this will help Java doesn't try to implement telepathic insight into web servers mostly for security reasons but mainly because no one could demonstrate such a technology is feasible.
What you can do is use a HTTP client framework like Apache's HttpComponent to talk to the server as if you were a web browser, fill in the form and submit it.

how do I change 'username-password login' to 'email-password login' on django-registration

To fix the issue you can do You can't easily store emails in django.contrib.auth.model.User's username field, so you'll need a different auth backend. Put the following somewhere and add its path to AUTHENTICATION_BACKENDS. See http://docs.djangoproject.com/en/dev/topics/auth/#writing-an-authentication-backend
code :
from django.contrib.auth.models import User

class EmailBackend(object):
    """ Authenticates against the email field of django.contrib.auth.models.User
    """

    def authenticate(self, email=None, password=None):
        # Try using the email if it is given
        if email:
            for user in User.objects.filter(email=email):
                if user.check_password(password):
                    return user

    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None
import uuid, binascii
username = binascii.b2a_base64(uuid.uuid4().bytes)

I wish this helpful for you I turns out that this function already exists: wp_authenticate();
It's just not documented in the codex at all! But you can look it up here.

Phpass - how to check login username and password against username and password hash in database

Hope that helps Here's how phpass works: When you save the user's password (when they create it) you hash it before saving, like so:
code :
$hash_iterations = 30;
$portable_hashes = FALSE;
$hasher = new PasswordHash($hash_iterations, $portable_hashes);
$hash_value = $hasher->HashPassword($actual_password);
// $stored_hash is the value you saved in the database for this user's password
// $user_input is the POST data from the user with the actual password
$valid_password = $hasher->CheckPassword($user_input, $stored_hash);

hop of those help? I wrote the following function to verify log in data for user, but so far its not working as it should and I am sure there is something wrong with it: , Try the following when adding parameter
code :
cmd.Parameters.AddWithValue("@AppUser", createuserAppUser.Text)
cmd.Parameters.AddWithValue("@AppUserPass", MD5StringHash(loginpasswordtx.Text))
cmd.Parameters.Add("@AppUser", SqlDbType.VarChar)       
cmd.Parameters("@AppUser").Value = createuserAppUser.Text
cmd.Parameters.Add("@AppUserPass", SqlDbType.VarChar)       
cmd.Parameters("@AppUserPass").Value = MD5StringHash(loginpasswordtx.Text)
SELECT COUNT(*) 
FROM OrderAppUsers
WHERE AppUser=@AppUser AND AppUserPass=@AppUserPass
Dim obj As int = Cint(cmd.ExecuteScalar())
If obj = 0 Then
    MsgBox("Faild to Log in, check your log in info")
    '' other codes
End If
Using cnn As New SqlConnection(My.Settings.SQLConnectionString)
    Using cmd = New SqlCommand("SELECT COUNT(*) FROM OrderAppUsers WHERE AppUser=@AppUser AND AppUserPass=@AppUserPass", cnn)
        cmd.Parameters.AddWithValue("@AppUser", createuserAppUser.Text)
        cmd.Parameters.AddWithValue("@AppUserPass", MD5StringHash(loginpasswordtx.Text))
        cmd.CommandType = CommandType.Text
        Try
            cnn.Open()
            Dim obj As int = Cint(cmd.ExecuteScalar())
            If obj = 0 Then
                MsgBox("Faild to Log in, check your log in info")
            Else
                 MsgBox("Logged in Successfully")
            End If
        Catch(ex As SqlException)
             MsgBox(ex.Message.ToString())
        End Try
    End Using
End Using

I think the issue was by ths following , I'm aware of the multiple posts and sources regarding how to loop and read from a text file. I'm sorry to be that guy but I'm a recent noob at Python and I'm writing this at 1:00 in the morning. , Let's say your text file (credentials.txt) reads:
code :
Janupedia
12345
print ("\nEnter details to access wallet...\n")
"""
Open File
"""
with open("Credentials.txt", "r") as f:
    array = []
    for line in f:
        array.append(line) #stores username and password
username = array[0]
password = array[1]
login = 0 #initial login status
while login == 0: #as long as login status = 0 loop repeats
    userInput = input("Username?")
    if username.strip(' \n') == userInput.strip(' \n'):
        userInput = input("Password?")  
        if password.strip(' \n') == userInput.strip(' \n'):
            login = 1 #login successful set login status to 1 thus breaking loop 
        else:
            print("Incorrect")
    else:
        print("Incorrect")
        print('\n--------------------------------------------------------\n')
#  Login successful loop finished
print("Welcome!")
print('\n--------------------------------------------------------\n')
print ("BTN = 0.10")
print ("= 315.37")
