This is not by chance, the whole framework was built around that design.

And it was thoroughly tested at the design phase, before any implementation, to ensure it would work with all the editors.

There were even some changes to Pydantic itself to support this.

## Auto Encryption

Auto-Encryption is useful when MinIO administrator wants to ensure that all data stored on MinIO is encrypted at rest.

### Using `mc encrypt` (recommended)

	// FileNameFunc must ensure collisions in filenames do not occur.

	// may fall on the same timestamp.
	// Eg.
	// 	2020-03-28_15-00-945-<random-hash>.log
