 Takes an address of either upper or lower case, with or without a hex prefix, and returns an all-lowercase, hex-prefixed address, suitable for submitting to an ethereum provider.
+
+### personalSign (privateKeyBuffer, msgParams)
+
+msgParams should have a `data` key that is hex-encoded data to sign.
+
+Returns the prefixed signature expected for calls to `eth.personalSign`.
+
+### recoverPersonalSignature (msgParams)
+
+msgParams should have a `data` key that is hex-encoded data unsigned, and a `sig` key that is hex-encoded and already signed.
+
+Returns a hex-encoded sender address.
