Functions

def create(model: str = 'meta-llama/Llama-2-70b-chat-hf', prompt: str = '', temperature: float = 0.7, verbose: bool = False) ‑> str

Start a prediction.

Args

model (str, default = "meta-llama/Llama-2-70b-chat-hf"): The model on which you want to run a prediction on.
prompt : str
The prompt on which you want to run a prediction on.
temperature : float, default = 0.7
The temperature requested (default to 0.7).
verbose : bool, default = False
Allows to print all details of the verification process.

Returns

str
The result of the prediction made by the server

Classes

class Client (verbose: bool = False)

A class to represent a connection to a BlindLlama server.

Init the Client class.

Args

verbose : bool, default = False
Allows to print all details of the verification process.

Returns

Client
Client object.

Methods

def predict(self, prompt: str, temperature: float = 0.7) ‑> str

Start a prediction.

Args

prompt : str
The prompt on which you want to run a prediction on.
temperature : float, default = 0.7
The temperature requested.

Returns

str
The result of the prediction made by the server
def verify_build_response(self, build_response: bytes, ca_cert='', expected_pcr='')

Verify received attesation validity

  1. Parse the JSON reponse
  2. Check simulation mode
  3. Verify certificate chain
  4. Verify quote signature
  5. Verify boot PCRs (firmware, bootloader, initramfs, OS)
  6. Verify event log (final hash in PCR_FOR_MEASUREMENT) by replaying it (works like a chain of hashes)
  7. Verify TLS certificate (final hash in PCR_FOR_CERTIFICATE)

Args

build_response : bytes
reponse of the attestation endpoint
verbose : bool, default = False
whether to print verification information in stdout
def verify_server_certificate(self, expected_pcr)

Retrieve server certificate and validate it with the attestation report.
