问题 I am having around 19G of data which I am doing tar and then encrypt. I use below code to do the job. from subprocess import call from Crypto.Cipher import AES from Crypto.Random import get_random_bytes import sys cmd = ["tar","--acls","--selinux","-czPf","./out.tar.gz","./src"] proc = call(cmd) data = open("./out.tar.gz", "rb").read() key = get_random_bytes(32) cipher = AES.new(key, AES.MODE_GCM) ciphertext, tag = cipher.encrypt_and_digest(data) out = open("./out.bin", "wb") [out.write(x)

问题 I have installed pycryptodomex module on python 3.6.5 but when i try to execute the below call, i get the error mentioned in the headline from Crypto.Cipher import AES I want to encrypt a file using AES. How to proceed now ? 回答1: >> pip install pycryptodome from Crypto.Cipher import AES #Works or >> pip install pycryptodomex from Cryptodome.Cipher import AES For python3 the package name is now pycryptodome or pycryptodomex If you need compatibility with your project with Python2 use

Today I saw PySNMP installing pycryptodomex. The x in that name looked suspicious and surprising. I tried to track it down, but it looks like both pycryptodome and pycryptodomex are owned by the same account and point back to the same Github repository . Especially because a cryptography library is a core security feature, I'm suspicious of the duplication. What's the purpose of this duplication? Could I have discovered this information from open sources? Emmanuel Ferran It's the same code, just different names. pycryptodome has some association to pyCrypto and can be considered a drop in
