Why?
I agree. Why wait? Put them in the stdlib now!
Can we please stop this?
I agree.
sorry I don't,
unless Python is only meant for the very well educated people in
encryption.
I haven't looked at the code but the functionality that's listed is
useful, e.g. in a Usenet client, and it's fun to play around with for a
beginner.
I neither did look at the code,
but as a beginner with just 3 years of experience in Python,
I've tried several scrambling libs, for a quick and dirty use.
All were much too difficult, so I made my own xor-something.
Coming from Delphi, a scrambling lib is working is less than 10 minutes,
without the need of any knowledge of encryption.
I prefer Python over Delphi, but some things are made very complex in
Python.
Are you sure?
def xor(s, key):
... return ''.join(chr(ord(c)^key) for c in s)
...
txt = "Hello world!"
xor(txt, 123)
'3\x1e\x17\x17\x14[\x0c\x14\t\x17\x1fZ'
xor(_, 123)
'Hello world!'
The Delphi code would be certainly longer than that, some variation of:
function encrypt_xor(const s: string; key: integer);
var
i: integer;
begin
SetLength(Result, length(s));
for i:=1 to length(s) do
begin
Result[i] := chr(ord(s[i]) xor key);
end;
end;
(untested)
