Hi,
I want to say first of all that I'm totally a newbie in cryptography world.
Is there someone can show me a simple example on how to use PyCrypto lib and
RSA to encrypt large text file? I'm trying to do it in this way.
First of all I split the text file in sub parts each one of key.size() // 8
size. Then I encrypt using RSA PublicKey algorithm and store each line in a
target file. This is the pseudo-code:
size = len(plaintext)
bits...

The location of the prebuilt windows installer for PyCypto 2.0 (for
python 2.4) has changed. Apologies for any confusion, this is because of
a website reorganisation at Voidspace.
The new location is :
http://www.voidspace.org.uk/python/modules.shtml#pycrypto
There is also a prebuilt windows installer for psyco 1.4 (for python
2.4). This is because there isn't yet a prebuilt binary available from
sourceforge.

Does anyone know if pycrypto is active at all. I have been browsing
groups etc. for some info and have found entries from 2003 (latest)
regarding some bits I was looking for in particular reference to

I'm trying to write an IM client which sends encrypted messages to the
server. I tried to use pycrypto library, but when I came to 3DES
cypher I was confused about the keysize to use. In the standard it
said that it should be either 112 bits or 168 bits, whereas it's 16
bytes or 24 bytes in pycrypto. If I use 16 bytes key to encrypt and
send this key to the server which is expecting a 112 bits key, there'll
be a problem. How I should...

Operating system: Win XP
Vsn of Python: 2.4
Situation is this: Required to calcluate a message digest. The process
for calcluating the digest must use an SHA-256 algorithm.
Questions:
1) Is it correct that the sha module comes with python 2.4?
2) Is it correct that the sha module that ships with python 2.4 does
NOT have the SHA-256 capability as part of the module?

Attempting to determine whether the PyCrypto package has the capability
to perform AES256 encryption. I received the following C# snippet:
CryptoProvider provider = new CryptoProvider();
Encrypted_Type password = new Encrypted_Type();
password.EncryptedData = new EncryptedDataType();
password.EncryptedData.EncryptionMethod = new EncryptionMethodType();
password.EncryptedData.EncryptionMethod.Algorithm = "AES256-cbc";

I snipped this bit of code out of Andrew Kuchling 'pyCrypto' test
fixture. Having a need to XOR Binascii Hex strings in my current
project, I found it very helpful to cut down on a bit of code
clutter.
So if you have a need for a Crypto module, this one seems to work off
the self without much effort and it comes /w a nice XOR function too
boot. :-)

I am really stuck presently, trying to install these on my Windows XP.
I have downloaded easy_install and it is now in Python25\Scripts but
none of the commands I have read in either program folder have worked
to install them.
I was hoping someone could give me a step by step guide to installing
these so I can use paramiko to perform SSH. Or at least point me in
the right direction...
Thanks

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
