Function tss_sapi::utils::open_context_from_env [−] [src]

pub fn open_context_from_env() -> Result<Context>

Open a Context over a socket or the raw device based on the environment.

The TPM2 tools project relies on several environment variables to determine how to open the TPM2 context. If the environment variable TPM2TOOLS_TCTI_NAME is not present or has the value of "device" set, then a context is created pointing at a local device, with the device name pulled from the TPM2TOOLS_DEVICE_FILE environment variable.

If TPM2TOOLS_TCTI_NAME has the value "socket" set, then a context is created using a socket. The TPM2TOOLS_SOCKET_ADDRESS environment variable specifies the host to connect to and must be present. The TPM2TOOLS_SOCKET_PORT environment variable specifies the port to connect to and is optional.

Examples

use tss_sapi::utils;

let context = utils::open_context_from_env()?;
