How to Verify an Onion Link

How to verify an onion link is a procedure. Clone pages win when you skim the first dozen characters, or when a directory paints a green dot because something answered.

Full-string comparison

A v3 host is 56 lowercase characters, then .onion. Compare every character with a string already saved from a Darkbrief entry, such as Torzon market link. A matching prefix is how the kit keeps a familiar start. This page does not reprint foreign onions “for comparison.”

0/O, l/1, rn/m

Phishing kits swap lookalike characters in the middle and leave the opening alone. Read the monospace block on the entry. A logo, a countdown, or a review score is not that block.

Phrase and PGP before a password

If the page shows an anti-phishing phrase or a canary, confirm it before any password. A signed list only counts when the fingerprint is one you already stored. A fingerprint printed next to the claim is the claim. Nexus in October 2026 is the reverse case: no signed farewell, then a reported key leak on 7 October. See PGP and October 2026.

Never from ads or a “new mirror” chat

Exact-match ads, a Telegram “support” account, and a post-downtime message that offers a fresh link are hostile until the string matches. Clearnet hubs in scan sources redistribute talk. They are not logins. Bookmark the filed host and a second one from the same entry. One bookmark is not a spare.

Stop rules

The page loaded. That is not proof. The first characters match. That is not proof. Only the full string in this brief, then the phrase, then PGP.
