tests/basic_integration/lib/prebuild.sh (1)
3-3: LGTM, but consider addressing warnings and adding documentation.The change from
test_encryptortofake_encryptaligns with the PR objectives, particularly the updates to tests and mocks. However, there are a couple of suggestions to improve the script:
Reconsider using
RUSTFLAGS="-A warnings". Suppressing all warnings might hide potential issues. Consider removing this flag or using more specific warning suppressions if absolutely necessary.Add a comment explaining the purpose of
fake_encryptand why it replacedtest_encryptor. This would improve code documentation and make it easier for other developers to understand the change.Consider applying these changes:
#!/usr/bin/env sh -cd packages/ciphernode && RUSTFLAGS="-A warnings" cargo build --bin fake_encrypt --bin node --bin aggregator; +# Change to the ciphernode package directory +cd packages/ciphernode + +# Build the required binaries +# fake_encrypt: [Add a brief description of its purpose] +# node: [Add a brief description of its purpose] +# aggregator: [Add a brief description of its purpose] +cargo build --bin fake_encrypt --bin node --bin aggregatorThis change removes the warning suppression and adds explanatory comments, improving code clarity and potentially catching important warnings during the build process.
packages/evm/contracts/test/MockE3Program.sol (1)
23-26: Good use of abi.decode, consider adding a commentThe replacement of inline assembly with
abi.decodeimproves readability and safety. This is a positive change.Consider adding a brief comment explaining the structure of
e3ProgramParamsfor better clarity:+ // e3ProgramParams contains (bytes, IInputValidator) (, inputValidator) = abi.decode( e3ProgramParams, (bytes, IInputValidator) );packages/ciphernode/enclave_node/src/bin/pack_e3_params.rs (3)
6-9: LGTM: Robust hex parsing function.The
parse_hexfunction correctly handles both "0x" prefixed and non-prefixed hex strings, returning a Result for proper error handling.Consider adding a check for empty strings to provide a more specific error message:
fn parse_hex(arg: &str) -> Result<u64, ParseIntError> { + if arg.trim().is_empty() { + return Err(ParseIntError::new()); + } let without_prefix = arg.trim_start_matches("0x"); u64::from_str_radix(without_prefix, 16) }
11-28: LGTM: Well-structured CLI argument definition.The
Argsstruct effectively defines the command-line interface for the utility, with appropriate types and help messages for each field.Consider adding input validation for the
degreeandplaintext_modulusfields to ensure they are within acceptable ranges. You can use thevalue_parserattribute with a custom validation function:fn validate_degree(s: &str) -> Result<u64, String> { let degree: u64 = s.parse().map_err(|_| format!("`{}` isn't a valid degree", s))?; if degree.is_power_of_two() && degree >= 1024 && degree <= 32768 { Ok(degree) } else { Err(format!("Degree must be a power of 2 between 1024 and 32768")) } } #[arg(short, long, value_parser = validate_degree)] degree: u64,Apply similar validation for
plaintext_modulusbased on your specific requirements.
30-45: LGTM: Main function implements the core utility logic effectively.The
mainfunction correctly parses arguments, performs basic validation, encodes parameters, and outputs the result.Consider the following improvements:
- Use
eprintln!for error messages to separate them from the main output:- println!("Parameter `--moduli` must include at least one value"); + eprintln!("Error: Parameter `--moduli` must include at least one value");
- Handle the
no_crpflag in the encoding process:- let encoded = encode_bfv_params(args.moduli, args.degree, args.plaintext_modulus); + let encoded = encode_bfv_params(args.moduli, args.degree, args.plaintext_modulus, !args.no_crp);
- Use
alloy::hex::encodefor consistent hex encoding:- for byte in abi_encoded { - print!("{:02x}", byte); - } + println!("{}", alloy::hex::encode(abi_encoded));These changes will improve error visibility, respect the
no_crpflag, and use a consistent hex encoding method.packages/ciphernode/core/src/utils.rs (2)
48-50: New function for encoding BFV parameters looks good.The
encode_bfv_paramsfunction provides a convenient way to encode BFV parameters and reuses the existingsetup_bfv_paramsfunction, which is good for code maintainability.Consider using
usizefor thedegreeparameter instead ofu64to avoid the cast:-pub fn encode_bfv_params(moduli: Vec<u64>, degree: u64, plaintext_modulus: u64) -> Vec<u8> { - setup_bfv_params(&moduli, degree as usize, plaintext_modulus).to_bytes() +pub fn encode_bfv_params(moduli: Vec<u64>, degree: usize, plaintext_modulus: u64) -> Vec<u8> { + setup_bfv_params(&moduli, degree, plaintext_modulus).to_bytes()This change would make the function signature more consistent with
setup_bfv_paramsand eliminate the need for the cast.
52-56: New function for decoding BFV parameters is well-implemented.The
decode_paramsfunction effectively deserializes BFV parameters from bytes, with good error handling usinganyhow::Context. The use ofArcfor wrapping the result is appropriate for efficient sharing of the deserialized parameters.For consistency with the
encode_bfv_paramsfunction, consider renaming this function todecode_bfv_params:-pub fn decode_params(bytes: &[u8]) -> Result<Arc<BfvParameters>> { +pub fn decode_bfv_params(bytes: &[u8]) -> Result<Arc<BfvParameters>> { Ok(Arc::new( BfvParameters::try_deserialize(bytes).context("Could not decode Bfv Params")?, )) }This change would make the function naming more consistent across the module.
packages/ciphernode/core/src/main_aggregator.rs (1)
46-50: Approve RNG creation changes with a suggestion for error handlingThe changes to RNG creation look good. Using
OsRngdirectly is a more straightforward approach. However, consider handling the potential failure of RNG creation more gracefully.Consider replacing the
expectcall with proper error handling:let rng = Arc::new(Mutex::new( rand_chacha::ChaCha20Rng::from_rng(OsRng).map_err(|e| { // Log the error log::error!("Failed to create RNG: {}", e); // Return a custom error or propagate this error YourCustomError::RngCreationFailed(e) })? ));This approach would allow for better error reporting and prevent a potential panic.
packages/ciphernode/core/src/sortition.rs (1)
41-43: LGTM:SortitionModuleimplementation updated correctlyThe
containsmethod implementation inSortitionModulehas been successfully updated to use theSeedtype. The addition of.into()when passingseedtoDistanceSortition::newensures compatibility with the existing implementation.Consider caching the result of
seed.into()if it's used multiple times within the method to avoid repeated conversions:let seed_value = seed.into(); DistanceSortition::new( seed_value, // ... rest of the code )This minor optimization could be beneficial if the conversion is computationally expensive or if the method is called frequently.
packages/ciphernode/core/src/plaintext_aggregator.rs (1)
Line range hint
108-186: LGTM:Handler<DecryptionshareCreated>implementation updated.The implementation correctly uses the
seedvariable of typeSeedin the context of theGetHasNodemessage. This is consistent with the earlier changes to thePlaintextAggregatorStateand constructor.Consider adding a type annotation for
seedwhen destructuringPlaintextAggregatorState::Collectingfor improved readability:- threshold_m, seed, .. + threshold_m, seed: Seed, ..This change would make the type of
seedexplicit at the point of use.packages/ciphernode/core/src/keyshare.rs (2)
58-62: Address the TODO comments related to key encryption and decryption.The TODO comments indicate pending implementation for decrypting from the FHE actor and re-encrypting the secret key securely. These are crucial for maintaining the security and functionality of the system.
Would you like assistance in implementing the key encryption and decryption logic? I can help by providing code examples or outlining best practices for secure key management.
119-119: Remove unnecessary debug statements.The
println!("\n\nDECRYPTING!\n\n");statement may clutter the output in a production environment.Consider removing or replacing it with proper logging if necessary.
-println!("\n\nDECRYPTING!\n\n");packages/ciphernode/core/src/evm_enclave.rs (1)
Line range hint
96-98: Handle potential errors without usingunwrap()Using
unwrap()on asynchronous operations can cause the program to panic if an error occurs. It's better to handle these potential errors gracefully to improve the robustness of the code.Consider propagating the errors using the
?operator and adjusting the function signature to return aResult:-pub async fn connect_evm_enclave(bus: Addr<EventBus>, rpc_url: &str, contract_address: Address) { +pub async fn connect_evm_enclave(bus: Addr<EventBus>, rpc_url: &str, contract_address: Address) -> Result<()> { let evm_manager = EvmContractManager::attach(bus.clone(), rpc_url).await; let evm_listener = evm_manager .send(AddListener { contract_address }) .await - .unwrap(); + ?; evm_listener .send(AddEventHandler::<E3Requested>::new()) .await - .unwrap(); + ?; evm_listener .send(AddEventHandler::<CiphertextOutputPublished>::new()) .await - .unwrap(); + ?; evm_listener.do_send(StartListening); println!("Evm is listening to {}", contract_address); + Ok(()) }This change ensures that any errors encountered during the asynchronous calls are properly propagated to the caller for handling.

18-18: Convert inline comment to a TODO for clarityThe comment on line 18 suggests a potential enhancement. Converting it to a TODO comment will make the intended action clearer and help in tracking it.
Apply this diff:
-# We _may_ wish to get these off the hardhat environment somehow? +# TODO: Retrieve these contract addresses from the hardhat environment
21-21: Add descriptive comment forINPUT_VALIDATOR_CONTRACTProviding context for the
INPUT_VALIDATOR_CONTRACTenvironment variable will improve readability and maintainability.Consider adding a comment:
+# Address of the input validator contract export INPUT_VALIDATOR_CONTRACT="0x8A791620dd6260079BF849Dc5567aDC3F2FdC318"packages/ciphernode/core/src/events.rs (2)
388-394: Use consistent casing for enum variants to follow Rust conventions.Consider renaming the enum variants to use
UpperCamelCasefor better readability and to align with Rust naming conventions. For example, renamePublickeyAggregationtoPublicKeyAggregation, andIOtoIo.Apply this diff to rename the variants:
pub enum EnclaveErrorType { - Evm, - KeyGeneration, - PublickeyAggregation, - IO, - PlaintextAggregation, - Decryption, + Evm, + KeyGeneration, + PublicKeyAggregation, + Io, + PlaintextAggregation, + Decryption, }
256-263: Avoid unnecessary cloning to improve performance.In the
From<EnclaveError> for EnclaveEventimplementation, cloningdatamay be unnecessary if ownership can be transferred. Consider removing the clones to enhance efficiency.Apply this diff to eliminate unnecessary clones:
impl From<EnclaveError> for EnclaveEvent { fn from(data: EnclaveError) -> Self { EnclaveEvent::EnclaveError { - id: EventId::from(data.clone()), - data: data.clone(), + id: EventId::from(&data), + data, } } }

tests/basic_integration/output/.gitignore (1)
3-3: LGTM: Addition of*.hexto .gitignore is appropriate.The inclusion of
*.hexin the .gitignore file is a good practice. It ensures that hexadecimal output files, which are likely generated during the testing process, are not tracked by version control. This aligns well with the existing entries and the overall purpose of the .gitignore file in this directory.To ensure we're not missing any other file types that might need to be ignored, let's check the output directory for any other file extensions:
tests/basic_integration/lib/pack_e3_params.sh (2)
1-1: LGTM: Correct shebang for a bash script.The shebang line is correctly written, using the portable
/usr/bin/env bashapproach.
3-3: 🛠️ Refactor suggestionConsider improving script robustness and readability.
The script successfully changes directory, sets RUSTFLAGS, and runs the Rust binary. However, there are a few points to consider:
Error handling: The script doesn't handle potential errors if the directory change fails. Consider adding error checking.
Readability: The line is quite long. Consider breaking it into multiple lines for better readability.
Warning suppression: Suppressing all warnings with
-A warningsmight hide important information. Is this intentional for all use cases of this script?Here's a suggested refactor for improved robustness and readability:
-cd packages/ciphernode && RUSTFLAGS="-A warnings" cargo run --bin pack_e3_params -- "$@" +#!/usr/bin/env bash + +set -e # Exit immediately if a command exits with a non-zero status + +cd packages/ciphernode || exit 1 + +RUSTFLAGS="-A warnings" cargo run --bin pack_e3_params -- "$@"Could you clarify the intended use of this script and whether suppressing all warnings is necessary? This will help determine if additional modifications are needed.

FromErrortrait cautiously to avoid conflicts with existing traits or future standard library additions. Verify that this trait name does not clash with other commonly used traits and consider using a more descriptive name if necessary.Run the following script to check for existing traits named
FromError:#!/bin/bash # Description: Check for existing 'FromError' trait definitions in the codebase or dependencies. # Search for trait definitions named 'FromError'. rg --type rust 'trait FromError' -A 2
307-308: Verify consistency of theSeedtype usage across the codebase.The
E3Requestedstruct now includespub seed: Seed. Ensure that all instances whereE3Requestedis constructed or used have been updated to accommodate this change, preventing potential type mismatches or runtime errors.Run the following script to check for usages of
E3Requestedand verify theseedfield handling:packages/ciphernode/core/src/lib.rs (9)
37-37: Ensure new public functions are documented and testedThe functions
decode_e3_paramsandencode_e3_paramsare now being publicly exported. Please ensure they are adequately documented and covered by unit tests to maintain code quality and API usability.
97-97: Optimize RNG handling by passing without cloningPassing
rngdirectly toFheFactory::create(rng)avoids unnecessary cloning of the random number generator, which can improve performance and reduce overhead.
109-109: Enhance logging withSimpleLoggerattachmentAttaching
SimpleLoggerusingSimpleLogger::attach(addr, bus.clone())will improve logging capabilities during the setup of the local cipher node, aiding in debugging and monitoring.
127-127: Verify secure handling of encapsulated seedBy encapsulating the seed within the
Seedstruct, make sure that it maintains the desired level of randomness and that the seed is securely managed to prevent potential security vulnerabilities.
145-147: Ensure thread-safe initialization of RNG with mutexInitializing
ChaCha20RngusingArc::new(std::sync::Mutex::new(...))requires careful handling to avoid deadlocks and ensure thread safety. Verify that the mutex is properly managed in concurrent environments.
210-211: Duplicate issue: Exposing seed in eventsThis duplicates the earlier concern about including
seedin events. Ensure that all instances where the seed is used in events are reviewed for security implications.
373-374: Maintain consistency in seed usage within testsThe seed initialization in
test_p2p_actor_forwards_events_to_busmirrors previous changes. Confirm that this maintains test integrity and aligns with the updatedSeedstruct usage.
385-386: Duplicate issue: Exposing seed in eventsAs previously noted, including
seedin event payloads may introduce security vulnerabilities. Re-evaluate its necessity in this context.
177-178:⚠️ Potential issuePotential security concern: Exposing seed in events
Including
seedin theE3Requestedevent may expose sensitive information. Assess whether the seed should be transmitted in clear text or if it needs to be protected to prevent security risks like replay attacks.⛔ Skipped due to learnings

83-84: Ensure correct encoding ofe3ProgramParamsThe
e3ProgramParamsnow include bothbytesandaddresstypes. Verify that"0x12345678"correctly represents the expectedbytesdata for the E3 Program, and that theinputValidatoraddress is accurately retrieved usingawait inputValidator.getAddress().
536-536: Verify the use ofZeroHashandethers.ZeroAddressin testsIn this test case,
e3ProgramParamsare encoded with[ZeroHash, ethers.ZeroAddress]. Ensure that usingZeroHashandethers.ZeroAddressaccurately simulates the scenario where the encryption scheme is disabled, and that it triggers the expectedInvalidEncryptionSchemeerror.
554-554: Test correctly simulates an invalid computation requestBy encoding
e3ProgramParamswith[ZeroHash, ethers.ZeroAddress], the test effectively simulates an invalid request. This setup correctly triggers theInvalidComputationRequesterror as expected.
