attested-fetch (archived)

An experimental tool for fetching content from an HTTPS URL within an SGX enclave. The output is a JSON file containing SGX evidence and the HTTPS response.

An example implementation could be seen in scitt-ccf-ledger prior to the removal of did:web issuer verification.

Getting started

./build.sh
./test.sh

Run manually:

dist/afetch dist/libafetch.enclave.so out.json https://github.com nonce42

Virtual mode

In addition to the normal mode of usage described above, attested fetch may be used in a "virtual mode". In this mode, no SGX enclave is used. This can be useful for development, but provides no verifiable security guarantees about its output.

Virtual mode can be enabled by setting the PLATFORM variable:

export PLATFORM=virtual
./build.sh
./test.sh
