File.open_encrypted_with_pass() returns ERR_FILE_UNRECOGNIZED

[vicguedez]

Godot version:
3.1.1.stable-official

OS/device including version:
Windows 7

Issue description:
If you try to read or write a file using File.open_encrypted_with_pass() it returns ERR_FILE_UNRECOGNIZED and doesn't say much more.

Windows cmd displays:

ERROR: open_and_parse: Condition ` magic != 0x43454447 ` is true. returned: ERR_FILE_UNRECOGNIZED
    At: core/io/file_access_encrypted.cpp:65

Steps to reproduce:

var file : File = File.new()
var open_result = file.open_encrypted_with_pass("user://user.json", File.WRITE_READ, OS.get_unique_id())

print("Open result ", open_result)

I try your reproduce in my laptop is window10, and it have another problem, So I think may could change the way to read and write the file, for example:

func save(content):
    var file = File.new()
    file.open("user://save_game.dat", File.WRITE)
    file.store_string(content)
    file.close()

Here is the link I found,I hope this will help you https://docs.godotengine.org/en/3.1/classes/class_file.html

Still valid in 3.2.3
Looks like open_encrypted_with_pass() doesn't support WRITE_READ mode, not sure if it's intended.

Still happens in 4.0-beta13 with the new FileAccess API.

[MatiasVME]

Still happens in versions 4.2.1 and 4.2.2 and 4.3-beta3

The file is supposed to be created if I do the following:

extends Node2D


func _ready():
	var _file_path := "user://my_file.save"
	
	var file = FileAccess.open_encrypted_with_pass(
		_file_path,
		FileAccess.WRITE_READ,
		"123456"
	)
	var _error = FileAccess.get_open_error()
	var content = file.get_var()
	file.close()

I am using:
