I can provide an article on how to use the MetamSK eth_GencritctionPublickey function to encrypt data files before loading them on IPFS.
Metamk encryption data: use of eth_Gencrinspublickey
In this article, we will explore how to use the Metamask eth_Gencritctionpublickey function to encrypt data files before loading them on IPFS. This is a useful feature that allows you to ensure your local storage and avoid unauthorized access.
What is Eth_Gencrintionpublickey?
Eth_Gencripenspublickey is a metamask function that recovers the public key of an Ethereum account. In this case, we will use it to recover the public key of the owner of our IPFS container.
METAMASK configuration
To use eth_Gencritctionpublickey, you must have MetamSk installed and configured on your device. Here are the steps:
- Download and install MetamSk from the official website: <
- Start metamask on your device.
- Connect your Ethereum wallet.
Use of Eth_Gencrintionpublickey
Once Metamask has configured, you can use eth_Gencritctionpublickey to recover the public key of the owner of its IPFs container:
`JavaScript
const metamask = require ('metamask');
// Establish the Ethereum address of its IPFS container
constorDddress container = '0x ...';
// Establish the metamash wallet id
Const Balletidos = '0x ...';
// Obtain the public key using the eth_gencryptationpublickey function
const publickey = arat metamSk.Gencripenspublickey (containeraddress, walletid);
Console.log ('Public Key:', Public Key);
Encryption data
To encrypt data files before loading them on IPFS, you can use a library like 'buffer and’ cryptoon node.js:
JavaScript
const buffer = require ('buffer');
const crypto = request ('crypt');
// Read the content of the file
Const Filecontes = Fs.readfilesync ('Path/To/File.txt', 'UTF8');
// Create a new instance of AES-GCM encryption with a Metamask Public Key Key
Const IV = Crypto.randombytes (16);
const cipher = crypto.createcipheriv ('AES-256-gcm', buffer.from (publickey, 'hex'), IV);
// Cifre the content of the file
Const encryptedfilecontes = alea cipher.update (Filecontents);
Cencedfilecontents = buffer.concat ([Cicypedfilecontes, iv]);
const encumbodata = alea cipher.final ();
Console.log ('encrypted data:', encryption.tostring ());
Save encrypted data
To save the encrypted data in a new file on your device:
JavaScript
fs.writefilesync ('path/to/cicrypted/file.txt', Cicypteddata);
Conclusion
In this article, we explore how to use theeth_gencrypitionskeyfunction in Metamask to recover the public key from an Ethereum account and then encrypt data files before loading them to IPFS. This feature provides a safe way to protect your local storage and avoid unauthorized access.
Note: Make sure Metamask has installed and configured on your device, and that the container address is correctly specified in theeth_gencryptionspublickey` function.
