How to Install openSSL

Install OpenSSL on macOS

Option 1: Install via Homebrew (Recommended)
If you have Homebrew:

				
					brew update
brew install openssl

After installation, link it:

				
					brew link openssl --force

But if it says linking is not allowed, use this:

				
					echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

For Apple Silicon (M1/M2/M3), use:

				
					echo 'export PATH="/opt/homebrew/opt/openssl/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

Verify:

				
					openssl version

Option 2: Install Without Homebrew
Download OpenSSL source:
https://www.openssl.org/source/
Then run:

				
					./Configure darwin64-x86_64-cc
make
sudo make install

(But Homebrew is MUCH easier.)

Install OpenSSL on Windows
Option 1: Use Precompiled Installer (Recommended)
Download from a trusted source like ShiningLight Productions:

Steps:

Verify: Open Command Prompt:

				
					openssl version

Option 2: Install Using Chocolatey (Windows Package Manager)

If you have Chocolatey installed:

				
					choco install openssl

Or specific version:

				
					choco install openssl --version=3.2.0

Verify:

				
					openssl version
