Openssl Binary Distribution

[Desiree Friede]

Somepeople have offered to provide OpenSSL binary distributions for selected operating systems. The condition to get a link here is that the link is stable and can provide continued support for OpenSSL for a while.

Note: many Linux distributions come with pre-compiled OpenSSL packages. Those are already well-known among the users of said distributions, and will therefore not be mentioned here. If you are such a user, we ask you to get in touch with your distributor first. This service is primarily for operating systems where there are no pre-compiled OpenSSL packages.

There are binary distributions for Windows here, but I do not understand what does the character at the end of the version stands for (packages named like: Win32 OpenSSL v1.0.1b, Win32 OpenSSL v1.0.0i, ...).

After the release of OpenSSL 1.0.0 the versioning scheme changed. Letter releases (e.g. 1.0.1a) can only contain bug and security fixes and no new features. Minor releases change the last number (e.g. 1.0.2) and can contain new features that retain binary compatibility. Changes to the middle number are considered major releases and neither source nor binary compatibility is guaranteed.

However, the user skill level can vary a lot. Even just selecting a dialog to choose the directory where openssl is placed may be too hard for some, but I will have to solve that by either auto detection or good help/manual.

The standard location selected by OpenSSL on Unix and Unix-like operating systems is /usr/local/ssl. Header files are located in /usr/local/ssl/include, and library files are located in /usr/local/ssl/lib. Also see the INSTALL file and Compilation and Installation on the OpenSSL wiki.

For OpenSSL, the library is not Universal Binary safe, and its technically not feasible to build with multiple architectures. For the first item, not Universal Binary safe, that's because each configuration of OpenSSL produces a unique . For the second item, technically not feasible, you can't specify -arch i386 -arch x86_64 because it causes a compile failure due to the recipe to build the static archives.

Both can be worked around, but I'm not aware of a reference on the subject. I work closely with the libraries, so I happen to know about the problems and the fixes. I was just talking to some of the OpenSSL devs about creating a wiki page on Universal Binaries for Apple platforms.

The way to do such universal binary is to compile for each archtitecture separately. Then you can merge the libray files with the lipo tool into one.The header files which are different you can rename these files.

You should upgrade pip and attempt to install cryptography againbefore following the instructions to compile it below. Most Linuxplatforms will receive a binary wheel and require no compiler if you havean updated pip!

For RHEL and CentOS you must be on version 8.8 or newer for the commandbelow to install a sufficiently new Rust. If your Rust is less than 1.65.0please see the Rust installation instructionsfor information about installing a newer Rust.

Cryptography ships statically-linked wheels for macOS, Windows, and Linux (viamanylinux and musllinux). This allows compatible environments to usethe most recent OpenSSL, regardless of what is shipped by default on thoseplatforms.

If you are using a platform not covered by our wheels, you can build your ownstatically-linked wheels that will work on your own systems. This will allowyou to continue to use relatively old Linux distributions (such as LTSreleases), while making sure you have the most recent OpenSSL available toyour Python programs.

To do so, you should find yourself a machine that is as similar as possible toyour target environment (e.g. your production environment): for example, spinup a new cloud server running your target Linux distribution. On this machine,install the Cryptography dependencies as mentioned in Building cryptography on Linux.Please also make sure you have virtualenv installed: this should beavailable from your system package manager.

You will also need to have Rust installed andavailable, which can be obtained from Homebrew,MacPorts, or directly from the Rust website. If you are linking against auniversal2 archive of OpenSSL, the minimum supported Rust version is1.66.0.

Building cryptography requires having a working Rust toolchain. The currentminimum supported Rust version is 1.65.0. This is newer than the Rust somepackage managers ship, so users may need to install with theinstructions below.

Rust is only required when building cryptography, meaning that you mayinstall it for the duration of your pip install command and then remove itfrom a system. A Rust toolchain is not required to use cryptography. Indeployments such as docker, you may use a multi-stage Dockerfile whereyou install Rust during the build phase but do not install it in the runtimeimage. This is the same as the C compiler toolchain which is also required tobuild cryptography, but not afterwards.

The official source of OpenSSL software is the OpenSSL website. One can download OpenSSL source codes archives and compile them for a given platform. The compilation work can sometimes be quite tedious and may require a specific knowledge or tools, especially for exotic platforms.

We, at TeskaLabs, set up this page because we frequently compile OpenSSL for various platforms for our internal purposes and this may save some time to other developers. Binary distribution archives available on this page contains a statically linked OpenSSL libraries and header files. There are no other files (such as binaries like ./bin/openssl) included in this distribution. Developers can directly use them in their projects and save a bit of time.

At that time I lived in Prague for a short time, which is not a very friendly place to live, but it allowed me to go to the office almost every day. A bigger surprise awaited Vlaďka and Aleš when I told them that I was going to move to a house almost eighty kilometres from the office and that I would need to be mainly at the home office.

To show Apple a flaw in their environment, a team of University researchers created a malware app and uploaded it to the App Store. This malware can steal passwords from installed apps, email clients, and Google's Chrome web browser. By exploiting this flaw, hackers can bypass the App Store security check using this hacking app.

The Apache HTTP Server Project itself does not provide binary releases of software, only source code. Individual committers may provide binary packages as a convenience, but it is not a release deliverable.

TCP/IP must be correctly installed, configured and running in order to install and use Apache on Windows. If you use dial-up networking exclusively, you may need to be connected to the internet for Apache to correctly determine that TCP/IP is installed.

We suggest disabling the "Quality of Service" (or QoS) network driver from Microsoft if you primarily use the machine as an Apache Server, as Apache does not support the QoS extensions to the WinSock API.

Most Firewall programs, Web Spam filters and other TCP/IP driver-based products (including spyware!) do not correctly implement the entire WinSock API. The shortcuts taken by the developers of such products cause Apache to fail. If you insist on leaving such programs installed, and have problems with your Apache installation, consider the suggestion below.

If you encounter problems running Apache 2 under Windows, such as corrupted or incomplete file downloads, unexplained error messages, or a conflict with a software firewall, please place the following three directives in your httpd.conf configuration file to see if they eliminate the problems:

The general problem is that many people install various add-ons to windows (such as software firewalls, virus checkers, etc) that break some of the advanced functionality that Apache uses to speed the sending of files. The above directives turn off the advanced functionality and make Apache fall back to more basic (but slower) techniques. This resolves most, but not all of the potential problems. If you continue to experience problems, be certain that there is no spyware installed on the box, which exhibits exactly the same sorts of flaws (often more obviously).

The Apache User Support Mailing List and the comp.infosystems.www.servers.ms-windows newsgroup both provide peer to peer support. Pose your question or problem on only one forum at a time. If you do not follow these guidelines, your questions and pleas for assistance will likely go unanswered. To learn how to get questions answered effectively, you might want to read How to Ask Questions the Smart Way written by Eric S. Raymond and Rick Moen - which is a very good primer for end users to learn to pose effective questions to their fellow users and the project's developers. (NOTE they will only help you learn to ask questions, Eric and Rick do not provide you help with Apache HTTP Server!)
