Hash Generator — Free Online Tool
Generate SHA-1, SHA-256, SHA-384 and SHA-512 hashes from any text.
About Hash Generator
The Hash Generator computes SHA-1, SHA-256, SHA-384, and SHA-512 digests of any text directly in your browser. Hashes are essential for verifying file integrity, generating checksums, and building fingerprints of data, and seeing all four at once makes comparison quick.
Powered by the standard Web Crypto API, every digest is produced locally on your device, so your input never travels over the network. That makes the tool both fast and private, with a one-click copy button for each individual hash.
How to Use Hash Generator
- Type or paste the text you want to hash into the input box.
- Click 'Generate Hashes' to compute all four digests at once.
- Read the SHA-1, SHA-256, SHA-384, and SHA-512 results in their fields.
- Use the copy button beside any hash to copy that digest.

Frequently Asked Questions
Which hash algorithms are supported?
The generator computes SHA-1, SHA-256, SHA-384, and SHA-512 digests at the same time using the browser's built-in Web Crypto API, so you get all four results from a single click.
Are the hashes computed securely in my browser?
Yes. Hashing runs locally through crypto.subtle.digest, so your input text is never transmitted to any server and the results are generated entirely on your device.
Why should I avoid SHA-1 for security?
SHA-1 is considered cryptographically weak and vulnerable to collision attacks. It is included for compatibility and checksums, but for security-sensitive work prefer SHA-256 or stronger.
Can I hash passwords with this tool?
Plain hashing is not suitable for storing passwords because it lacks salting and key stretching. Use a dedicated password hashing algorithm like bcrypt or Argon2 for that purpose.
Will the same text always produce the same hash?
Yes. Hash functions are deterministic, so identical input always yields the identical digest, which is exactly why hashes are useful for verifying data integrity.
