## Description
This library provides fast C implementations of the E2E CRC algorithms and E2E profiles.
Currently, all relevant CRC algorithms are available in module `e2e.crc`
but only E2E profiles 1, 2, 4, 5 and 7 are available.
If you provide example data for the other profiles I would try to implement them, too.
## Installation
```console
pip install autosar-e2e
```
## Usage
### CRC example
```python3
import e2e
crc: int = e2e.crc.calculate_crc8_h2f(b"\x00\x00\x00\x00")
```
### E2E Profile 2
```python3
import e2e
# create data
data = bytearray(b"\x00" * 8)
length = len(data) - 1
data_id_list = b"\x00" * 16
# increment counter and calculate CRC inplace
e2e.p02.e2e_p02_protect(data, length, data_id_list, increment_counter=True)
# check CRC
crc_correct: bool = e2e.p02.e2e_p02_check(data, length, data_id_list)
```
## Test
```console
pip install pipx
pipx run tox
```
## Build
```console
pip install pipx
pipx run build
pipx run twine check dist/*
```
