I'v been working on a chatting program for a couple of hours now and all seems to be going good, I threw in some random features and so on... but what I really need is someone to review my work. The only person that I had review my work ATM was my cousin who is more of a C/C++ programmer...
I used the code from the ECHO Client/Server example on the python.org website to start me off but the rest of the code is mine.
THIS IS MY SOURCE FOR THE CLIENT:
:
#Message Client Program written originally by: Beegie_B
#This program and the server prorgam are both Original copies of Beegie_B's
#Simple python messaging Client/Server
#Feel free to edit but leave reference to original writer
#Thank you Python.org for your great socket examples and Echo Server Example
import socket
import en_de_crypt # Imports Beegie_B's Encryption Module
from en_de_crypt import *
HOST = '**.**.**.**' # The remote host
PORT = 50007 # The same port as used by the server
x = "" # Random Variable that Stores The Message
null = " "
user = raw_input("Username:")
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
s.send(user)
user = s.recv(1024)
while x != "<exit>":
print
data = s.recv(1024)
print "%s>>>%s"% (user, data)
x = raw_input(">>>")
if x[:8].lower() == "encrypt:":
x = x[8:]
x = encrypt(x)
s.send(x)
elif x[:8].lower() == "decrypt:":
x = x[8:]
x = decrypt(x)
print "Decrypted Message:%s"%(x)
s.send(null)
else:
s.send(x)
s.close()
and HERE IS THE SOURCE FOR THE SERVER:
:
#Message Server Program written originally by: Beegie_B
#This program and the client prorgam are both Original copies of Beegie_B's
#Simple python messaging Client/Server
#Feel free to edit but leave reference to original writer
#Thank you Python.org for your great socket examples and Echo Server Example
import socket
import en_de_crypt # Imports Beegie_B's Encryption Module
from en_de_crypt import *
HOST = '' # Symbolic name meaning the local host
PORT = 50007 # Arbitrary non-privileged port
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(1)
x = "" # Random Variable that Stores The Message
null = " "
user = raw_input("Username:")
while x != "<exit>":
conn, addr = s.accept()
conn.send(user)
user = conn.recv(1024)
print 'Connected by', addr, "----", user
while x != "<exit>":
print
x = raw_input(">>> ")
if x[:8].lower() == "encrypt:":
x = x[8:]
x = encrypt(x)
conn.send(x)
elif x[:8].lower() == "decrypt:":
x = x[8:]
x = decrypt(x)
print "Decrypted Message:%s"%(x)
conn.send(null)
else:
conn.send(x)
data = conn.recv(1024)
if not data: break
print "%s>>>%s"% (user, data)
conn.close()
AND FINALLY THE SOURCE FOR THE ENCRYPT MODUAL:
:
#A Simple Python Text Encrypter and Decrypter by Beegie_B
#Use With any program that needs an encryption job!
def encrypt(word):
transTable = {
'a': 'f',
'b': 'd',
'c': 'i',
'd': 'a',
'e': 's',
'f': 'j',
'g': 'c',
'h': 'z',
'i': 'b',
'j': 'h',
'k': 'w',
'l': 'k',
'm': 'e',
'n': 'y',
'o': 'v',
'p': 'n',
'q': 'g',
'r': 'o',
's': 'x',
't': 'l',
'u': 'r',
'v': 'm',
'w': 't',
'y': 'p',
'x': 'q',
'z': 'u'
}
newWord = []
for letter in word.lower():
try:
newWord.append(transTable[letter])
except KeyError:
newWord.append(letter)
return ''.join(newWord)
def decrypt(word):
transTable = {
'a': 'd',
'b': 'i',
'c': 'g',
'd': 'b',
'e': 'm',
'f': 'a',
'g': 'q',
'h': 'j',
'i': 'c',
'j': 'f',
'k': 'l',
'l': 't',
'm': 'v',
'n': 'p',
'o': 'r',
'p': 'y',
'q': 'x',
'r': 'u',
's': 'e',
't': 'w',
'u': 'z',
'v': 'o',
'w': 'k',
'x': 's',
'y': 'n',
'z': 'h'
}
newWord = []
for letter in word.lower():
try:
newWord.append(transTable[letter])
except KeyError:
newWord.append(letter)
return ''.join(newWord)
Does anyone have any Idea's of what I can do to improve this program?
I'v been trying to allow multipul clients to connect to the server and getting rid of the problem where you have to recive a message before sending one, but all my attempts failed... if anyone has any tips for me they would be greatly appreciated :D
Beeg
NOTE: Some other programs I have finished are: an IP scanner (somewhat buggy and works best in win), a Port Scanner (minor bugs and somewhat slow), and an Online Link Checker (also very buggy) |
