问题 First I tried pip install pycryptodome and the it says following error from Crypto.Cipher import AES ModuleNotFoundError: No module named 'Crypto' 回答1: Check the section why-do-i-get-the-error-no-module-named-crypto-on-windows on the pycryptodome documentation page. I hit the same issue when I first installed the incorrect module crypto instead of pycryptodome. In this case, follow this to correct the imports: pip uninstall crypto pip uninstall pycryptodome pip install pycryptodome 来源： https:

问题 I was trying to install pycryptodome , python-jose-cryptodome using pip within anaocnda3 environment. I got this error: ERROR: Failed building wheel for pycryptodome I have tried many versions many solutions(latest versions, specified version, with python 3.8 or 3.7, using requirements text without cache and even alone installation) but nothing worked for me :(. Any solution? 回答1: While using pip in an anaconda environment is allowed and fine, issues may arise when using pip and conda

python 实现 AES CBC模式加解密

AES加密方式有五种：ECB, CBC, CTR, CFB, OFB 从安全性角度推荐CBC加密方法，本文介绍了CBC,ECB两种加密方法的python实现 python 在 Windows 下使用AES时要安装的是pycryptodome 模块 pip install pycryptodome python 在 Linux 下使用AES时要安装的是pycrypto模块 pip install pycrypto CBC加密需要一个十六位的key(密钥)和一个十六位iv(偏移量) 1. 加密 加密时，明文首先与IV异或，然后将结果进行块加密，得到的输出就是密文，同时本次的输出密文作为下一个块加密的IV。 2. 解密 解密时，先将密文的第一个块进行块解密，然后将结果与IV异或，就能得到明文，同时，本次解密的输入密文作为下一个块解密的IV。 3. 代码： 　　 # -*- coding=utf-8-*- from Crypto.Cipher import AES import os from Crypto import Random import base64 """ aes加密算法 padding : PKCS7 """ class AESUtil: __BLOCK_SIZE_16 = BLOCK_SIZE_16 = AES.block_size @staticmethod def

PyCryptodome Error: MAC Check Failed

问题 I am working on an encryption program with Pycryptodome in Python 3. I am trying to encrypt a (byte) string and then decrypt it and verify the MAC tag. When I get to verify it, an error is thrown. This is the code: from Crypto.Cipher import AES from Crypto.Random import get_random_bytes aes_key = get_random_bytes(24) aes_cipher = AES.new(aes_key, AES.MODE_GCM) encrypted, MACtag = aes_cipher.encrypt_and_digest(b"A random thirty two byte string.") # Imagine this is happening somewhere else new

Get the counter value after decrypt finished

问题 I am trying to decrypt AES-CTR in SSH using the keys generated by the openssh/openssh-portable library. I extracted the keys successfully from memory. Now, after some printfs and research I found out that it seems like the initial counter is incremented for every encrypted packet, which means that a successor packet(not byte) has a different Counter value as the pre-packet. For my decryption I want to decrypt packet by packet, so now my question is: Can I somehow get the "end" counter of the

Skipping elif statement?

问题 Am trying to create a simple encryption/decryption using pycryptodome but keeping getting the following error: ValueError: Error 3 while encrypting in CBC mode after some digging I saw that you get this error if there is not enough data to encrypt, as in there is no padding in effect. The thing is that I've added a padding function. After debugging it seems as if my code literally skips the padding part completely and causes this error. What am I doing wrong? import os, random from Crypto

What is pycryptodomex and how does it differ from pycryptodome?

问题 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? 回答1: It's the same code, just
