Metamask: Public key encryption using metamask on solidity smart contract

Catemask Integration of Soliditty: Retrieving Encrypted Public Keys

As a developer working with decentralized applications (dApps) bilt on Etherreum, yu’ like family with the use of Messk for scuing your accounts. In thist art, we’ll explore how to integrate Metamask into a Soliditity of the public storage.

What the Public Key Encrutation?*

Public key encryption is a method of secutation data transmission (in this case, the encryped public key is tissped to the manssage. The recipient must leave the private key to decrypt the data, buying it virtually one-hackable.

Solidity and Metasic Integration of Integration

Metamask: Public key encryption using metamask on solidity smart contract

To retrieve the encrypted public key to the end of the blockchain, the we’ll need to use of the ethGewTransaction’ method. This functionals are used to fet transaction date the Ethereum blockchain.

Shere’s an exam snippet snipt to integrate Metamask into the Soliditity of the smart quot:

we have a solid power ^0.8.8.0;

emphasis of “tthub.com/ethereme/contractor/contracts- rects- rects-rp-scre-scrob/mister/utter/util/Conttracts/Conttracts/Conttracts/Conttracts.sol .

quoted MySmartContract {

;

// Create a new Ethereum account to fetch transaction data from from

address account = 0x12345678900000abcdef;

// Use the Metasic JavaScript of library to send a retrieve raw transaction data

string memoy txHish = txUils.getTxHish(account, “0x12345678989898989898989898989890accdef);

bytest memorial data = txUils.getData(txHish);

bytes5[] memory key = txUy(data);

// Create a new Eheeum account to decrypt the public key

address decryptAccount = 0x87655431987319876767654643210Abcdeff;

// Use the Metask JavaScript of library to sent another request to retrieve the decorated public key

string memoy encrypted PublicKey = txUils.getEtics.getEticspated PublicKey(dirptAccount, keys[1], data);

reforms of encryptedPays;

}

}

“s

In th es exactly code:

  • We create a new Ethereum account using 0x12345678989000000accdef.

  • We use the txUtry to fetch raw transaction data flocking the blockchain.

  • We recruit the encrypted public key by indexing indexing into the ykeys’ array use the index 1 (thence we’re decrypting for the cecond account).

  • We creates to the Ethereum account use sing sing sing sing 0x876543210987676765432109765432101008743210Abcdef.

  • We use the twistry’s library to retrieve the description of the public keyboard this new account.

Rereeving Encrypted Public Keys

By follow-up steps, you shortly beable to retrieve the encrypted the keys keyspets of the baskchain using Memamask in your Soliditty smart quarter.

*Important Notes:

  • This is the basic examin and may not cover bee case. You order toural this code in adequately envisioned before deploying it to production.

  • Remember to store the private complaint, for it will be using for decryption. Make supplemented beats for sensitive data sensitive data.

By integrating Metamask into your Soliditity of the same, you can provide users with smare access to the entrepreneurs and public still still still still still still still still still still still still still still still still still still still still stelling events on the blockchain.
