A geth node is managing an Ethereum account, having the control over its private key at keystore folder. I guess to keep it safe, best practices are letting geth by its own perform all operations that require access to the private key. Well, the case is I need to decrypt a message that was encrypted using the public key of the geth account, in order to be only readable by this account. So, is there any geth function via JSON-RPC capable of decrypting a message using the private key of the account? Something like this:
ECIES.Decrypt(account, message); The only other choice is left seems to be accessing directly to the keystore folder and decrypt the message using the private key there, but I don't feel comfortable doing so, it seems a quite insecure scheme, right?
