Ethers.js Version


Describe the Problem

I was trying to test the encrypt and decrypt feature of ethers.js with the public and private keys from the metamask wallet and built a really simple application that will retrieve the public key and encrypt the user's provided string, then decrypt the encrypted message to see if it will go back to the original message. When I clicked on "Decrypt" after initiating decryption, it throws the error saying the user is denying the decryption action. Screen recording attached.

The full code can be found here too: https://github.com/Eric1015/metamask-encrypt-file-example

Asked the same question here as well: https://github.com/ethers-io/ethers.js/issues/4139, also pending answers.

Code Snippet

Here is the code of how I am decrypting the message:

  const decryptMessage = useCallback(
    async (encryptedMessage: string) => {
      const { provider } = state;
      if (provider == null) return;
      const accounts: string[] = await provider.send('eth_requestAccounts', []);
      return await provider.send('eth_decrypt', [

The provider inside of the state is created in the following manner and stored as state:

      const { ethereum } = window;

      const provider = new ethers.BrowserProvider(ethereum);


Error: user rejected action (action="unknown", reason="rejected", info={ "error": { "code": -32603, "data": { "originalError": {  } }, "message": "MetaMask DecryptMessage: User denied message decryption." }, "payload": { "id": 9, "jsonrpc": "2.0", "method": "eth_decrypt", "params": [ "cynO2IeYe/weLFuV3/Ec2hhpxFFg5OU=", "<address>" ] } }, code=ACTION_REJECTED, version=6.5.1)

    No, on the Github side, there was a reply and he told me that this decrypt function of Metamask is gonna be deprecated, so I decided to seek for a different solution such as using the Lit protocol: developer.litprotocol.com
