How long is a SHA1 hash?

A standard SHA-1 digest is 160 bits and is normally written as exactly 40 hexadecimal characters.

Can this tool crack salted SHA1 hashes?

No. This page accepts only a bare 40-character SHA-1 digest. Salted or application-specific constructions require format-specific, explicitly authorized analysis.

How many hashes can I search for free?

Each verified run accepts up to 100 hashes. The server also enforces a maximum of 1,000 processed hashes per visitor per UTC day.

Why is Cloudflare Turnstile required for every run?

Every lookup uses external database capacity. Single-use Turnstile verification, request throttling and a daily weighted quota work together to prevent automated abuse.

Does a “not found” result mean the plaintext cannot be recovered?

No. It means the active lookup databases did not return a known match. This free utility does not perform an exhaustive brute-force or dictionary attack.

Can I use this utility on hashes from another person or system?

Only when you own the data or have explicit authorization covering password recovery. Public exposure or possession of a hash is not permission to recover or use its plaintext.

Ready for an authorized lookup

Every run requires Cloudflare verification and is protected by strict per-run and daily limits.

Use this lookup only for hashes you own or are explicitly authorized to recover. Never use a recovered plaintext to access an account, system or dataset outside the approved scope.

Focused SHA-1 hash lookup

This focused utility accepts unsalted SHA-1 digests represented by exactly 40 hexadecimal characters.

SHA-1 validation

Reject malformed input before any lookup and accept only complete SHA-1 hexadecimal digests.

Known-plaintext search

Query multiple lookup sources through the protected DorkPlus server and clearly separate matches from unresolved hashes.

Bulk input

Paste up to 100 hashes, remove duplicate lines automatically and preserve the submitted order in the result list.

Daily abuse protection

Cloudflare Turnstile protects every run, with a strict allowance of 1,000 processed hashes per visitor each day.

Copy and TXT export

Copy the complete output or download found and unresolved hashes as a plain UTF-8 text report.

Upgrade path for scale

Move legitimate high-volume recovery work to HPlus when the free browser workflow is no longer enough.

Protected lookup

Transparent processing and strict limits

Submitted hashes are sent to the DorkPlus server and its lookup providers only after Turnstile verification. Do not submit personal data, plaintext passwords or hashes you are not authorized to analyze.

100

Hashes per run

Each verified request accepts at most 100 valid hashes. Duplicate lines are searched only once.

1,000

Hashes per day

An atomic server-side quota prevents a visitor from exceeding the free daily allowance.

How to search a SHA1 hash database

SHA-1 produces a 160-bit digest. A result is available only when the same digest and plaintext have already been indexed by a lookup source.

Prepare valid SHA-1 values

Use one complete hash per line. This page validates SHA-1 format before opening the verification step.

Verify every lookup run

Select Search hash databases and complete the Cloudflare Turnstile challenge. Tokens are single-use and bound to this action.

Review found and unresolved hashes

A Found result contains a known plaintext match. Not found means the current sources did not contain a matching record; it does not prove that recovery is impossible.

Copy or export your report

Copy the result list or download a TXT file. Use recovered data only within the system and scope that authorized the lookup.

Accurate terminology

SHA-1 is stronger than MD5, but still legacy

SHA-1 produces a longer digest than MD5, but it is still a fast, deterministic algorithm. Unsalted SHA-1 password records can therefore be compared efficiently against databases of previously calculated values.

Modern password storage should use unique salts and slow password-hashing algorithms. This utility is intended for authorized legacy recovery and training—not for accessing accounts or data without permission.
