Signal is one file. Installing it means requesting it, checking it is the genuine release, and putting it where you will run it.

Where to get it

Signal Community is free, and every copy comes from the Intrusion Academy website: request it on the contact form. A download link is emailed to you at once. It opens a download page for 15 minutes; if it has closed, one click on it emails a new link. Signal is not published anywhere else, so a copy from another place is not the genuine release.

What you get

What it is

signal.exe

The program, code-signed. No installer, no runtime, no dependency.

Its SHA-256

Shown on the download page, to check the file you saved.

Install

  1. Request and download

    Request Signal on the contact form, open the emailed link and save signal.exe into one folder, for example C:\Tools\Signal.

  2. Check the hash

    Compare the file's SHA-256 with the one on the download page. They must be identical.

  3. Check the version

    Run signal version. It prints the version, and the license line.

  4. Allow it in your security products

    Allow the release's SHA-256 in your antivirus and EDR before running it across a fleet. See Antivirus and EDR.

PowerShell Check the hash 
Get-FileHash .\signal.exe -Algorithm SHA256
PowerShell Check the version 
.\signal.exe version

Updating later

signal update tells you whether a newer version exists. A new version is requested the same way as the first one. See Updating Signal.
