Build Instructions for sample SSL programs

Java programs

The Java programs have only been tested on Windows 2000 using the JDK1.4 Standard Edition as downloaded from Sun's web site. I've no reason to believe they won't work on other 1.4 implementations.

Note though that the programs depend on functionality introduced in 1.4, and while it may be possible to make them work using an earlier JDK with the JSSE classes that are separately available from Sun, this has not been tested.

Building the Java code is simple, use:

   > javac ExampleSSLClient.java
   > javac ExampleSSLServer.java

Neither program has any package identification, and neither requires any classes other than those that are included in the JFC. So after compiling them you'll just see some ".class" files turning up in your current directory.

C programs

For VMS, the environment I used was:

• OpenVMS Alpha V7.2-1
• Compaq C V6.2-003
• SSL$LIBSSL_SHR id "SSL 0.9.6" link date "22-JAN-2002 16:59:54.24"
• SSL$LIBCRYPTO_SHR id "CRYPTO 0.9.6" link date "22-JAN-2002 16:59:34.94" (I haven't tried building against the static libraries for SSL on VMS but have no reason to believe it wouldn't work)
• 64 bit pointers (i.e. "CC/POINTER=64"). I haven't tested with 32-bit pointers, but have no reason to believe it wouldn't work. I believe that if you use 32-bit pointers, you'll have to use the "_32" variants of the SSL shareables.
• SSL header files including "OPENSSLV.H" which says it is "OpenSSL 0.9.5a 1 Apr 2000". I have no reason to believe that the code won't work with later versions of the header files, but have not tested it.
• To build on VMS, I used defined SSL$LIBCRYPTO_SHR and SSL$LIBSSL_SHR to point to the shareable images, and then used the commands:

      $ define openssl {the directory containing openssl header files}
      $ cc/pointer=64 ExampleSSLClient.c
      $ cc/pointer=64 ExampleSSLServer.c
      $ link ExampleSSLClient,ssl.opt/opt
      $ link ExampleSSLServer,ssl.opt/opt
  

  where "ssl.opt" contains:

      ssl$libcrypto_shr/sha
      ssl$libssl_shr/sha
  

For Tru64 UNIX, the environment I used was:

• Tru64 UNIX V5.1 (Rev. 732)
• Compaq C V6.3-025
• OpenSSL 0.9.6c as downloaded from the OpenSSL web site. I have no reason to believe it won't work with later versions, but haven't tried it.
• To build on UNIX, I used commands like this:

    csh> cc -I/usr/users/hudson/openssl/include -c -o ExampleSSLClient.o ExampleSSLClient.c
    csh> cc -I/usr/users/hudson/openssl/include -c -o ExampleSSLServer.o ExampleSSLServer.c
    csh> cc -o ExampleSSLClient ExampleSSLClient.o /usr/users/hudson/openssl/libssl.a /usr/users/hudson/openssl/libcrypto.a
    csh> cc -o ExampleSSLServer ExampleSSLServer.o /usr/users/hudson/openssl/libssl.a /usr/users/hudson/openssl/libcrypto.a
