Introducing HashLens — The Hash Identifier the Chrome Web Store Never Had

We're excited to launch HashLens, the latest extension in the UnifyBrowse suite.

The Problem

Every existing hash extension on the Chrome Web Store does the same thing: you give it text, it spits out a hash. That's a hash generator. Useful, but it solves the easy problem.

The hard problem — the one security researchers, CTF players, and developers actually hit every day — is the opposite: you're staring at an unknown string like 5d41402abc4b2a76b9719d911017c592 and you have no idea what algorithm produced it. Is it MD5? NTLM? MD4? They all produce 32 hex characters. To find out, you leave the browser, open a separate website, paste the hash, and wait for an answer.

There is no Chrome extension for this. We checked. Every tool on the store is a generator, not an identifier. HashLens fills that gap.

The Solution

HashLens lets you paste any hash and instantly know what it is — the algorithm, its security status, its Hashcat mode number, and its John the Ripper format string, all in one view with zero round trips to the internet.

✨ Key Features

• Instant identification — Paste any hash and HashLens matches it against 20+ algorithms by length, character set, and known prefixes. bcrypt's $2a$ prefix, SHA-512crypt's $6$, Argon2's $argon2id$ — all recognised without you counting characters.
• Hashcat + JtR modes inline — Every result shows the Hashcat mode number (e.g. MD5 = 0, SHA-256 = 1400) and John the Ripper --format flag with a one-click copy. No more cross-referencing cheat sheets mid-CTF.
• Security ratings — MD5 and SHA-1 are flagged Broken. bcrypt, Argon2, and SHA-3 are marked Secure. Every rating has a plain-English reason behind it.
• Hash generator — Generate hashes from any text input across 9 algorithms at once: MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-512, and RIPEMD-160. Output in lowercase hex, uppercase hex, or Base64.
• File Hash Verifier — Opens in a dedicated browser tab so large file hashing can't be interrupted by the popup closing. Drop any file, select your algorithm, paste the expected checksum from the official page, and get an immediate match or mismatch — without opening a terminal.
• Clipboard detection — Open the popup after copying a hash and it pre-fills and identifies it automatically.
• Context menu — Right-click any selected text on any page to identify it or generate its hash without opening the popup at all.

🔒 Zero Trust Required

HashLens requests the minimum permissions needed and nothing more. No host permissions. No access to your browsing history. No analytics. The extension runs on Manifest V3 — Chrome's most secure extension architecture. Hash strings, file contents, and clipboard data are processed in your browser using the @noble/hashes cryptographic library and never leave your machine. The File Verifier uses chunked streaming so even 2 GB ISOs are processed locally without a single byte being uploaded.

🚀 Get Started

1. Install HashLens from the Chrome Web Store
2. Click the extension icon — if your clipboard contains a hash, it identifies it immediately
3. Use the Identify tab to analyse unknown hashes
4. Use the Generate tab to hash any text across multiple algorithms at once
5. Click Verify File Integrity to open the file verifier in a dedicated tab
