Add OpenSSL to PATH on Windows

Option A — User PATH (recommended)

1. Open Settings → System → About → Advanced system settings.
2. Click Environment Variables….
3. Under User variables, select Path → Edit → New.
4. Add the OpenSSL bin folder, e.g.: C:\\Program Files\\OpenSSL-Win64\\bin
5. Confirm all dialogs with OK, then open a new terminal (Command Prompt or PowerShell).

This affects only your user account. No admin rights needed.

Option B — System PATH (all users)

1. Open Advanced system settings → Environment Variables….
2. Under System variables, select Path → Edit → New.
3. Add the same bin path, e.g.: C:\\Program Files\\OpenSSL-Win64\\bin
4. Click OK to save. Open a new terminal.

Requires administrator rights. Be careful editing the system PATH.

Option C — Command line (User PATH)

Command Prompt:

setx PATH "%PATH%;C:\Program Files\OpenSSL-Win64\bin"

PowerShell:

[Environment]::SetEnvironmentVariable("Path", $env:Path + ";C:\Program Files\OpenSSL-Win64\bin", "User")

Open a new terminal after running these commands. If PATH grows very long, prefer the GUI editor.

Verify it works

1. Open a new Command Prompt or PowerShell window.
2. Run openssl version — it should print the version line.
3. Check the resolved path: where openssl (cmd) or Get-Command openssl (PowerShell).

If you see DLL errors, go to Fix DLL Error. If the command is not found, recheck your PATH entries.
