Free Online Hash Generator
Type or paste any text below and instantly generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes. Everything is computed locally in your browser — your data never leaves your device.
How to Use the Hash Generator
1. Enter Your Text
Type or paste any text, password, or string into the input box.
2. Generate the Hashes
Click Generate Hashes. All five algorithms — MD5, SHA-1, SHA-256, SHA-384 and SHA-512 — are calculated at once.
3. Copy the Result
Each hash appears in its own read-only box. Click the copy button next to any hash to copy it to your clipboard.
What is a Hash Generator?
A hash generator converts any input text into a fixed-length string of characters called a hash digest. Hashing is one-way, meaning you cannot reverse a hash back to its original text, which makes it ideal for verifying data integrity, storing passwords securely, and generating checksums.
This tool supports the five most widely used algorithms: MD5 (128-bit), SHA-1 (160-bit), SHA-256 (256-bit), SHA-384 (384-bit), and SHA-512 (512-bit). The SHA-256, SHA-384 and SHA-512 hashes are computed using the Web Crypto API built into your browser, while MD5 uses a well-known pure JavaScript implementation.
Because all computation happens locally, your text is never uploaded to any server — it is a fast, private and completely free online hash generator.
