Password Hash Generator

Generate cryptographic hashes (SHA-256, SHA-512, SHA-1) for passwords and data.

⚠️ Security Warning:

  • These are simple cryptographic hashes, not password hashing algorithms
  • For password storage, use bcrypt, argon2, or PBKDF2
  • Simple hashes are vulnerable to rainbow table attacks
  • Always use salting and key stretching for password storage

How to Use Password Hash Generator

  1. 1

    Enter your password or text to hash.

  2. 2

    Select hash algorithm (SHA-256, SHA-512, or SHA-1).

  3. 3

    Click "Generate Hash" to create the hash.

  4. 4

    Copy the generated hash for use in your application.

Frequently Asked Questions

Should I use this for storing passwords?

No - use bcrypt, argon2, or PBKDF2 for password storage. Simple SHA hashes are vulnerable to rainbow table attacks.

What is the difference between SHA-256 and SHA-512?

SHA-512 produces a longer 512-bit hash compared to SHA-256's 256-bit, providing higher collision resistance but slower computation.

Is SHA-1 still secure?

No, SHA-1 is considered cryptographically broken and should not be used for security-critical applications. Use SHA-256 or higher instead.
