## What it is
Open Enclave SDK is a hardware-agnostic open source SDK for building C and C++ applications that use hardware-based Trusted Execution Environments (TEEs). It provides a unified API across enclave technologies such as Intel SGX and ARM TrustZone (OP-TEE), spanning cloud to edge on Linux and Windows.

## Use cases
- build confidential computing applications that protect data in use
- develop enclave applications for Intel SGX
- port enclave code across TEE hardware vendors
- run trusted code in a protected memory region on cloud or edge
- partition an application into trusted enclave and untrusted host components

## When to choose
- you need a vendor-neutral, unified API for enclave development across SGX and TrustZone
- you are writing C/C++ confidential computing apps for Linux or Windows
- you want an open source, MIT-licensed alternative to vendor-specific enclave SDKs

## When to avoid
- you need enclave support for TEEs or platforms not covered by the SDK
- your project uses languages other than C/C++
- you need a fully maintained SDK with broad community support rather than a project in maintenance mode

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, security, cryptography
- domain: security, cloud-computing, developer-tools
- platform: windows, cpp, c
- tags: confidential-computing, trusted-execution-environment, enclave, intel-sgx, tee, hardware-security, linux
