### 🛡️ Anonymization Strategies Explained
| Strategy | Description | Example | Use Case |
|----------|-------------|---------|----------|
| **replace** | Substitute with placeholders | `John Doe` → `` | General purpose, maintains structure |
| **redact** | Remove completely | `john@email.com` → `` | Maximum privacy, minimal data |
| **mask** | Hide with characters | `555-1234` → `***-****` | Partial visibility, format preserved |
| **hash** | Cryptographic hashing | `secret` → `2bb80d537b1da3e38bd30361aa855686bde0eacd7162fef6a25fe97bf527a25b` | Consistent anonymization, irreversible |
| **encrypt** | Reversible encryption | `data` → `encrypted_string` | Authorized access possible |
### 🌍 Supported Languages
