bin/openssl:

$OpenSSL A.00.09.07m.049 $

Example 1-2 If you are running OpenSSL A.00.09.08k.003 on HP-UX 11i v3

# what /usr/bin/openssl

/usr/bin/openssl:

$OpenSSL A.00.09.08k.003 $

18 How do I find out whether I am running Internet Express OpenSSL, OpenSSL A.00.09.07m,

OpenSSL A.00.09.08k or the Open Source version of OpenSSL?

Run the what command to display the OpenSSL bundle installed on your system. Following

are some examples:

Example 1-3 When an old version of OpenSSL from Internet Express is installed on the system

# what /usr/bin/openssl

OpenSSL A.02.00-0.9.7c

Example 1-4 When OpenSSL A.00.09.07m.050 is installed on an HP-UX 11i v2 operating

system

# what /usr/bin/openssl

/usr/bin/openssl:

$OpenSSL A.00.09.07m.050 $

Example 1-5 You do not have an HP-UX depot installed but have downloaded the source code

and built the product yourself

# what /usr/bin/openssl

The output of the what command depends on what you defined for the $what string in the

source code before you built the product.

19 A lot of information is available for OpenSSL-enabler products, such as Stunnel. How is

Stunnel different from my OpenSSL A.00.09.07m or A.00.09.08k installation?

Consider a client-server application sending and receiving unencrypted data over the network.

The following methods describe how to use OpenSSL technology to encrypt client/server

communication:

• To implement secure communication, you can modify client and server code using

OpenSSL functions. This method gives you the highest degree of flexibility and control

regarding the features and how you implement them.

• You can set up an Stunnel-based environment in which data from the client application

is sent to an Stunnel client instead of to the server. The Stunnel client encrypts the data

using OpenSSL technology and sends encrypted data to the Stunnel server. The Stunnel

server decrypts the data and sends the original data to the target server application. The

same process is followed when data is sent from the server to the client application. This
