Regarding the Myetherwallet reference: The JSON file you explained is usually a Keystore that is AES-encrypted, and Whatever you pasted tend to be the ciphertext and algorithm parameters which include salt and initialization vector (and all of which are have to decrypt, together with the password).
Also, in some networks for instance bitcoin, this kind of addresses should not be made use of Until sending nothing under your entire equilibrium, as The dearth of a return "alter" address may end up in a total loss of the primary difference (i.e. remaining volume not despatched) according to the software program utilized (and it is one more reason why Mind wallets are not extensively employed any longer).
