How can I decrypt something with PyCrypto that was encrypted using OpenSSL?

I have several strings that were encrypted using OpenSSL. For instance: $ echo "original string" | openssl aes-256-cbc -p -a -pass pass:secret salt=B898FE40EC8155FD key=4899E518743EB0584B0811AE559ED8AD9F0B5FA31B0B998FEB8453B8E3A7B36C iv =EFA6105F30F6C462B3D135725A6E1618 U2FsdGVkX1+4mP5A7IFV/VcgRs4ci/yupMErHjf5bkT5XrcowXK7z3VyyV1l2jvy I would like to decrypt these things using Python. I'm attempting to use PyCrypto. Here's an exmaple script using the above data: from base64 import b64decode, b64encode from hashlib import md5 from Crypto.Cipher import AES secret = 'secret' encoded = 'U2FsdGVkX1

问题 Why Pycrypto AES decryption gives different output when decrypted with AES object used for encryption and right output when decrypted with AES object used solely for decryption? from Crypto.Cipher import AES obj = AES.new('0123456789012345', AES.MODE_CBC, '0123456789012345') message = '0123456789012345' ciphertext = obj.encrypt(message) plaintext = obj.decrypt(ciphertext) # plaintext here is byte array obj2 = AES.new('0123456789012345', AES.MODE_CBC, '0123456789012345') plaintext = obj2

问题 I am just starting to explore Python. I am trying to run an AES algorithm code and I am facing the: ImportError: No module named Crypto. How do you solve this? 回答1: You have to install crypto package. https://pypi.python.org/pypi/pycrypto 回答2: Solution : By installing pycrypto module from your virtualenv pip install pycrypto 回答3: Solved when i installed pycrypto rather then crypto pip2 install pycrypto 来源: https://stackoverflow.com/questions/30738083/importerror-no-module-named-crypto

Encrypt with Node.js AES CTR and decrypt with PyCrypto

喜夏-厌秋 提交于 2019-12-06 15:39:13
Okay, so basically I am having issues decrypting with Python. I've managed to encrypt/decrypt data with Node.js - using "aes-128-ctr", the same goes for PyCrypto, but when I try to encrypt with Node.js and decrypt with Python I get invalid deciphered text. Node.js code: var key = "1234567890123456"; var cipher = crypto.createCipher("aes-128-ctr",key) var ctext = cipher.update('asasasa','utf8','hex') + cipher.final('hex') console.log(ctext) // outputs: "f2cf6ecd8f" Python code: counter = Counter.new(128) cipher = AES.new("1234567890123456", AES.MODE_CTR, counter=counter) cipher.decrypt(

How to generate the PEM serialization for the public RSA/DSA key

拈花ヽ惹草 提交于 2019-12-06 02:02:21
问题 Using PyCrypto I was able to generate the public and private PEM serialization for a RSA key, but in PyCrypto the DSA class has no exportKey() method. Trying PyOpenSSL I was able to generate the private PEM serialization for RSA and DSA keys, bu there is no crypto.dump_publickey method in PyOpenSSL. I am looking for suggestion of how to generate the PEM serialization for RSA and DSA keys. Many thanks! PS: meanwhile I have changed the PyOpenSSL code to also export an dump_privatekey method for

How do you use pycrypto with GAP? It says here that it does not support the latest version. Does that mean that I have to use the version pointed by them ? I tried this but, when I execute setup.py I get the error src/MD2.c:15:20: fatal error: Python.h: No such file or directory compilation terminated. error: command 'gcc' failed with exit status 1 App Engine 1.7.2, released just a few hours ago, now supports PyCrypto 2.6, the most recent version. The linked doc is likely outdated and will be updated soon. You can use it by instructing app engine to include it . To make GAE use pycrypto, you

Decrypt using an RSA public key with PyCrypto

问题 As far as I understand, I should be able to use RSA to ensure authenticity or privacy, as I wish. In my case, I want to ensure authenticity so I encrypt the data with the private key and allow anyone to decrypt it with the public key. The data is not really secret but I need to guarantee that it was created by the owner of the public (and private) key. When I try to decrypt using PyCrypto I get No private key error from PyCrypto. The code is this: def _decrypt_rsa(decrypt_key_file, cipher
