Hash Generator — MD5, SHA-1, SHA-256 and SHA-512
A hash function turns any text or file into a fixed-length fingerprint. This free hash generator computes MD5, SHA-1, SHA-256 and SHA-512 side by side, so you can compare checksums, verify downloads, or watch the avalanche effect turn a tiny input change into a totally different digest.
Hashing runs entirely in your browser using the Web Crypto API (with CryptoJS for MD5). Type or drop a file, get all four hashes instantly, and copy any of them with one click — your data is never uploaded to a server.
Four algorithms at once
Get MD5 (128-bit), SHA-1 (160-bit), SHA-256 (256-bit) and SHA-512 (512-bit) digests from the same input in a single click — no need to run four separate tools.
Hash text or whole files
Switch between Text and File mode to hash a pasted string or any file on your device. Files are read locally and never leave your computer.
Why hashing matters
Developers use hashes to verify file integrity, store passwords safely, generate cache keys, and sign documents. SHA-256 and SHA-512 are the secure choices for new projects; MD5 and SHA-1 remain useful only for non-security checksums.
How to use
- Choose Text mode to hash a pasted string, or File mode to hash a file.
- Enter your text or drop a file into the upload zone.
- Click Generate Hashes — all four digests appear instantly.
- Use the Copy button beside any hash to copy it to your clipboard.
Frequently Asked Questions
What is a hash function?
A hash function is a one-way algorithm that converts any input into a fixed-size string of characters. The same input always produces the same output, but the output cannot be reversed to recover the input.
Which hash algorithm should I use?
Use SHA-256 or SHA-512 for anything security-related, such as password storage or integrity checks. MD5 and SHA-1 are considered broken for security purposes but still work fine as simple checksums.
Can I reverse a hash to get the original text?
No. Hash functions are one-way. However, attackers can guess common inputs and compare hashes (rainbow tables), so never rely on a plain hash to protect secrets — use a proper password-hashing scheme instead.
Is my data uploaded to a server?
No. All hashing runs locally in your browser using the Web Crypto API, so your text and files never leave your device.
Can I hash a file instead of text?
Yes. Switch to File mode and drop any file into the upload zone — the tool reads it locally and computes all four hashes without uploading anything.
