Hi,
I'd like to read several strings by using 'input'.
These strings are separated by white space but I'd like to allow for
some quoting, e.g.

Is there a simple way

c = crypt.encrypt(txt)
txt_plain=crypt.decrypt(c)
print txt_plain
Unfortunately, txt_plain differs from txt - why?
(Using MODE_ECB does work however)
What am I missing?

Hi,
I've just tried to write a simple example using PyCrypto's
AES (CBC mode)
#!/usr/bin/python
from Crypto.Cipher import AES
PWD='abcdefghijklmnop'
Initial16bytes='0123456789ABCDEF'
crypt = AES.new(PWD, AES.MODE_CBC,Initial16bytes)
# crypt = AES.new(PWD, AES.MODE_ECB
the lines of it like
for line in EQ_OUT :

I could use StringIO.StringIO applied to EQ_output
but this reads all of the command's output into a big
string first.
On Unix/Linux a pipe is a file-like object after all,
so how to get hold of it.
Many thanks for a hint,

EQ.stdout is the filelike object you're looking for.
communicate() grabs entire output at once so don't use it.
Thanks a lot, I haven't found that in the official documentation.
Helmut.
That would be a documentation bug

Is this writable _encoding attribute, with a leading underscore (_),
documented anywhere? Does it actually work? Would it happen to be
supported
of a script.
Why isn't that possible?

I wished I could override the locale settings within a Python script.
