What it does

Scan any pasted text - server logs, HTTP headers, config blobs, chat dumps - and pull out every URL, email, IPv4 address, IPv6 address, cryptographic

hashhashA one-way function that maps data of any size to a fixed-length digest. Same input, same digest; any change, different digest; not reversible.

, and domain name it contains. Each kind is listed separately, deduplicated, and shown with a count and a one-click copy button. The tool runs entirely in your browser; nothing you paste is uploaded.

Use it to triage a suspicious log line, harvest indicators (IPs, hashes, domains), or pull contact data out of a document in a single pass.

How to use it

1. Paste (or type) your text into Text or log - hit Sample to load a worked example.
2. Toggle the kind chips under Extract - URLs, Emails, IPv4, IPv6, Hashes, Domains - to enable or disable each. Disabled kinds are hidden from the results.
3. Read each result box: the count is on the left, Copy on the right, with matches listed one per line below.
4. Use Clear to reset the input.

Examples

Input:

login from 10.0.0.42 (2001:db8::1) as admin@cosmolabs.org
fetch https://cosmolabs.org/page?ref=email
sha256 e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

Output (excerpt):

• URLs → https://cosmolabs.org/page?ref=email
• Emails → admin@cosmolabs.org
• IPv4 → 10.0.0.42
• IPv6 → 2001:db8::1
• Hashes → e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
• Domains → cosmolabs.org

Disabling every chip except Hashes returns only the SHA-256 line.

Good to know

• Private: runs 100% client-side - your text never leaves the tab.

• HashHashA one-way function that maps data of any size to a fixed-length digest. Same input, same digest; any change, different digest; not reversible.

  lengths recognized: 32 (MD5), 40 (SHA-1), 64 (SHA-256), 128 (SHA-512) hex characters.
• IPv6 is matched permissively (compressed :: or the full 8-group form); IPv4 is format-only (x.x.x.x) and does not validate the 0-255 range, so version strings like 1.2.3.4 are captured too.
• An email also contributes its domain to the Domains list.
