RSA decryption of AES Session key fails with 'AttributeError: 'bytes' object has no attribute 'n'īut the answer to that question does not solve my issue. Why is an error thrown in Python cryptography RSA decryption of encrypted AES key Ask Question Asked 4 years, 11 months ago Modified 4 years, 11 months ago Viewed 4k times 3 I am trying to decrypt an AES key from a DER-encoded file that has been encrypted in RSA format. ModBits = (self._key.n)ĪttributeError: 'int' object has no attribute 'n' The session_key is actually encrypted correctly, but an AttributeError exception is always raised, with the following message: Traceback (most recent call last):įile '/usr/local/lib/python3.7/site-packages/Cryptodome/Cipher/PKCS1_OAEP.py', line 107, in encrypt The server gets the private key and uses it to encrypt a session key: data = conn.recv(271).decode()Įnc_session_key = cipher_rsa.encrypt(session_key) Public_key = key.publickey().exportKey('PEM') The following are 30 code examples of rsa.decrypt(). Key = RSA.generate(n_bin_size, None, e) # RsaKey object The client generates its RSA keys and sends the public one to a server: n_bin_size = 1024 Finally, decrypt the message using using RSA-OAEP with the RSA private key. I need to fix a client/server interaction based on P圜ryptodome. First, install the pycryptodome package, which is a powerful Python library.
