```

**Note**: the session cookie structure must be a valid python dictionary

### Decode

With secret key:

```
$ python{2,3} flask_session_cookie_manager{2,3}.py decode -c 'eyJudW1iZXIiOnsiIGIiOiJNekkyTkRFd01ETXhOVEExIn0sInVzZXJuYW1lIjp7IiBiIjoiWVdSdGFXND0ifX0.DE2iRA.ig5KSlnmsDH4uhDpmsFRPupB5Vw' -s '.{y]tR&sp&77RdO~u3@XAh#TalD@Oh~yOF_51H(QV};K|ghT^d'
{u'username': 'admin', u'number': '326410031505'}
```

Without secret key (less pretty output):

```
$ python{2,3} flask_session_cookie_manager{2,3}.py decode -c 'eyJudW1iZXIiOnsiIGIiOiJNekkyTkRFd01ETXhOVEExIn0sInVzZXJuYW1lIjp7IiBiIjoiWVdSdGFXND0ifX0.DE2iRA.ig5KSlnmsDH4uhDpmsFRPupB5Vw'
