7add64562e feat: Simplify asymmetric encryption/decryption
Some checks are pending
Rhai Tests / Run Rhai Tests (pull_request) Waiting to run
Details 
- Simplify asymmetric encryption by using a single symmetric key
  instead of deriving a key from an ephemeral key exchange.  This
  improves clarity and reduces complexity.
- The new implementation encrypts the symmetric key with the
  recipient's public key and then encrypts the message with the
  symmetric key.
- Improve test coverage for asymmetric encryption/decryption.

25f2ae6fa9 refactor: Refactor keypair and Ethereum wallet handling
Some checks are pending
Rhai Tests / Run Rhai Tests (push) Waiting to run
Details 
- Moved `prepare_function_arguments` and `convert_token_to_rhai` to the `ethereum` module for better organization.
- Updated `keypair` module to use the new `session_manager` structure improving code clarity.
- Changed `KeyPair` type usage to new `vault::keyspace::keypair_types::KeyPair` for consistency.
- Improved error handling and clarity in `EthereumWallet` methods.

Each network has its own configuration, including:
## Wallet Address Consistency
In the new design, Ethereum wallet addresses are consistent across all EVM-compatible networks. This reflects how Ethereum addresses work in reality - the same private key generates the same address on all EVM chains.
```rust
// Create a wallet once
let wallet = create_ethereum_wallet()?;
// Use the same wallet address on any network
let eth_balance = get_balance("Ethereum", wallet.address).await?;
let polygon_balance = get_balance("Polygon", wallet.address).await?;
let gnosis_balance = get_balance("Gnosis", wallet.address).await?;
```
- RPC URL
- Chain ID
- Explorer URL
- Native currency symbol and decimals
## Error Handling
@ -184,42 +149,12 @@ The module uses the `CryptoError` type for handling errors that can occur during
- `InvalidAddress` - Invalid Ethereum address format
- `ContractError` - Smart contract interaction error
- `NoKeypairSelected` - No keypair selected for wallet creation
- `InvalidKeyLength` - Invalid private key length
## Examples
For examples of how to use the Ethereum module, see the `examples/vault` directory, particularly:
For examples of how to use the Ethereum module, see the `examples/hero_vault` directory, particularly:
- `contract_example.rhai` - Demonstrates loading a contract ABI and interacting with smart contracts
- `agung_simple_transfer.rhai` - Shows how to perform a simple ETH transfer on the Agung network
- `agung_send_transaction.rhai` - Demonstrates sending transactions on the Agung network
- `agung_contract_with_args.rhai` - Shows how to interact with contracts with arguments on Agung
## Adding a New Network
With the new design, adding a new network is as simple as registering it with the network registry:
```rust
// In Rust
ethereum::register_network(
"Optimism",
10,
"https://mainnet.optimism.io",
"https://optimistic.etherscan.io",
"ETH",
18
);
// In Rhai
register_network(
"Optimism",
10,
"https://mainnet.optimism.io",
"https://optimistic.etherscan.io",
"ETH",
18
);
```
No code changes are required to add support for new networks!

# Keyspace Module Specification
This document explains the purpose and functionality of the `keyspace` module within the Hero Vault.
## Purpose of the Module
The `keyspace` module provides a secure and organized way to manage cryptographic keypairs. It allows for the creation, storage, loading, and utilization of keypairs within designated containers called keyspaces. This module is essential for handling sensitive cryptographic material securely.
## What is a Keyspace?
A keyspace is a logical container designed to hold multiple cryptographic keypairs. It is represented by the `KeySpace` struct in the code. Keyspaces can be encrypted and persisted to disk, providing a secure method for storing collections of keypairs. Each keyspace is identified by a unique name.
## What is a Keypair?
A keypair, represented by the `KeyPair` struct, is a fundamental cryptographic element consisting of a mathematically linked pair of keys: a public key and a private key. In this module, ECDSA (Elliptic Curve Digital Signature Algorithm) keypairs are used.
* **Private Key:** This key is kept secret and is used for operations like signing data or decrypting messages intended for the keypair's owner.
* **Public Key:** This key can be shared openly and is used to verify signatures created by the corresponding private key or to encrypt messages that can only be decrypted by the private key.
## How Many Keypairs Per Space?
A keyspace can hold multiple keypairs. The `KeySpace` struct uses a `HashMap` to store keypairs, where each keypair is associated with a unique string name. There is no inherent, fixed limit on the number of keypairs a keyspace can contain, beyond the practical limitations of system memory.
## How Do We Load Them?
Keyspaces are loaded from persistent storage (disk) using the `KeySpace::load` function, which requires the keyspace name and a password for decryption. Once a `KeySpace` object is loaded into memory, it can be set as the currently active keyspace for the session using the `session_manager::set_current_space` function. Individual keypairs within the loaded keyspace are then accessed by their names using functions like `session_manager::select_keypair` and `session_manager::get_selected_keypair`.
## What Do They Do?
Keypairs within a keyspace are used to perform various cryptographic operations. The `KeyPair` struct provides methods for:
* **Digital Signatures:** Signing messages with the private key (`KeyPair::sign`) and verifying those signatures with the public key (`KeyPair::verify`).
* **Ethereum Address Derivation:** Generating an Ethereum address from the public key (`KeyPair::to_ethereum_address`).
* **Asymmetric Encryption/Decryption:** Encrypting data using a recipient's public key (`KeyPair::encrypt_asymmetric`) and decrypting data encrypted with the keypair's public key using the private key (`KeyPair::decrypt_asymmetric`).
The `session_manager` module provides functions that utilize the currently selected keypair to perform these operations within the context of the active session.
