17:28 TalkLounge joined #minetest
17:31 TalkLounge Hello, I reprogrammed my Minetest Main Menu a little bit, so if I you join the first time on a server, your password will save in a .txt file and after that you only press connect and the password will be filed in automaticly
17:32 sfan5 you should consider sending a pull request on github
17:32 TalkLounge So if you open minetest you first enter the decrpytionkey
17:33 TalkLounge So the decryptionkey should be saved until you close Minetest
17:33 TalkLounge How can I do that?
17:33 sfan5 ok that sounds terrible because i assume you implemented some kind of "encryption" yourself
17:34 rubenwardy make sure you use a well known one, like AES-256
17:34 sfan5 that's not enough
17:35 TalkLounge Yes, because the passwords for the server shouldn´t be in the file, because everyone how see the file, you know your passwords
17:36 red-001 could you add a checkbox to save the password and only save if after the user logs in successfully?
17:36 TalkLounge The encryption is not the problem, the problem is, that I didnt find a way to save the encryptionkey you tipe when you start minetest and delete the key, when you close minetest
17:36 sfan5 you can just save that in a text file tho
17:36 sfan5 too*
17:37 red-001 if you are saving the key then whats the point of using it?
17:37 TalkLounge Yes, but how I check if you close Minetest to delete the encryptionkey?
17:37 rubenwardy I'd store it in C++ somewhere, and make an API
17:38 rubenwardy for the main menu
17:38 sfan5 red-001: obfuscation
17:38 TalkLounge Yes.... But then I must compile a new minetest
17:38 sfan5 pretty sure chrome does this too, your passwords are not 100% safe but you can't just grab then from the sqlite file without effort
17:39 TalkLounge And I want to public that "mod" in the forum, if it work
17:39 TalkLounge And I dont want to add a new minetest
17:39 red-001 I makes even less sense for chrome and firefox
17:39 red-001 it*
17:39 sfan5 why
17:39 red-001 since you can just view the passwords in browser
17:40 rubenwardy in firefox your passwords are encrypted using your master password, if you have one set
17:40 sfan5 that's not the point
17:40 rubenwardy and you need to enter it on each load
17:40 red-001 ah good point I forgot you could set that
17:40 TalkLounge Is there a way to check via lua, if you have closed minetest or something like that, or something what will be reset ervy time, when you close minetest
17:40 rubenwardy no
17:40 rubenwardy if you exit from a game, it won't run the main menu again
17:41 rubenwardy exit from a game -> to the OS
17:41 rubenwardy if you don't want to make this an engine contribution the only thing you can do is make it per main menu load and put it in a local
17:42 TalkLounge It would be nice, if I can add a variable and add the password in there
17:42 TalkLounge Because a variable you cant check without restart minetest
17:44 rubenwardy we're free from the matrix spies!
17:45 sfan5 something something next-generation protocol
17:45 TalkLounge I have tried to save the encryptionkey in the minetest/builtin/init.lua but that lua will be reset every time, if you connect to a server
17:45 sfan5 just save it into a text file
17:45 Krock something something better, more reliable protocol ;)
17:46 TalkLounge But how I delete the textfile, if I close minetest?
17:46 rubenwardy you can't
17:46 TalkLounge Is there some syntax for that?
17:46 sfan5 why do you want to store something in a text file only while mt is open?
17:46 Krock ^ if you got to do that, it's unsafe anyway
17:47 Krock the encryption, I mean
17:47 TalkLounge Yes
17:47 TalkLounge too
17:48 TalkLounge The whole encryption is useless, if you save the encryptionpassword in a textfile
17:48 soloojos joined #minetest
17:48 Guest49560 joined #minetest
17:48 TalkLounge Then I can save the passwords direct in the file
17:48 TalkLounge You know waht I mean?
17:49 TalkLounge what
17:50 TalkLounge I know that encryption is never 100% save, but 25% encryption is even better then no encryption
17:50 Krock > WPA2
17:50 TalkLounge Thats the WLAN encryption
17:50 red-001 what encryption system are you using
17:51 red-001 TalkLounge, that was broken recently
17:51 sfan5 wpa2 wasn't broken
17:51 Krock When you develop a secure Wireless encryption and somewhen you shoot yourself into the knees because the 3rd packet can be sent again to crack it
17:51 rubenwardy just store it in a local variable, and require it to be entered each time the main menu is reloaded (preferably with a button rather than a forced dialog)
17:51 Taose joined #minetest
17:51 TalkLounge Nice Idea
17:51 Krock well, it's a protocol issue as much as I heard
17:52 TalkLounge A onclick event on the mainmenu button on esc
17:52 TalkLounge That should work I think
17:52 rubenwardy ?
17:52 red-001 sfan5, a reply attack was found that can be used to decrypt traffic
17:53 sfan5 this is an implementation problem
17:53 red-001 it's not through
17:53 red-001 it's a design problem
17:53 sfan5 it does not make the protocol inherently unsaf
17:53 sfan5 e
17:54 TalkLounge Yes if you click the mainmanu button at esc, then the variable where your encryptionkey is saved saved again in the variable
17:55 TalkLounge You know what I mean?
17:55 TalkLounge Its a good idea, if this work is a other question
17:56 TalkLounge Someone other have any idea?
17:57 rubenwardy not sure what you mean
17:59 TalkLounge Another idea is, that I add a file, which destroy itselfs if the dont get a signal from a csm or something like that
17:59 red-001 why not hard code the key in the code? It would work about as well
17:59 TalkLounge This is half save
17:59 TalkLounge But it should work
17:59 rubenwardy lol
18:00 TalkLounge Then theres no enrcyption...
18:00 red-001 I mean there really isn't if you are storing the key on the harddrive with no protection
18:01 Krock who says the HDD contents aren't encrypted?
18:01 red-001 Krock, moot point
18:04 sofar just ask the player for their password every client start
18:04 sofar bonus points if you make player profiles
18:05 bas080 joined #minetest
18:06 TalkLounge I will test the two options and if it work, I publish it on the forum
18:06 TalkLounge Thanks for your ideas
18:06 TalkLounge Bye

23:33 Flairieve Does the Minetest lua API have LuaJIT and FFI in it?
23:34 rubenwardy that doesn't really make sense as a question
23:34 rubenwardy Minetest can be compiled with LuaJIT
