This is a port of OpenSSL 1.0.1g to MSDOS/DJGPP.
The OpenSSL Project is an Open Source toolkit implementing the Secure Sockets
Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as
a full-strength general purpose cryptography library. OpenSSL is based on
the excellent SSLeay library developed from Eric A. Young and Tim J. Hudson.
The OpenSSL toolkit is licensed under a dual-license (the OpenSSL license
plus the SSLeay license) situation, which basically means that you are free
to get and use it for commercial and non-commercial purposes as long as you
fulfill the conditions of both licenses.
There are no DJGPP specific changes compared with the last port.
DJGPP specific changes.
=======================
Fortunately, OpenSSL supports DJGPP out-of-the-box so there is no need to
adjust the source code itself. Neither less there are assumptions made about
the file system used and its capabilities that require some changes in the
perl configuration scripts and in the way source package is unzipped.
- all new DJGPP specific files are store in the /djgpp directory.
- to install, configure and compile the sources LFN support is required.
- all links (linked files) in the archive have been removed. Depending on
if djtar or tar is used and depending on if they are from DJGPP 2.03 or
2.04 all these tar programs create different kind of files to represent
those links and this breaks either the configuration step or later the
building step.
- the /djgpp directory contains unpack.sh. This small shell script uses
djtar to create a file list of the archive, identifies the links, extract
the sources using djtar and removes all links. Of course, if you download
the DJGPP port all this has already been done.
- as usual the /djgpp directory contains also the diffs file. It shows how
I have changed some of the perl scripts used during the configuration and
building steps to check for the OS used and to copy the files instead of
trying to create links even if this is possible.
- the binaries, headers and libraries will be installed in the corresponding
directories of the DJGPP installation tree. All documentation will be
installed in /dev/env/DJDIR/share/ssl/man. This means that you will have
to adjust your MANPATH in djgpp.env if you want that the man program finds
these new manpages.
- to be able to configure and compile this port, the DJGPP port of perl must
be installed. openssl uses a mix of perl scripts and Makefiles to configure
and compile the sources. I have used perl588b but the previous one may work
as well but I have never tested this.
- the library has been compiled using -march=i386 -mtune=i586 to generate
i386 compatible code. These are the same flags that are used to build the
C library of DJGPP from the CVS repository. These flags may not work with
very old compilers and may have to been adjusted accordingly.
- to be able to configure and compile this port, the DJGPP port of WATT32
must be installed. It can be downloaded as:
ftp://ftp.delorie.com/pub/djgpp/current/v2tk/wat3222br3.zip
or:
ftp://ftp.delorie.com/pub/djgpp/beta/v2tk/wat3222br3.zip
As usual the version from the /current directory is for the use with
djdev203 and the one from the /beta directory is for the use with djdev204.
After having installed the port make sure that the WATT_ROOT environment
variable points to the directory where the headers and the library reside.
This is:
set WATT_ROOT=/dev/env/DJDIR/net/watt
Due to the dependency of WATT-32 and the required value of the WATT_ROOT
environment variable, the source package is not configured at all. You
have to install WATT-32 first and then you can configure and build openssl
as described in the original INSTALL.DJGPP file.
Please do NOT use any previous DJGPP ports of WATT-32.
- the port has been configured and compiled to support for zlib compression.
The zlib port used is
ftp://ftp.delorie.com/pub/djgpp/current/v2tk/zlib128b.zip
or:
ftp://ftp.delorie.com/pub/djgpp/beta/v2tk/zlib128b.zip
but any other version of the port may work as well. As usual the version
from the /current directory is for the use with djdev203 and the one from
the /beta directory is for the use with djdev204.
- the test suite passes for both djdev203 and djdev204 except for the last
test that requires some certificate that needs to be requested. For some
test, it is also required that the port of GNU bc is installed.
- the binary package of openssl ist not completely SFN clean. But this
concerns the manpages only. Neither the libraries nor the headers are
affected. I do not have the time to invent SFN clean names for hundreds
of manpages which names may change and become useless with the next
openssl update. Of course, the headers and libraries are 8.3 clean and
the use of the libraries do not require LFN support at all.
- as any cryptographic software, openssl needs a source of unpredictable
data to work correctly. Many open source operating systems provide a
"randomness device" (/dev/urandom or /dev/random) that serves this
purpose. As of version 0.9.7f of openssl the DJGPP port checks upon
/dev/urandom$ for a 3rd party "randomness" DOS driver. One such driver,
NOISE.SYS, can be obtained from "http://www.rahul.net/dkaufman/index.html"
as:
<http://www.rahul.net/dkaufman/noise063a2.zip>
Please read the instructions carefully. This driver works on DOS and may
be on some versions of Windows but it does not work for all versions of
Windows. For XP it does not work and I have found no replacement. This
means that for WinXP and probably for Win2K there is there is no "randomness"
support for openssl available.
- most but not all programs of the /examples directory can be successfully
compiled but they may not work. I have no intention to fix them, neither
less they may serve as example how to use the library and how to compile
and link your application with this library together with the WAT32 library
and the zlib library.
- the binaries have been build on WinXP using djdev203 or djdev204, gcc472b
and bnu224b.
Configuring, compiling and running the test suite takes around 01:30 h.
For further information about OpenSSL please read the man pages,
various README files and NEWS file. Also visit the home page of openssl.
Please note that I am not an user of openssl. I have only ported it because
I needed it to create another port. This means that I am not able to answer
openssl specific questions.
The port has been compiled using stock djdev203 (patchlevel 2) and consists
of two packages that can be downloaded from ftp.delorie.com and mirrors as
