### 3. Note ### 3. Compression + Encryption
- Already compressed objects are not fit for compression since they do not have compressible patterns. Such objects do not produce efficient [`LZ compression`](https://en.wikipedia.org/wiki/LZ77_and_LZ78) which is a fitness factor for a lossless data compression. Below is a list of common files and content-types which are not suitable for compression. Combining encryption and compression is not safe in all setups.
This is particularly so if the compression ratio of your content reveals information about it.
See [CRIME TLS](https://en.wikipedia.org/wiki/CRIME) as an example of this.
Therefore, compression is disabled when encrypting by default, and must be enabled separately.
Consult our security experts on [SUBNET](https://min.io/pricing) to help you evaluate if
your setup can use this feature combination safely.
To enable compression+encryption use:
```bash
~ mc admin config set myminio compression allow_encryption=on
```
Or alternatively through the environment variable `MINIO_COMPRESS_ALLOW_ENCRYPTION=on`.
### 4. Excluded Types
- Already compressed objects are not fit for compression since they do not have compressible patterns.
Such objects do not produce efficient [`LZ compression`](https://en.wikipedia.org/wiki/LZ77_and_LZ78)
which is a fitness factor for a lossless data compression.
Pre-compressed input typically compresses in excess of 2GiB/s per core,
so performance impact should be minimal even if precompressed data is re-compressed.
Decompressing incompressible data has no significant performance impact.
