🔐 Hash Security Information

Algorithm Recommendations

• SHA-256: Recommended for most use cases
• SHA-512: Highest security, larger output
• MD5/SHA-1: Not recommended for security
• SHA-224/384: Good alternatives

Security Best Practices

• Use SHA-256 or SHA-512 for security-critical applications
• Combine with salt for password hashing
• Verify hashes using multiple sources
• Consider using HMAC for message authentication
