Privacy First

Processing is 100% local. Your data never leaves your browser and isn't sent to any server.

MD5 Warning

MD5 and SHA-1 are cryptographically broken. Use them only for checksums, never for security or passwords.

Salted Hashes

For password storage, simple hashing isn't enough. Use salted algorithms like Argon2 or bcrypt.

## Verify Data Integrity A "hash" is a digital fingerprint of data. Even a single changed character in a document results in a completely different hash. The **Hash Generator** supports the most common algorithms used for file verification, password storage concepts, and digital signatures. ### Supported Algorithms - **MD5**: Fast and common, but no longer secure for passwords. - **SHA-1**: Legacy government standard (deprecated for security). - **SHA-256**: The industry standard for security (used in Bitcoin, SSL). - **SHA-512**: Higher security with a longer fingerprint. ### Use Cases - **File Verification**: Check if a downloaded file matches the original by comparing hashes. - **Data Integrity**: Ensure a message hasn't been tampered with during transmission. - **Developer Testing**: Generate test hashes for your application's logic.

Common Questions

QCan I decrypt a hash?

No. Hashing is a one-way process. You cannot turn the fingerprint back into the original text. You can only verify if a specific text produces that fingerprint.

QWhy is MD5 'insecure'?

Computers are now fast enough to find two different texts that produce the same MD5 hash (a 'collision'). Do not use MD5 for security signatures.

QIs my text sent to a server?

No. All hashing is performed locally in your browser using the Web Crypto API.
