Hash Generator

Generate cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512) for text and files to verify integrity and create checksums.

How It Works

1

Input Your Data

Enter text or upload a file that you want to generate cryptographic hashes for.

2

Select Hash Algorithms

Choose from MD5, SHA-1, SHA-256, SHA-512, or generate multiple hashes simultaneously.

3

Generate and Copy Hashes

View the generated hash values and copy them for verification, storage, or comparison purposes.

Frequently Asked Questions

What's the difference between hash algorithms?

MD5 and SHA-1 are older and faster but less secure. SHA-256 and SHA-512 are more secure and recommended for security-critical applications. SHA-256 is most commonly used today.

Are hash functions reversible?

No, cryptographic hash functions are one-way. You cannot reverse a hash to get the original data, which is why they're used for password storage and data integrity verification.

Why would I need to hash data?

Common uses include verifying file integrity (checksums), storing passwords securely, creating unique identifiers, and detecting data tampering or corruption.

Is my data secure during hashing?

Yes, all hashing happens locally in your browser. Your original data and generated hashes never leave your device.

Can two different inputs have the same hash?

While theoretically possible (called a collision), it's extremely rare with modern algorithms like SHA-256. The probability is so low it's considered practically impossible.
