# CHANGELOG

## [1.2.0] - 20924/12/27
### Added
- **Type Encoding and Decoding Tools**:
  - Added `TypeEncodeDecodeTools` class with various utility methods:
    - `int_list_to_str` and `str_to_int_list`: Convert between integer lists and strings.
    - `float_to_bytes` and `bytes_to_float`: Convert between floats and bytes.
    - `hex_string_format_to_bytes` and `bytes_to_hex_string_format`: Handle hex string and byte conversions.
    - `int_to_int_list` and `int_list_to_int`: Convert integers to byte lists with MSB/LSB ordering and back.
    - Other similar encoding/decoding tools.
- Comprehensive unit tests for the new `TypeEncodeDecodeTools` in `test_type_encode_decode_tools.py`.

### Fixed
- None

---

## Features

- **Error Detection Tools**: Implementations of BCC, CRC, Parity Check, and LRC for data integrity checks.
- **Irreversible Encryption**: Secure hashing algorithms like SHA-256, SHA-512, and bcrypt.
- **Reversible Encryption**: Symmetric and asymmetric encryption algorithms including AES, Twofish, RSA, and ECC.
- **Type Encoding and Decoding**: Tools for type conversion and encoding/decoding operations, such as integer-to-string, hex-to-bytes, and more.

---

## Installation

You can install Atom Encryption from PyPI:

```bash
pip install atom-encryption
```

Or clone the repository and install it locally:

```bash
git clone https://github.com/yourusername/atom-encryption.git
cd atom-encryption
pip install .
```

## Usage

### Type Encode Decode Tools

The `TypeEncodeDecodeTools` module provides utilities for various type conversions, such as integer lists to strings, bytes to floats, and more.

```python
from atom_encryption.type_encode_decode_tools import TypeEncodeDecodeTools

tools = TypeEncodeDecodeTools()

# Example 1: Integer list to string and back
int_list = [72, 101, 108, 108, 111]
string = tools.int_list_to_str(int_list)
print("String:", string)  # Output: "Hello"
print("Back to Integer List:", tools.str_to_int_list(string))  # Output: [72, 101, 108, 108, 111]

# Example 2: Float to bytes and back
float_value = 12.34
float_bytes = tools.float_to_bytes(float_value)
print("Bytes:", float_bytes)
print("Float:", tools.bytes_to_float(float_bytes))

# Example 3: Hex string format to bytes
byte_data = b"Hello"
formatted_hex = tools.bytes_to_hex_string_format(byte_data)
print("Hex String Format:", formatted_hex)  # Output: "\x48\x65\x6c\x6c\x6f"
print("Bytes:", tools.hex_string_format_to_bytes(formatted_hex))  # Output: b"Hello"

# Example 4: Integer to integer list with MSB ordering
integer_value = 123456
int_list = tools.int_to_int_list(integer_value, specified_length=4, order="msb")
print("Integer List (MSB):", int_list)  # Output: [0, 1, 226, 64]
print("Back to Integer:", tools.int_list_to_int(int_list, "msb"))  # Output: 123456
```

### Error Detection Tools

```python
from atom_encryption.error_detection_tools import ErrorDetectionTools

# Example: BCC
bcc = ErrorDetectionTools.BCC.generate(b"123456789")
print("BCC:", bcc)
```

### Irreversible Encryption Tools

```python
from atom_encryption.irreversible_encryption_tools import IrreversibleEncryptionTools

# Example: SHA-256 Hashing
hashed_data = IrreversibleEncryptionTools.Hash.hash_data("HelloWorld", algorithm="sha256")
print("SHA-256 Hash:", hashed_data)
```

### Reversible Encryption Tools

```python
from atom_encryption.reversible_encryption_tools import ReversibleEncryptionTools

# Example: AES Encryption
aes_tool = ReversibleEncryptionTools.AES()
aes_tool.generate_key()
key = aes_tool.load_key()
encrypted = aes_tool.encrypt_data("Hello AES", key)
decrypted = aes_tool.decrypt_data(encrypted, key)
print("Decrypted:", decrypted)
```

## Development

### Requirements

Before you begin, ensure you have the following installed:

- Python 3.8 or higher
- pip

Install the dependencies:

```bash
pip install -r requirements.txt
```

### Running Tests

To run the test, please clone the Github project and run the could below:
Github link: [atom_encryption](https://github.com/alfredzhang98/atom_sdk/tree/master/atom_encryption)

```bash
python -m unittest discover test
```

## Building and Uploading to PyPI

### Step 1: Install Build Tools

Make sure you have the required tools for building and uploading:

```bash
pip install build twine
```

### Step 2: Build the Package

Build the source distribution and wheel:

```bash
python -m build
```

This will generate the `dist/` folder containing `.tar.gz` and `.whl` files.

### Step 3: Upload to PyPI

Upload the package to PyPI using Twine:

```bash
twine upload dist/*
```

You will be prompted to enter your PyPI credentials. Once done, your package will be live on PyPI.
