É comum que cada provedor de autenticação nomeie os seus fluxos de forma diferente, para torná-lo parte de sua marca.

Mas no final, eles estão implementando o mesmo padrão OAuth2.

///

O **FastAPI** inclui utilitários para todos esses fluxos de autenticação OAuth2 em `fastapi.security.oauth2`.

## `Security` em docoradores de `dependências`

	for _, sum := range e.Checksums {
		if sum.PartNumber == partNumber {
			// Return the checksum
			return sum
		}
	}
	return ChecksumInfo{Algorithm: DefaultBitrotAlgorithm}
}

// ShardFileSize - returns final erasure size from original size.
func (e ErasureInfo) ShardFileSize(totalLength int64) int64 {
	if totalLength == 0 {
		return 0
	}
	if totalLength == -1 {
		return -1
	}
	numShards := totalLength / e.BlockSize

Essa prática é tão comum que possui um nome, essas variáveis de ambiente normalmente são colocadas em um arquivo `.env`, e esse arquivo é chamado de "dotenv".

/// dica

Um arquivo iniciando com um ponto final (`.`) é um arquivo oculto em sistemas baseados em Unix, como Linux e MacOS.

Mas um arquivo dotenv não precisa ter esse nome exato.

Then APIStar stopped to exist as a server and Starlette was created, and was a new better foundation for such a system. That was the final inspiration to build **FastAPI**.

I consider **FastAPI** a "spiritual successor" to APIStar, while improving and increasing the features, typing system, and other parts, based on the learnings from all these previous tools.
