+>>> 1. A Basic Login System with Python
+
+Concept
+
+The program will accept the user’s email and password, hash the password, store it into a text file with the email, and complete the registration process.
+
+
+Prerequisites
+
+You should have installed python version 3.0 or above to use the built-in package hashlib.
+
+
+import hashlib
+def signup():
+    email = input(“Enter email address: “)
+    pwd = input(“Enter password: “)
+    conf_pwd = input(“Confirm password: “)    if conf_pwd == pwd:
+        enc = conf_pwd.encode()
+        hash1 = hashlib.md5(enc).hexdigest()        with open(“credentials.txt”, “w”) as f:
+             f.write(email + “\n”)
+             f.write(hash1)
+        f.close()
+        print(“You have registered successfully!”)    else:
+        print(“Password is not same as above! \n”)def login():
+    email = input(“Enter email: “)
+    pwd = input(“Enter password: “)    auth = pwd.encode()
+    auth_hash = hashlib.md5(auth).hexdigest()
+    with open(“credentials.txt”, “r”) as f:
+        stored_email, stored_pwd = f.read().split(“\n”)
+    f.close()    if email == stored_email and auth_hash == stored_pwd:
+         print(“Logged in Successfully!”)
+     else:
+         print(“Login failed! \n”)while 1:
+    print("********** Login System **********")
+    print("1.Signup")
+    print("2.Login")
+    print("3.Exit")
+    ch = int(input("Enter your choice: "))
+    if ch == 1:
+        signup()
+    elif ch == 2:
+        login()
+    elif ch == 3:
+        break
+    else:
+        print("Wrong Choice!")
