well, i started messing around with dictionaries, yet, most of the pages i found about them always talk about getting only one word out of it and turning it vice versa, i've been playing with that code for a few hours: -

Decryption=dict(zip(Encryption.values(), Encryption.keys()))

trying to get an output from the reversed dictionary is just not working, keeps giving me KeyErrors, even i enter only 1 word that is IN the dictionary...
maybe it's because didn't use conventional letters, but still, how do i decrypt?
plz help
#Note: the Encryption works perfectly, the Decryption Doesn't.
I'm using python 2.5 (python 3 is weird O|o)

You are iterating on the string in decrypt(). That means you are considering only one letter at a time. Try this instead: - def decrypt(y):
-
for key in Decryption:
-
if key in y:
-
while True:
-
try:
-
i = y.index(key)
-
y = y[:i]+Decryption[key]+y[i+len(key):]
-
except:
-
break
-
return y
Example: - >>> s = encrypt('temple of doom')
-
>>> s
-
'joq%aon[d:w]nt|;d^faonh4x0r2{par:queh4x0r2maw{par:{par:[d:w]'
-
>>> decrypt(s)
-
'temple of doom'
-
>>>
Oh, so this is how it's done...
the return is bugging it =/ changed it to print

There probably is a better way to do it. :)
I generally prefer to return an object from a function then format the output as required. Using an IDE makes testing code much easier. In your case: - s = encrypt('temple of doom')
-
print s
-
print decrypt(s)

On my Fedora Core 2 Linux dev box, I have installed mcrypt and
compiled PHP with the --with-mcrypt option. I am concerned that when
I move to another hosting enviornment mcrypt will not be supported.
In people's experiences, have hosting companies supporting PHP/MySQL
generally provided support for mcrypt?
Does anyone recommend another module for encryption/decryption that
accompanies the PHP package?
Thanks, - Dave
