Download OpenSSL for Mac - Cryptography library and toolkit that enables developers to work with the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. For an overview of some of the key concepts in OpenSSL 3.0 see the libcrypto manual page. Information and notes about migrating existing applications to OpenSSL 3.0 are available in the OpenSSL 3.0 Migration Guide. The OpenSSL FIPS Object Module (FOM) 2.0 is also available for download.

Installing OpenSSL can be tricky, and there are a few different ways to do this. To simplify your life, I have listed the method for each OS that I believe is the most straightforward.

Installing OpenSSL on Windows

This tutorial is mostly for Windows 10 users, since OpenSSL does not ship with Windows 10 by default.

OpenSSL can be installed with Chocolatey, which can be easily deployed in an organization or installed for a single user. It is also be a great tool for patch management.

Once Chocolatey has been installed, run the following command line:

Installing OpenSSL on Linux

Arch Linux

By default, OpenSSL is already included in Arch Linux. If this is not the case with your instance, then run the following command line:

CentOS / Red Hat

By default, OpenSSL is already included in CentOS. If this is not the case with your instance, then run the following command line:

Ubuntu

By default, OpenSSL is already included in Ubuntu. If this is not the case with your instance, then run the following command line:

Installing OpenSSL on macOS

By default, OpenSSL is already installed in macOS. However, your version may be outdated. If so, then you can install the latest version with Homebrew. After installing Homebrew, simply run the following command line:

Advanced: Self Compile

Some people do not trust the pre-compiled binaries available on the package sources listed above. If you feel this way, then OpenSSL can be compiled from sources by following the steps listed here: https://github.com/openssl/openssl. However, you should be aware that this is a complex process and requires significant technical skill.

I hope this tutorial helps you along your journey to conquer the certificates world! If you have any questions, comments, or requests for new tutorials, please post below.

PowerShell 7.0 or higher require macOS 10.13 and higher. All packages are available on our GitHubreleases page. After the package is installed, run pwsh from a terminal.

Note

PowerShell 7.2 is an in-place upgrade that removes previous versions of PowerShell 6.x and 7.x.

The /usr/local/microsoft/powershell/6 folder is replaced by /usr/local/microsoft/powershell/7.

If you need to run an older version of PowerShell side-by-side with PowerShell 7.2, installthe version you want using the binary archive method.

Supported versions of macOS

The following table is a list of currently supported PowerShell releases and the versions ofWindows they are supported on. These versions remain supported until either the version ofPowerShell reaches end-of-support or the version of[macOS reaches end-of-support][eol-windows].

• A ✅ indicates that the version of the OS or PowerShell is still supported
• A ❌ indicates that the version of the OS or PowerShell isn't supported
• A 🟡 indicates the version of PowerShell is no longer supported on that version of the OS
• When both the version of the OS and the version of PowerShell have ✅, that combination issupported

Support of macOS is defined by Apple. For more information, see:

PowerShell is supported on macOS for the following processor architectures:

Installation of latest stable release via Homebrew on macOS 10.13 or higher

There are several ways to install PowerShell on macOS. Choose one of the following methods:

• Install using Homebrew. Homebrew is the preferred package manager for macOS.
• Install PowerShell via Direct Download
• Install from binary archives.

After installing PowerShell, you should install OpenSSL. OpenSSL isneeded for PowerShell WSMan remoting.

If the brew command is not found, you need to install Homebrew followingtheir instructions.

Now, you can install PowerShell:

Finally, verify that your install is working properly:

When new versions of PowerShell are released, update Homebrew's formulae and upgrade PowerShell:

Note

The commands above can be called from within a PowerShell (pwsh) host,but then the PowerShell shell must be exited and restarted to complete the upgradeand refresh the values shown in $PSVersionTable.

Installation of latest preview release via Homebrew on macOS 10.13 or higher

After you've installed Homebrew, you can install PowerShell. First, install the Cask-Versionspackage that lets you install alternative versions of cask packages:

Now, you can install PowerShell:

Finally, verify that your install is working properly:

When new versions of PowerShell are released, update Homebrew's formulae and upgrade PowerShell:

Note

The commands above can be called from within a PowerShell (pwsh) host,but then the PowerShell shell must be exited and restarted to complete the upgrade.and refresh the values shown in $PSVersionTable.

Installing PowerShell using the Homebrew tap method is also supported for stable and LTS versions.

You can now verify your install

When new versions of PowerShell are released, simply run the following command.

Note

Whether you use the cask or the tap method, when updating to a newer version of PowerShell, usethe same method you used to initially install PowerShell. If you use a different method, opening anew pwsh session will continue to use the older version of PowerShell.

If you do decide to use different methods, there are ways to correct the issue using theHomebrew link method.

Installation via Direct Download

Use the following commands to install PowerShell from the binary archive. Change the download URL tomatch the version you want to install.

Installing dependencies

OpenSSL is required for PowerShell remoting and CIM operations. You can install OpenSSL via MacPortsif needed.

Note

MacPorts and Homebrew can have problems when used to together on the same system. However,Homebrew does not have a package for OpenSSL 1.0. For more information, see theMacPorts FAQ.

1. Install the Xcode command-line tools. The Xcode tools are required by MacPorts.

2. Install MacPorts. If you need instructions, refer to theinstallation guide.

3. Update MacPorts by running sudo port selfupdate.

4. Upgrade MacPorts packages by running sudo port upgrade outdated.

5. Install OpenSSL by running sudo port install openssl10.

6. Link the libraries to make them available to PowerShell:

Uninstalling PowerShell

If you installed PowerShell with Homebrew, use the following command to uninstall:

If you installed PowerShell via direct download, PowerShell must be removed manually:

To remove the additional PowerShell paths, refer to the paths section in this documentand remove the paths using sudo rm.

Mac Install Openssl 1.0

Note

This is not necessary if you installed with Homebrew.

Paths

• $PSHOME is /usr/local/microsoft/powershell/7.1.4/
• User profiles will be read from ~/.config/powershell/profile.ps1
• Default profiles will be read from $PSHOME/profile.ps1
• User modules will be read from ~/.local/share/powershell/Modules
• Shared modules will be read from /usr/local/share/powershell/Modules
• Default modules will be read from $PSHOME/Modules
• PSReadline history will be recorded to ~/.local/share/powershell/PSReadLine/ConsoleHost_history.txt

Openssl Mac Download

The profiles respect PowerShell's per-host configuration. So the default host-specific profileexists at Microsoft.PowerShell_profile.ps1 in the same locations.

PowerShell respects the XDG Base Directory Specification on macOS.

Because macOS is a derivation of BSD, the prefix /usr/local is used instead of /opt. So,$PSHOME is /usr/local/microsoft/powershell/7.1.4/, and the symbolic link is placed at/usr/local/bin/pwsh.

Installation support

Microsoft supports the installation methods in this document. There may be other methods ofinstallation available from other sources. While those tools and methods may work, Microsoft cannotsupport those methods.
