what is the best/easiest to use encryption library in python

Question

I want to encrypt few files using python what is the best way i can use gpg but are there any standarad/famous python libraries?

Answer 1

PyCrypto seems to be the best one around.

Answer 2

Try KeyCzar

Very easy to implement.

Answer 3

See Google's Keyczar project, which provides a nice set of interfaces to PyCrypto's functionality.

Answer 4

I use GPGme The main strength of GPGme is that it read and writes files at the OpenPGP standard (RFC 4880) which can be important if you want to interoperate with other PGP programs.

It has a Python interface. Warning: it is a low-level interface, not very Pythonic.

If you read French, see examples.

Here is one, to check a signature:

signed = core.Data(sys.stdin.read())
plain = core.Data()
context = core.Context()

context.op_verify(signed, None, plain)
result = context.op_verify_result()

sign = result.signatures
while sign:
    if sign.status != 0:
        print "BAD signature from:"
    else:
        print "Good signature from:"
    print "  uid:        ", context.get_key(sign.fpr, 0).uids.uid
    print "  timestamp:  ", sign.timestamp
    print "  fingerprint:", sign.fpr
    sign = sign.next

Answer 5

I like pyDes (http://twhiteman.netfirms.com/des.html). It's not the quickest, but it's pure Python and works very well for small amounts of encrypted data.

Answer 6

I use pyOpenSSL, its a python binding for OpenSSL which has been around for a long time and is very well tested. I did some benchmarks for my application, which is very crypto intensive and it won hands down against pyCrypto. YMMV.
