🔐 Password Hash Generator

Generate secure password hashes using MD5, SHA1, SHA256, SHA512, and Bcrypt algorithms

How to Use the Password Hash Generator

Generate secure password hashes using various algorithms. Perfect for developers, security professionals, and anyone needing to create hashed passwords.

  1. Enter your password or text in the input field
  2. Select your preferred hashing algorithm
  3. Click "Generate Hash" to create the hash
  4. Copy the generated hash using the copy button

🔐 Understanding Hash Algorithms

  • MD5: Fast but not recommended for security. Good for checksums.
  • SHA1: Better than MD5 but also considered weak for security.
  • SHA256: Strong cryptographic hash, part of the SHA-2 family.
  • SHA512: Even stronger than SHA256, produces longer hashes.
  • Bcrypt: Best for password storage. Includes automatic salting and is computationally intensive.

⚠️ Important Security Notes

  • Never use MD5 or SHA1 for storing passwords - they are not secure
  • Always use Bcrypt or similar algorithms for password storage
  • These hashes are one-way - you cannot reverse them to get the original password
  • For production systems, always add salting and use secure libraries

Frequently Asked Questions

What is password hashing?

Password hashing is the process of converting a password into a fixed-length string of characters using a mathematical algorithm. This one-way process makes it impossible to retrieve the original password from the hash, providing security for stored passwords.

Which algorithm should I use?

For password storage, always use Bcrypt or similar modern algorithms like Argon2. For checksums and data integrity, SHA256 or SHA512 are good choices. Avoid MD5 and SHA1 for security purposes.

Can I reverse a hash to get the original password?

No, hashing is a one-way function. You cannot reverse a hash to get the original password. This is what makes hashing secure for password storage.

Why does Bcrypt generate different hashes each time?

Bcrypt automatically includes a random salt in each hash. This means the same password will produce different hashes each time, which is a security feature that prevents rainbow table attacks.

Is this tool safe to use for sensitive passwords?

While all processing happens in your browser or on the server without storing data, we recommend not using real passwords in online tools. Use this for testing and learning purposes only.
