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
