|state|[int](../types/int.md) | Yes|State of the secret chat, 0 - yet not created, 1 - active, 2 - closed|
|is\_outbound|[Bool](../types/Bool.md) | Yes|True if chat was created by the current logged in user, false otherwise|
|ttl|[int](../types/int.md) | Yes|Current message TTL setting for the chat in seconds|
|key\_hash|[bytes](../types/bytes.md) | Yes|Hash of the current used key for comparison with the hash of the interlocutor's key. String of 36 bytes, which should be used to make a 12x12 square image with a color depth of 4. First 16 bytes should be used to make a central 8 * 8 square, left 20 bytes should be used to construct a border of width 2 around that square. -Alternatively first 32 bytes of the hash can be converted to hex and printed as 32 2-digit hex numbers.|
### Type: [SecretChat](../types/SecretChat.md)
### Example:
```
$secretChat = ['_' => 'secretChat', 'id' => int, 'user_id' => int, 'state' => int, 'is_outbound' => Bool, 'ttl' => int, 'key_hash' => 'bytes'];
```
[PWRTelegram](https://pwrtelegram.xyz) json-encoded version:
```
{"_": "secretChat", "id": int, "user_id": int, "state": int, "is_outbound": Bool, "ttl": int, "key_hash": "bytes"}
```
Or, if you're into Lua:
```
secretChat={_='secretChat', id=int, user_id=int, state=int, is_outbound=Bool, ttl=int, key_hash='bytes'}
```
