How can i encrypt and descrypt the created file above??
Well, as I was recently admonished (and have come to love), the
first recommendation is to use the "csv" module for writing CSV
files. It deals with oddities like quotation-escaping, and a
bunch of other details.
However, you want some sort of encryption/decryption method, but
you don't specify what type. You can do something simple like
def encrypt(s):
return s.encode('rot13')
def decrypt(s):
return s.decode('rot13')
f = open(filename, 'wb')
f.write(encrypt(content))
f.close()
f = open(filename, 'r')
content = decrypt(f.read())
f.close()
It's not very good encryption though ;-) For better encryption
see [1] & [2] for the pycrypto module. It's been a while since
I've done anything using this module, but the docs are available
for it and the basic premise is the same (encrypt the content
before writing, decrypt the content upon reading). It would help
to read up on crypto best-practices about storing key-files,
password-management, etc.
