Ethereum: Web3.Py and the supplier of the supplier of supplier (HSM)
The increase in decentralized applications (DAPP) and blockchain -based services led to an increasing need for robust safety measures, in particular with regard to the signing of transactions. In this article, we will explore the use of hardware safety modules (HSMS) from different cloud service providers, such as Google Cloud on web3.py, to protect Ethereum transactions.
What are the material safety modules (HSMS)?
Hardware safety modules (HSMS) are specialized hardware devices designed to provide a safe environment to store and manage confidential data. They use advanced cryptographic algorithms and mechanisms to protect data from unauthorized access, falsification or engagement. HSMs are generally used in corporate environments, but can also be used in other sectors that require robust security.
** Why use the Cloud hardware safety modules (HSMS) with web3.py?
The use of the HSM of a web cloud supplier. Py offers several advantages:
- Centralized management : Cloud suppliers offer a centralized management system, facilitating the management and monitoring of various HSM bodies.
- Evolution : Cloud suppliers can evolve their infrastructure to meet large -scale application requests like Ethereum.
3 and 3
- Safety updates
: Cloud suppliers generally provide updates and safety fixes, ensuring that HSM instances are safe and updated.
Use of the Google Cloud equipment safety module (HSM)
Google Cloud offers an HSM service called Cloud HSM, which provides a safe environment to store and manage confidential data. To use Cloud HSM with web3.py, you can follow these steps:
- Create a new HSM instance: Start a new body of the HSM Cloud service and configure it according to your requirements.
- Configure the Ethereum customer library: Use the web3.py library to connect to your Ethereum node using the HSM Cloud public key to sign transactions.
- Use the
HSMweb3.pyfunction: Once connected, use the" HSM "function of the web3.py library to sign Ethereum transactions.
Here is an example of code of code:
Python
Import web3
Create a new HSM body
from google.cloud import hsm_v1beta1 as hsm_v1beta1
From Google.oauth2 Import Service_account
Configure the HSM cloud instance
CREDINTS = service_account.credentials.from_service_account_file (
'Path/to/your/service_account_key.json', scopes = ['
))
Create a new HSM client
hsm_client = hsm_v1beta1.hsmclient (indenge = ideal, project_id = 'Your_Project_id')
Connect to the Ethereum node using the HSM Cloud public key to sign transactions
W3 = web3.web3 (hsm_client)
Use theweb3.py function to sign Ethereum transactions
Def sign_transaction (transaction):
Signed_transation = w3.eth.account.sign_transaction (
transaction,
w3.eth.abi ['eth_sendransaction'],
Signature_type = 'reversed',
public_key = hsm_client.public_key
))
Back w3.eth.send_raw_transaction (signed_transation.rawtransaction)
Example of use:
Transaction = {'of': '0x ...', 'to': '0x ...', 'Value': 1.0}
Signed_transaction = sign_transaction (transaction)
` ‘
Conclusion
The use of hardware safety modules from different cloud service providers, such as Google Cloud on Web3.Py, offers a robust and safe means of signing Ethereum transactions. By taking advantage of centralized management, scalability, reliability and security features provided by cloud suppliers, you can guarantee the confidentiality, integrity and authenticity of your transactions.
