Subject: [pycrypto] Unrecognized command line option '-mno-cygwin'
Message-ID: <000001cd5cd5$432a0870$c97e1950$@gmail.com>

I'm trying to build the pycrypto libarary. I browse to the folder where my
files are extracted an type 'make'. Things progress along just fine for
quite a few minutes when suddenly I get this error and the process halts:

 

Cc1.exe: error: unrecognized command line option '-mno-cygwin'

Error: command 'gcc' failed with exit status 1

 

I'm working in MinGW (not cygwin). Can anybody suggest how to fix this?
Thanks.

It is a known issue of distutils.

Edit C:\Python2.7.1\Lib\distutils\cygwincompiler.py and remove
'-mno-cygwin' everywhere.

Subject: [pycrypto] PyCrypto ElGamal code questions/comments
Message-ID: <4FFA7C53.2090306@gmail.com>

Hi,

I've been going over the code and I have a few questions. I realize that 
only few people are using this code, but hey, if it's good enough for a 
recent CVE :-)

  * The documentation of "generate" says that randfunc returns X random
    bytes. I think this should be bits.
  * The "generate" function is way too conservative. We construct p as
    2*q+1, where both p and q are prime. This makes p a classic "safe
    prime". It also makes two of the checks redundant: g cannot divide
    p-1, because only 2 and q divide it. g cannot be 2, and most likely
    will not be q during the lifetime of the universe. I believe that
    similarly, g**-1 cannot divide p-1, but my algebra skills are too
    rusty to prove it.
  * For the same reasons, there is no need for the loop when
    constructing K (the secret parameter), e.g. on line #342. You just
    need to ensure that it is an odd number, otherwise its GCD with p-1
    would be 2. So choose a random t, 2 < t < q-1, and let K=2*t+1. No
    need for a loop or for the GCD calculation.
  * An important check is missing: the message M needs to be less than
    p, both when signing and certainly when encrypting it.

Thanks,

     Yaron

With help from the mpir dev list, I built mpir.lib
Do you know where I should put it in pycrypto-2.6 ?
I ask because they are all python files so it is not clear where I should drop in a lib file.

Subject: [pycrypto] RSA output on long inputs can sometimes be gibberish
Message-ID: <CAHAkNZ3WBEBgMnDnPX6wKAxubE3EG9d94yBfizc=FRyKAq+22Q@mail.gmail.com>

I'm working on a project that includes a wrapper for cryptographic
encoding, which lets you express an "encryptor" as a JSON list. Of
course, this kinda hinges on the underlying cryptography code working,
and since I'm the sort of person who likes cryptographic privacy but
doesn't have an expert grasp on it, I make good use of my PyCrypto
dependency.

However, I *am* having issues regarding the RSA encryptor which delve
beyond my ken, and which may or may not indicate problems with the
underlying PyCrypto implementation. I wrote some test code and created
a bug report in my project:

https://github.com/campadrenalin/EJTP-lib-python/issues/9

The test involves the reversibility of the RSA process, using the
decrypt function on raw input as a bit of a hack to encrypt with the
private key (such that the public key can be used to decrypt it). This
matches the real-world functionality it will be used for, where data
at the innermost layer of encryption will be encrypted with the
sender's private key. This may seem silly, but it both acts as an
obfuscation and saves bandwidth (by accomplishing the intention of a
signature without the network overhead).

If sending raw data through the decrypt function is the problem, as I
suspect, then I can change the EJTP protocol to use proper signatures,
that's no biggy. But if this reveals problems in PyCrypto... I figured
you guys would want to know.

Anyways, my social anxiety and procrastination have delayed me from
this for long enough. Thank you for your time, and for PyCrypto being
excellent.

The code in ejtp/util/crypto/rsa.py looks like you're not doing proper padding
and using fixed sized blocks that don't depend on the key parameters. That won't
work.

You might want to have a look at PKCS#1 OAEP and pycrypto's
Crypto.Cipher.PKCS1_OAEP module [1].

Hi Yaron,

Some comments inline:

I am not 100% sure, but a common idiom in pycrypto is:

"
if randfunc is None:
     randfunc = Random.new().read
"

so randfunc(N) returns N bytes of full entropy.

I contributed to that part with a patch. My intention was actually to list
in the loop
as many criteria as possible that a generator safe for both Elgamal
encryption and Elgamal signatures (because .generate() does not know how
the key will be used) must fulfill.

It's true they are redundant in practice, but I think it's good to leave a
track behind with the general conditions that one must check, regardless of
how the domain parameters are computed.

 * For the same reasons, there is no need for the loop when

In the _sign() method I see only a loop to ensure that residues remains in
the range 0..p-1. The loop does not contribute to GDC computation.

True. Note that M must not the message when signing with PyCrypto's
Elgamal. It must be really be the cryptographic hash of the message.

So I have to install something called "mingw32" in order to install
pycrypto on windows, correct?

You need a C compiler. Visual Studio is also an option. There was a free version
around some years ago. I don't know if that's still the case.

Better, just install a pre-compiled version.  Here's a bunch: http://www.python.org/getit/

This is because you are on windows and setup.py is trying to run unix
commands.

To a cursory glance, it appears to be a bug in pycrypto's setup.py  It
should either provide a windows compatible way of performing autoconf
and friends (unlikely), or provide a windows alternative way of
configuring stuff and conditionally invoke the correct one for the system.

As I understand it, compiling and setting PyCrypto up from source on Windows
requires MinGW. It might also support Cygwin. But some sort of UNIX-y layer to
work with as common ground.

I could have sworn that I had managed in the past, but it appears that I
used pre-compiled for windows and did the building sensibly on Linux.

Apologies.

Subject: [pycrypto] chmod error in Windows 7, when trying to install
Message-ID: <20120907171002.D71CEE6739@smtp.hushmail.com>

I created a binary installer for the latest version of pycrypto if 
you would like it, let me know. If you don't trust meh bits(lul) 
then I have these notes from when I compiled pycrypto on windows:

Download the MinGW installer here: 
http://sourceforge.net/projects/mingw/files/Installer/mingw-get-
inst/mingw-get-inst-20120426/
Delete all references to -mno-cygwin in distutils\cygwinccompiler.py

>From within the pycrypto folder run: python setup.py build -c 
mingw32
Then run: python setup.py bdist_wininst
You will now have a compiled binary in: dist 

Run the binary on your host your ant pycrypto on and you should be 
all set.
