  1. An example of asymmetric encryption in python using a public/private keypair - utilizes RSA from PyCrypto library - RSAexample.py.
  2. Generate a new Customer Master Key using the Boto API or the AWS Console. Note that CMKs are region-specific, so you will need to generate keys per region in a multi-region configuration. Generate a Data Encryption Key via the generatedatakey API. This API will return the Plaintext key, so take care with this field and clear it from memory.
  3. From cryptography.fernet import Fernet key = Fernet. Generatekey ciphersuite = Fernet (key) ciphertext = ciphersuite. Encrypt (b 'A really secret message. Not for prying eyes.' Python 3 sample scripts from the examples in the HOWTO are also provided with the source and are accessible at gnupg.org.
  4. Windows (from sources, Python 2.x, Python Python 3.3 and 3.4) Windows (from sources, Python 3.5 and newer) Documentation; PGP verification; Compatibility with PyCrypto; API documentation; Examples. Encrypt data with AES; Generate an RSA key; Generate public key and private key; Encrypt data with RSA; Frequently.
  5. The following are code examples for showing how to use Crypto.PublicKey.RSA.generate.They are from open source Python projects. You can vote up the examples you like or vote down the ones you don't like.

Starting from PyCrypto 2.5 you can export an RSA private key and have it protected under a passphrase. A Triple DES key is internally derived from the passphrase and used to perform the actual encryption.

AWESOMESAUCE.

This only works because the 'mysecretpassword' is 16 bytes. If it were a different (not dividable by 16) amount of bytes you'd get
'ValueError: AES key must be either 16, 24, or 32 bytes long'
To avoid this the key may be hashed:
self.key = hashlib.sha256(key.encode('utf-8')).digest()

Very minor changes to make it python 3 compatible https://gist.github.com/mguezuraga/257a662a51dcde53a267e838e4d387cd

In Python 3 using the modifications of Craz1k0ek it still doesn't work with Unicode. For example the input Hello, 你好 raises ValueError: Input strings must be a multiple of 16 in length

Edit: found a working version: https://stackoverflow.com/a/44212550

i think this is aes 128, we have a standard blocksize of 16 bytes (128bit)

commented Apr 26, 2018

i can't seem to find how to do aes256
