Making registery for my password login system.

hello,

Today i was trying to make a registery for my password login program only thing is im totally new at this stuff so im not sure how to make the registery.. i have the login all down good even added effects
but i wanted to take one step forward and make it so when you first run file/startup it will ask you what you want your username to be then your password also when you run the program again i need it to not re-register a new user.

i was thinking of making it part of startup and then have a if true/false statment so that it wont run that part of the program and go straight into logging in. so this makes is unhackable also the registery program on a disk so that i can add people to my computer if i want to also use that to edit my username and password.

os.pullEvent = os.pullEventRaw
term.setBackgroundColour(colours.white)
term.clear()
term.setTextColour(colours.grey)
local user = ""
local pass = ""
local i = 2
term.setCursorPos(3, 3)
print("			   running Applied-TechSecureure Startup 5.5V)
sleep(3)
term.clear()
term.setCursorPos(1, 1)
print("			Applied-TechSecure Startup")
term.setCursorPos(2, 2)
write("				  Username: ")
input = read("*")
if input == user then
else
term.setCursorPos(6, 8)
print("			   Please Wait...")
sleep(3)
term.setCursorPos(6, 8)
print("		   Username is incorrect")
sleep(3)
term.clear()
shell.run("startup")
end
term.setCursorPos(3, 3)
write("					 Password: ")
input = read("*")
term.clear()
term.setCursorPos(6, 8)
print("			   Please Wait...")
sleep(3)
if input == pass then
else
term.setCursorPos(6, 8)
print("		   Password is incorrect")
sleep(3)
term.clear()
term.setCursorPos(6, 8)
print("				Try Again Later")
sleep(4)
shell.run("startup")
end

   textutils.slowPrint("to this system.", 20)
   RegisterUser()
end


username()
if userNum ~= 1 then

end

NOTE: i did get this from another person but i was going to edit it for it to be compatible with my login program

knowing this i will have to redo my whole login program which im fine with but i need a bit of understanding on the registering part cause this one doesn't work.

Look into the fs API to save the username and password into a file (Wiki: Here. Tutorial: Here.), and then so that any old shmuck can't easily read the password i would run it through a Hash like Sha-256. (Here.)

And because i'm feeling generous you could easily do this.

if not fs.exists("Userinfo") then --#If the file that we're saving the username and pass into doesn't exist then we need to make it
  term.clear()
  term.setCursorPos(1,1)
  write("Enter desired username: ")
  local newuser = read()
  write("Enter desired password: ")
  local newpass = read("*")
  local file = fs.open("Userinfo","w")
  file.writeLine(newuser)
  file.writeLine(newpass)
  file.close()
end --#Since we're going to run the lock anyways, we don't need an else
local file = fs.open("Userinfo","r") --# Since we already know the file exists, and will have to exist, then we're good to open and read
local user = file.readLine()--#Reads the first line, which we saved the username on
local pass = file.readLine() --#Reads the second line which contains the password
file.close()
--#Good to ask for username and password.

Just put that at the top of your code, inside the os.pullEvent = os.pullEventRaw of course :P/>

Btw you should edit this line

print("				    running Applied-TechSecureure Startup 5.5V)

To this

print("				    running Applied-TechSecureure Startup 5.5V")

lol… thank you.. that was in my notepad… didnt fix it up :P/> but thank you for the tip! it will help out lots! question don't you need the program to save the file? i see that it opens it but what about saving?

It already does and is part of the fs API, i do believe that the file.close() closes it, however i don't exactly know of that fact.

Thank you so much! i was able to make it register and now all i need is the startup program read the userinfo file for its password thanks!

That's what i gave you on the post, that second bit stores it inside the user and pass variables
