# Simplified AES
Simplified AES (S-AES) is an educational tool designed to help students learn the structure of AES using smaller blocks and keys.
- Non-feistal block cipher
- Plaintext: 16 bit
- Key: 16 bit
- Ciphertext: 16 bit
SAES Structure
Key Expansion
## Usage
Use the `SimplifiedAES` class in your program as follows.
For encryption:
```python
from saes import SimplifiedAES
plaintext = 0b1101011100101000
key = 0b0100101011110101
ciphertext = SimplifiedAES(key).encrypt(plaintext) # 0b0010010011101100
```
For decryption:
```python
from saes import SimplifiedAES
ciphertext = 0b0010010011101100
key = 0b0100101011110101
plaintext = SimplifiedAES(key).decrypt(ciphertext) # 0b1101011100101000
```
