"Invalid Encoding"

This function const decryptedMessege = decryptSafely({ encryptedData: {ciphertext: validator.data, version:"x25519-xsalsa20-poly1305", ephemPublicKey:validator.publicKey, nonce:"XUYgP2Bgtr4CPZVxTCPzKdSaTyMV7JzUkH7a5msSXxs="}, privateKey: validator.privateKey })

Leads to an “invalid encoding” error. I tracked it down to this piece of code:

function validateBase64(s) { if (!(/^(?:[A-Za-z0-9+\/]{2}[A-Za-z0-9+\/]{2})*(?:[A-Za-z0-9+\/]{2}==|[A-Za-z0-9+\/]{3}=)?$/.test(s))) { throw new TypeError('invalid encoding'); } }

And this appears to happen when s=validator.pubilcKey. That is to say, MetaMask public keys such as my own “0x3b89aC05D2d53f3775697B5Dbc75d8852E740403” is not valid according to the regex. If I remove the “0x” at the start it works but I instead get “bad public key size” error instead. So I don’t know what to do here.

According to the documentation for nacl.box.open, it will return null if authentication fails: https://github.com/dchest/tweetnacl-js#naclboxopenbox-nonce-theirpublickey-mysecretkey. So something must be wrong with either the public key or private key.

Closing as it doesn’t appear that this is due to a bug. Feel free to continue asking for help in this thread and we’ll help if we get time.
