💡 What is this
Hash Generator
- Generates cryptographic hash digests (MD5, SHA-1, SHA-256, SHA-512) from text input.
- SHA-256 and SHA-512 use the browser's native Web Crypto API for maximum security.
- MD5 uses a lightweight JavaScript implementation.
📖 How to use
Step by Step
- Enter or paste text in the input field
- Select the hash algorithm from the dropdown
- Click Generate Hash to compute the digest
- Copy the resulting hex string
🎯 Use cases
When to use
- Verifying file integrity with checksums
- Creating content fingerprints
- Comparing data without revealing originals
- Generating cache-busting keys
Frequently Asked Questions
Is my data sent to a server?▾
No. All hashing is done entirely in your browser using the Web Crypto API (for SHA) or a pure JavaScript MD5 implementation. No data ever leaves your device.
Is MD5 secure?▾
MD5 is considered cryptographically broken and should not be used for security. It's still useful for checksums and non-security fingerprinting. Use SHA-256 or SHA-512 for security.
Can I hash files?▾
Currently this tool hashes text input. For file hashing, you can paste file contents or use a dedicated file hash tool.
