1# ALTS TSI Implementation
2 
3This directory contains an implementation of the Transport Security Interface (TSI) that uses Application Layer Transport Security (ALTS).

5## Overarching Purpose
6 
7This directory provides a concrete implementation of the TSI interfaces that can be used to secure gRPC connections with ALTS. ALTS is a mutual authentication and transport encryption system developed by Google.

11- **`crypt/`**: Contains code for performing cryptographic operations.
12- **`frame_protector/`**: Contains the implementation of the `tsi_frame_proteator` interface for ALTS.
13- **`handshaker/`**: Contains the implementation of the `tsi_handshaker` interface for ALTS.
14- **`zero_copy_frame_protector/`**: Contains an implementation of the `tsi_frame_protector` interface that avoids copying data.

16## Notes
17 
18- ALTS is a Google-specific security protocol.
19- It is designed to be efficient and to provide strong security for connections between services running within Google's infrastructure.
20- The ALTS TSI implementation is used by gRPC applications that need to communicate with other services that use ALTS.
