About Hash Generator
Hash Generator creates cryptographic hashes from text input. Hashing is a one-way function that converts data into a fixed-size string, commonly used for data integrity verification, password storage, and digital signatures.
Features
- ✓Generate MD5 hashes (128-bit)
- ✓Generate SHA-256 hashes (256-bit)
- ✓Real-time hash generation as you type
- ✓Copy individual hashes with one click
- ✓Works offline in your browser
- ✓No server uploads - complete privacy
How to Use
- 1.Enter or paste text in the input box
- 2.Hashes are generated automatically
- 3.Click "Copy" to copy MD5 or SHA-256 hash
- 4.Use hashes for verification or comparison
⚠️ Security Note
MD5 is not cryptographically secure and should not be used for security purposes. Use SHA-256 or stronger algorithms for password hashing and security-critical applications. For password storage, use bcrypt, scrypt, or Argon2.
How to Use
Paste text into the input and the MD5 and SHA-256 hashes update instantly. I use SHA-256 for integrity checks and avoid MD5 for security use cases.
- Enter or paste your text.
- Copy the MD5 or SHA-256 hash.
- Use SHA-256 for verification tasks.
- Keep sensitive inputs local.
Use Cases
Hashes are useful for:
- File integrity checks after downloads.
- Deduplication of content.
- Cache keys and ETags.
- Digital signing workflows as pre-hash input.
Tips & Best Practices
- Prefer SHA-256 for security work.
- Avoid MD5 for passwords or signatures.
- Salt password hashes with bcrypt/Argon2.
- Verify checksum matches exactly.

FAQ
Is MD5 secure?
No. MD5 is broken for security use cases.
Can I hash files?
This tool hashes text input. For files, paste the contents.
Is the hashing offline?
Yes. Everything runs locally in your browser.
Which hash should I use?
Use SHA-256 for integrity and security checks.
