AES-256 requires a 256-bit key, period. However there are different ways of building that 256-bit key. One way is to generate 256 random bits and take them as the key. You need to store these 256 bits somewhere, or you won't be able to decrypt what you've encrypted.

- Crypto.PublicKey package¶. In a public key cryptography system, senders and receivers do not use the same key. Instead, the system defines a key pair, with one of the keys being confidential (private) and the other not (public).
- Nov 09, 2017 Questions: I’m trying to build two functions using PyCrypto that accept two parameters: the message and the key, and then encrypt/decrypt the message. I found several links on the web to help me out, but each one of them has flaws: This one at codekoala uses os.urandom, which is discouraged by PyCrypto. Moreover, the key.

I cannot seem to get py2exe to include the module crypto I have tried everything that i know. Please advise what to do. setup.py encode.py |

You didn't describe what happens when you try to do this. You might post screen shots or the like. |

@ryangurn py2exe does not work if some modules are in .egg form. install pycrypto with --always-unzip and easy_install .Example for me on windows and python 2.7 and 32 bit : easy_install.exe --always-unzip pycrypto-2.6.win32-py2.7.exe you don't need packages options anymore in your setup.py :more about this issue : http://www.py2exe.org/index.cgi/ExeWithEggs |

AES (Advanced Encryption Standard) is a symmetric block cipher standardizedby NIST . It has a fixed data block size of 16 bytes.Its keys can be 128, 192, or 256 bits long.
AES is very fast and secure, and it is the de facto standard for symmetricencryption.
As an example, encryption can be done as follows:

The recipient can obtain the original message using the same keyand the incoming triple
(nonce,ciphertext,tag)
