Sie können jedoch nicht vom Kauderwelsch zurück zum Passwort konvertieren.

##### Warum Passwort-Hashing verwenden?

Wenn Ihre Datenbank gestohlen wird, hat der Dieb nicht die Klartext-Passwörter Ihrer Benutzer, sondern nur die Hashes.

Der Dieb kann also nicht versuchen, die gleichen Passwörter in einem anderen System zu verwenden (da viele Benutzer überall das gleiche Passwort verwenden, wäre dies gefährlich).

- Choosing an erasure set for the object is decided during `PutObject()`, object names are used to find the right erasure set using the following pseudo code.

```go
// hashes the key returning an integer.
func sipHashMod(key string, cardinality int, id [16]byte) int {
        if cardinality <= 0 {
                return -1
        }
        sip := siphash.New(id[:])

            .createTestSuite());

    suite.addTest(
        SetTestSuiteBuilder.using(new ImmutableSetWithBadHashesGenerator())
            .named(ImmutableSetTest.class.getName() + ", with bad hashes")
            .withFeatures(
                CollectionSize.ANY,
                CollectionFeature.KNOWN_ORDER,
                CollectionFeature.ALLOWS_NULL_QUERIES)
            .createTestSuite());

        return this.username;

##### Porque usar hashing de senha

Se o seu banco de dados for roubado, o ladrão não terá as senhas em texto simples dos seus usuários, apenas os hashes.

Assim, o ladrão não poderá tentar usar essas mesmas senhas em outro sistema (como muitos usuários usam a mesma senha em todos os lugares, isso seria perigoso).
