Hash Generator (SHA-1, SHA-256)

Generate Text Hashes

Enter text below to generate its SHA-1 and SHA-256 hash values. Hashes are one-way functions useful for data integrity checks.

How to Use

1. Paste or type the text you want to hash into the "Input Text" area.
2. Click the "Generate Hashes" button.
3. The SHA-1 and SHA-256 hash values (hexadecimal representation) will appear below.
4. Click the "Copy" button next to a hash to copy it to your clipboard.

Note: MD5 is generally considered insecure and is not typically available in modern browser crypto APIs.

Why Use Hashes?

• Data Integrity: Verify that data hasn't been tampered with by comparing hash values.
• Password Storage (Salted): Store hashes of passwords (with unique salts) instead of plain text for security (server-side).
• Checksums: Create a short fingerprint of data for quick comparison.
• Digital Signatures: Used as part of digital signature algorithms.
