Privacy & Security
All hash calculations are performed locally in your browser using the CryptoJS library. No data is transmitted to any server. Your files and text never leave your device.
Security Recommendations
- •For security-critical applications, use SHA-256 or SHA-512
- •MD5 and SHA-1 are considered cryptographically broken
- •Use HMAC for message authentication and API signing
- •Never use hashing alone for password storage - use bcrypt, scrypt, or Argon2
