## Features

* Disclaimer: *the zip-native cryptography is unsecure*
* Streamed file turned into a streamed zip
* Can be used password-less for a non-encrypted zip stream
* Or with a password to apply on-the-fly zipcrypto to the stream
* Retro-compatibility for py35 with writable ZipInfo port

## Install

```console
    $ pip install ziphyr
```

## Usage

```python
   from ziphyr import Ziphyr

   # init the Ziphyr object
   z = Ziphyr(b'infected')
   # z = Ziphyr() for crypto-less usage

   # prepare it for a specific file, from path or metadata directly
   z.from_filepath(filepath)

   # consume the generator to get the encrypted ziped chunk
   for k in z.generator(source):
       pass
```

## Test

```console
   $ python -m unittest -v tests/*.py
```
