Examples
Simple Text
Input: Hello World
MD5: b10a8db164e0754105b7a99be72e3fe5
SHA-256: a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e
Password
Configuration
Input: {"api_key": "secret", "timestamp": "2024-01-01"}
SHA-256: 8f7d3b2a1e9c6f5d4a3b2c1d0e9f8a7b6c5d4e3f2a1b0c9d8e7f6a5b4c3d2e1f0
Security Notes
- MD5/SHA-1: Not suitable for security-critical applications
- SHA-256+: Recommended for modern applications
- Salt: Always use salt for password hashing
- Collision Resistance: SHA-256+ provides strong collision resistance
