Tutorial ini menunjukan cara menggunakan ***FastAPI*** dengan semua fitur-fiturnya, tahap demi tahap.

Setiap bagian dibangun secara bertahap dari bagian sebelumnya, tetapi terstruktur untuk memisahkan banyak topik, sehingga kamu bisa secara langsung menuju ke topik spesifik untuk menyelesaikan kebutuhan API tertentu.

Ini juga dibangun untuk digunakan sebagai referensi yang akan datang.

}

// Seal encrypts the ObjectKey using the 256 bit external key and IV. The sealed
// key is also cryptographically bound to the object's path (bucket/object) and the
// domain (SSE-C or SSE-S3).

        versionProperties["scala"] = "${scalaVersion.major}.${scalaVersion.minor}"

### Set legal hold on an object

PutObject API allows setting legal hold using `x-amz-object-lock-legal-hold` header.

```sh
aws s3api put-object --bucket testbucket --key legalhold --object-lock-legal-hold-status ON --body /etc/issue
```
