Verifying Downloads

You should verify all downloads. Even though https:, the .dmg format, and the application's macOS digital signature provide some protection, they can be circumvented.

Verifying Hashes

Comparing the SHA256, SHA1, and MD5 hashes of your downloaded file with the official published ones will provide additional assurance that the download is legitimate and has not been modified. You can compare the hashes with programs included with macOS without the need to install additional software.

To compute the hashes of a file you've downloaded, type the following into /Applications/Utilities/Terminal:

          shasum -a 256 path-to-the-file
          openssl sha1 path-to-the-file
          openssl md5 path-to-the-file

Then compare the computed hashes with the values shown near the link for the downloaded file.

(Don't type 'path-to-the-file' — type the path to the file, that is, the sequence of folders that contain the file plus the file name (e.g. /Users/janedoe/Desktop/Tunnelblick_3.7.2a_build_4851.dmg). An easy way to get it into Terminal is to drag/drop the file anywhere in the Terminal window. The pointer will turn into a green and white plus sign ("+") to indicate the path will be dropped. So you would type 'shasum -a 256 ' — with a space after the "256" — and then drag/drop the disk image file anywhere in the Terminal window.)

For additional assurance that the hashes displayed on this site have not been compromised, the hashes are also available in the description of each "Release" on Tunnelblick's GitHub site, which is hosted and administered separately from this site.

Verifying GnuPG Signatures

Recent Tunnelblick disk images are also signed with GnuPG version 2.

To prepare for verifying signatures, you should download and install GnuPG 2.2.3 or higher, and then add the Tunnelblick Security GnuPG public key (key ID 6BB9367E, fingerprint 76DF 975A 1C56 4277 4FB0 9868 FF5F D80E 6BB9 367E) to your trusted GnuPG keyring by typing the following into /Applications/Utilities/Terminal:

          gpg --import TunnelblickSecurityPublicKey.asc.

To verify the signature of a file, download the corresponding signature file and then type the following into /Applications/Utilities/Terminal:

          gpg --verify path-to-the-signature-file path-to-the-disk-image-file

The result should be similar to the following:

          gpg: Signature made Sat Dec 16 19:17:03 2017 EST
          gpg: using RSA key B4D96F0D6A58E335A0F4923A2FF3A2B2DC6FD12C
          gpg: Good signature from "Tunnelblick Security <tunnelblicksecurity@protonmail.com>" [ultimate]


User Contributions

These downloads have been contributed by users and usually help deal with special circumstances. They are not endorsed or checked by the Tunnelblick project, and you use them at your own risk. To contribute a download, send it to the developers or post it on the Tunnelblick Discussion Group.

Before using these scripts, please read Tunnelblick and VPNs: Privacy and Security. (Actually, everyone using a VPN should read that!)

Note: these scripts are executed as root. Instructions for using scripts.

  Scripts to Unload Cisco Tun Kext: user-contributed-001-pre-post.zip
  SHA1: d3b09a2284de2862be7d55059581a85698930b28 MD5: f6f484864697607ee5c7206a5b056b12
  Contributed by "petiepooo".
These scripts unload the Cisco AnyConnect tun kext before a Tunnelblick connection is started, and reload the Cisco tun kext after a Tunnelblick connection is stopped. (The Cisco kext interferes with Tunnelblick's operation of tun connections.)
 
  Scripts to Mount/Unmount a Volume: user-contributed-002-mount-unmount-volume.zip
  SHA1: eb69727620fa8c46633d9ccf9f86c4b258fea7e6 MD5: 5b3b04bea43403b2a709aaa4c92d7473
  Contributed by John Griffis.
These scripts mount a volume after a configuration is connected and unmount it when the configuration is disconnected. Scripts must be edited before use (in any plain-text editor) to specify details of the volume to be connected. For a note about connecting to a CIFS account, see this discussion.
 
  Scripts to Monitor Connection Time and Bandwidth Use: user-contributed-003-monitor-uptime-and-bandwidth.zip

  Contributed by "vkapovit".
  These scripts provide a mechanism for the user to be alerted when the VPN has been up for more than 20 minutes or when bandwidth has exceeded 100MB. See this discussion for details. Requires Growl.
Includes compiled binaries; use at your own risk.
 
  Scripts to Launch and Kill a Program: user-contributed-004-launch-kill-program.zip
  SHA1: 977aa7cc55f3e191b50057fe766c426af01808eb MD5: beccc55286b398fe0a8bcb798e25a883
  Contributed by "anonymous".
  These scripts cause a program to be launched when a VPN is connected and then killed when the VPN is disconnected. It can be used with a torrent program, for example, so that the program is only active when the VPN is connected.
Note that there may be a short time after the VPN has been disconnected before the program is killed.
 

Download Integrity

In June 2015 there was much discussion (and outrage) about SourceForge providing downloads that contain unwanted or malicious software; SourceForge has changed their policies to help avoid this. Tunnelblick binaries were hosted on SourceForge from the fall of 2013, when Google Code stopped hosting new binaries, until 2015-07-17, when they were moved from SourceForge to GitHub.

Tunnelblick protects against unwanted software insertions by publishing the SHA1 and MD5 hashes for each of our downloads. You should verify the hashes of all Tunnelblick downloads by following the instructions above.

Additional safeguards automatically protect updates performed by Tunnelblick's built-in update mechanism:

  • Updates are controlled by tunnelblick.net and all update data is transported via https:
  • Update downloads contain digital signatures to verify they have not been modified. (This is in addition to the macOS digital signature of the Tunnelblick application itself.) See Digital Signatures.

Downloading and Installing on macOS Mojave or Higher

When Tunnelblick is installed after being downloaded normally, macOS Mojave sends information to Apple (it "phones home") [1]. It is assumed, but has not been verified, that macOS Catalina also does this.

This behavior is considered by some to be a violation of privacy. If you want to avoid having macOS Mojave "phone home" when you install Tunnelblick, you can do the following to download Tunnelblick to your Desktop:

  1. Open the Terminal application located in /Applications/Utilities.
  2. Type (or copy/paste) "curl --location --output ~/Desktop/Tunnelblick.dmg " into Terminal without the quotation marks (the space after ".dmg" is important).
  3. In your browser, instead of clicking on the link to download Tunnelblick, Control-click the link and select "Copy Link" (Safari), "Copy Link Location" (Firefox), or "Copy Link Address" (Chrome).
  4. Click in the Terminal window to select it for input, then Paste (Command-V). A URL starting with https://tunnelblick.net/release/ should appear after the ".dmg ".
  5. Press the enter/return key on the keyboard.
  6. You will see two or more progress bars showing the timing of downloads [2].
  7. Verify the download.
  8. Double-click the downloaded Tunnelblick disk image file on your Desktop to open the Tunnelblick disk image, then double-click the Tunnelblick icon in the window that appears to install Tunnelblick.

This will download the file to your Desktop without the flag that indicates the file was downloaded from the Internet. When that flag is present, macOS Mojave "phones home" when the downloaded file is double-clicked; when the flag is not present, macOS Mojave doesn't.

[1] This isn't something peculiar to Tunnelblick – Mojave does this for any program or document downloaded from the Internet using most browsers and some other programs.

[2] Tunnelblick downloads are redirected from the tunnelblick.net website to GitHub, which then redirects them further. Typically two or more tiny downloads (a few hundred bytes each) provide information about the redirection, and the final larger download is the desired file.
