## What it is
Apache Teaclave SGX SDK (Rust SGX SDK) is a Rust-based software development kit for building Intel SGX enclave applications with memory safety. It provides a refactored, lightweight Rust port of Intel's SGX SDK with modern cargo-based build modes and support for common Rust crates like Tokio and Tonic inside enclaves.

## Use cases
- write intel sgx enclaves in rust
- build confidential computing applications
- develop privacy-preserving trusted applications
- run tokio and tonic inside sgx enclaves
- seal and encrypt data inside an enclave
- prototype sgx apps without sgx hardware using docker emulation

## When to choose
- you want memory-safe Rust development for Intel SGX enclaves
- you need to use standard Rust crates and async runtimes inside enclaves
- you want an actively maintained open-source alternative to Intel's C/C++ SGX SDK
- you want to prototype with prebuilt Docker images without TEE hardware

## When to avoid
- you target Arm TrustZone or OP-TEE instead of Intel SGX (use Teaclave TrustZone SDK)
- you need C/C++ enclave development
- your platform does not support Intel SGX
- you need a general-purpose confidential computing FaaS platform (the legacy Teaclave FaaS is no longer maintained)
