• Main Site Downtime: If the official site experiences outages or maintenance, mirrors serve as reliable alternatives for downloading the browser.

Reliable access to Tor mirrors is particularly important. Users should be cautious, as not all mirrors are trustworthy. To ensure safety, verify the authenticity of downloaded files by checking the accompanying .asc signature file. This file uses OpenPGP signatures to confirm that the download has not been tampered with (2).

To verify a downloaded file:

1. Import the Tor Browser Developers' signing key (0xEF6E286DDA85EA2A4BA7DE684E2C6E8793298290).
2. Use a tool like GnuPG to check the .asc signature against the installer (2).

A successful verification will yield a message indicating a ‘Good signature from Tor Browser Developers’ (2).

Using legitimate mirrors minimizes the risk of downloading malicious software. Always cross-reference multiple sources when accessing unofficial links to ensure they are valid (3). Avoid mirrors that redirect to different .onion addresses or clearnet URLs without explanation, as this could indicate a compromised site (3).

Common Mistakes and Misconceptions#

Relying on Unverified Sources for Mirror Links

Many users search for Tor Browser mirror links through general search engines or untrusted forums. This practice can lead to downloading compromised software or encountering phishing attempts. Always cross-reference multiple reliable sources, such as the site's primary .onion address, PGP-signed mirror lists, and well-known darknet directories, to confirm a mirror's legitimacy (3).

Skipping Signature Verification After Download

A common oversight is to download the Tor Browser from a mirror and proceed with installation without verifying the file's signature. This leaves you vulnerable to installing a tampered version of the browser. Every Tor Browser download file, whether from the official site or a mirror, includes a '.asc' signature file, which is an OpenPGP signature used to verify authenticity (2). You must import the Tor Browser Developers signing key (0xEF6E286DDA85EA2A4BA7DE684E2C6E8793298290) and use a tool like GnuPG to verify the '.asc' file against the installer (2). A successful verification will show a message like "Good signature from 'Tor Browser Developers (signing key) [email protected]'" (2).

Ignoring Unexpected Redirects

Users sometimes overlook or dismiss unexpected redirects when attempting to access a mirror site. Legitimate mirrors should not redirect users to different .onion addresses or clearnet URLs without a clear explanation (3). Unexpected redirects, especially to login pages or download prompts, are a strong indicator of a compromised mirror and should prompt immediate disengagement (3).

Assuming All Mirror Sites are Equally Secure

Not all mirror sites offer the same level of security or reliability. While official mirrors provided by organizations like EFF or La Cebolla (Calyx Institute) are trustworthy (1), unofficial mirrors can vary greatly in their security practices. Always ensure the connection to the mirror is secured using HTTPS (1). Additionally, be wary if a mirror's TLS certificates are inconsistent with the primary site, as this could indicate a security issue (3).

Not Using GetTor When Official Sites are Blocked

When the official Tor Project website is blocked, some users might continue to search for direct mirror links, potentially encountering malicious sites. GetTor provides a secure alternative by delivering Tor Browser download links via email or messaging apps, bypassing direct website access (1). This method is especially useful in highly censored regions where direct access to official sites or mirrors is restricted.

Neglecting Tor Browser Logs for Troubleshooting

When connection issues arise, users often restart the browser or their computer without checking the Tor Browser logs. These logs provide crucial diagnostic information. For instance, a 'Proxy connection failure' can indicate an offline or blocked bridge (5), while 'Can't reach guard relays' or 'Failed to complete TLS handshake' often point to network censorship (5). Reviewing logs helps identify the root cause, such as needing to request new bridges [11, 12].
