Hash Generator
Hashing converts text into a fixed-length fingerprint, useful for verifying data integrity or comparing values without storing the original. This tool computes SHA-256 and SHA-1 hashes live as you type, using your browser's native cryptography engine.
How to Use This Tool
- Type or paste the text you want to hash.
- The SHA-256 and SHA-1 hashes update automatically.
- Copy the hash you need by selecting it manually.
Why Use ToolVigo's Hash Generator
- Uses the browser's native Web Crypto API for accurate, standard-compliant hashes.
- Computes both SHA-256 and SHA-1 simultaneously.
- Nothing is sent to a server — hashing happens entirely client-side.
Privacy & Security
This tool runs entirely in your browser. Your input is never uploaded to ToolVigo's servers, and nothing is stored once you leave the page.
Frequently Asked Questions
Why isn't MD5 offered?
MD5 is cryptographically broken and has been removed from browsers' built-in Web Crypto API, so this tool offers SHA-1 and SHA-256 instead, which browsers support natively and securely.
Can a hash be reversed back to the original text?
No — hashing is a one-way function. The same input always produces the same hash, but the hash cannot be converted back into the original text.
What is a hash typically used for?
Common uses include verifying file integrity, checking password matches without storing plaintext, and detecting duplicate or tampered data.
