How to Hash a Password or String Online
Generate cryptographic hashes from text or files locally in your browser. Supports SHA-256, SHA-512, and MD5.
Hashing is a one-way function that converts any input to a fixed-length string. It's used for verifying file integrity, storing passwords (with salt), and data fingerprinting.

- 💡Never store passwords as plain MD5 or SHA-256 — use bcrypt or Argon2 with salt for proper password storage
- 💡Use SHA-256 or SHA-512 for file integrity; MD5 is deprecated for security purposes
Frequently Asked Questions
Is SHA-256 safe for password storage?
No. SHA-256 is too fast — attackers can compute billions per second. Use bcrypt, scrypt, or Argon2 which are designed for password storage with built-in work factors.
