# Teaclave Command Line Tool

The Teaclave command line tool (teaclave_cli) provides utilities to interactive with the platform. The command line tool has several sub-commands:

  • encrypt/decrypt: These two subcommands are to encrypt/decrypt data used on the platform. Supported algorithms include AES-GCM (128bit and 256 bit), and Teaclave File (128bit).
  • verify: Verify the signatures of the enclave info (which contains MRSIGNER and MRENCLAVE) signed by auditors with their public keys. The enclave info is used for remote attestation, Please verify it before connecting the platform with the client SDK.

# Encrypt/Decrypt

Here are two examples to encrypt and decrypt files with the CLI.

$ ./teaclave_cli encrypt \
    --algorithm teaclave-file-128 \
    --key 00000000000000000000000000FF1234 \
    --input-file ${FILE} \
    --output-file ${ENCRYPTED_FILE} \

$ ./teaclave_cli decrypt \
    --algorithm teaclave-file-128 \
    --key 00000000000000000000000000FF1234 \
    --input-file ${ENCRYPTED_FILE} \
    --output-file ${DECRYPTED_FILE}

# Verify

Here is an example to verify auditors' signatures of the enclave info file.

$ ./teaclave_cli verify \
    --enclave-info ../examples/enclave_info.toml \
    --public-keys $(find ../examples -name "*.public.pem") \
    --signatures $(find ../examples -name "*.sign.sha256")
Verify successfully.
