SHA1 Hash Lookup
Compare a SHA1 hash against a list of words (not true decryption).
About this tool
Our SHA1 decrypt tool looks up common SHA-1 hashes and shows the known plaintext if found. For recognizing common strings only. Not for cracking passwords. Use only for hashes you’re allowed to check.
SHA1 is one-way; it cannot be reversed. Enter a hash and candidate passwords (one per line) to verify which one matches.
How to use
Paste a SHA1 hash and possible words. The tool checks for a match in your browser.
