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
Enter your password or text to hash.
- 2
Select hash algorithm (SHA-256, SHA-512, or SHA-1).
- 3
Click "Generate Hash" to create the hash.
- 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.
