Lets say I use pycrypto with AES, like this.
obj = AES.new('mykey', AES.MODE_CFB)
mytext = "Big secret"
cipher = obj.encrypt(mytext)
Can I use the same key or I have to change it everytime?
Would this be sufficiently secure?

Hi,
Thank you for all the information, it seems like you think it easy to
do, as everyone accept to help me for free :-)
The solution used before was to send to encrypted string in clear in a
email. It used a perl impletation of the one-time pad.

ooh...terminology clarification:
OTP = one-time password
OTP = one-time pad
The former is a common tool used for safely logging in over an
insecure channel (such as using S/Key when logging into my
OpenBSD box over telnet).
i'll be honest, i don't know anyone who's ever used a one-time-pad
outside of some military applications before we had computers
everywhere. while the security is mathematically "perfect", it's so
encumbering to implement that i consider it overall riskier. having to
pass by courier gigs upo
Only one person (or very limited group) will receive the encrypted
message by email. It will hold customer information need by the sale
rep. So no user will have to deal with the encrypted data.
Server receive customer info -> encrypt critical info -> sent email to
sales rep.

They're all strong cryptographically,

Hi,
I'm building a web application for one of my clients with django. But
I need to do something that I have never did before and I am somehow
really short on time to learn it.
So I am looking for someone who has experience with encryption/
security in python. It is to be incorporated into my dj
