    byte is an alias for uint8, which means that a slice of uint8) (aka []uint8) is also a slice of byte (aka []byte).

    And byte slices and strings are directly convertible, due to the fact that strings are backed by byte slices:

    myByteSlice := []byte{ ... }     // same as myByteSlice := []uint8{ ... }
    myString := string(myByteSlice)  // myString is a string representation of the byte slice
    myOtherSlice := []byte(myString) // Converted back to byte slice
