# Secure Query Processing

This how-to documentation group covers every step required for secure query processing: **encrypting input data**, **submitting queries** to models, **receiving encrypted results**, and **decrypting** the output. For deeper insight into the underlying FHE logic - such as key generation and encryption/decryption - visit our [GitHub repository](https://github.com/Lattica-ai/lattica_fhe_core).
