This library has been written to make encryption / decryption of any python object as simple as possible, while keeping the encryption solution secure.
It is based on pycryptodomex AES and RSA encrpytion implementations.

It's main features are:
 - Encrypt any pickable Python object / variable / blob
 - Add an UTC timestamp to the encrypted message
 - Verify that decrypted messages timestamps aren't in the future or too old (for bad RTC clock diags)
 - Allow symmetric encryption (AES-EAX mode)
     - 128, 192 or 256 bits encryption
 - Allow asymmetric encryption (RSA encryption with SHA384 hash algorithm and above AES encryption)
     - 1024, 2048 or 4096 bits RSA encryption with AES-256 session encryption
 - Provide the encypted data as base64 string for maximum portability between platforms and encodings
 - Unload AES key from memory as soon as possible to help prevent memory attacks

# Setup

cryptidy requires Python 2.7+

`pip install cryptidy`


# Symmetric encryption usage

```
from cryptidy import symmetric_encryption

key = symmetric_encryption.generate_key(32)  # 32 bytes == 256 bits

some_python_objects = ['foo', 'bar'], 'some long string', 12
encrypted = symmetric_encryption.encrypt_message(some_python_objects, key)
timestamp, original_object = symmetric_encryption.decrypt_message(encrypted, key)
```

# Asymmetric encryption usage

```
from cryptidy import asymmetric_encryption

priv_key, pub_key = asymmetric_encryption.generate_keys(2048)  # 2048 bits RSA key

some_python_objects = ['foo', 'bar'], 'some long string', 12
encrypted = asymmetric_encryption.encrypt_message(some_python_objects, pub_key)
timestamp, original_object = asymmetric_encryption.decrypt_message(encrypted, priv_key)
```
