Dans ce cadre, j'ai dû étudier, tester et utiliser de nombreuses alternatives.

L'histoire de **FastAPI** est en grande partie l'histoire de ses prédécesseurs.

Comme dit dans la section [Alternatives](alternatives.md){.internal-link target=\_blank} :

## Let's Encrypt { #lets-encrypt }

Before Let's Encrypt, these **HTTPS certificates** were sold by trusted third parties.

The process to acquire one of these certificates used to be cumbersome, require quite some paperwork and the certificates were quite expensive.

Como parte de eso, necesitaba investigar, probar y usar muchas alternativas.

La historia de **FastAPI** es en gran parte la historia de sus predecesores.

Como se dice en la sección [Alternativas](alternatives.md){.internal-link target=_blank}:

<blockquote markdown="1">

				if partErr == checkPartFileCorrupt {

			}
		}
		return false, false, nil
	}
	return false, false, erErr

	for i1, size := range sizes[partStart:] {
		i := partStart + i1
		if endOffset < cumulativeSum+size {
			partEnd = i
			break
		}
		cumulativeSum += size
		encPartSize, _ := sio.EncryptedSize(uint64(size))
		encCumulativeSum += int64(encPartSize)
	}
	// partEnd is always found in the loop above, because off and
	// length are validated.

import okhttp3.internal.UTC

Probablemente harías esto solo una vez, la primera vez, al configurar todo.

/// tip | Consejo

Esta parte del Nombre de Dominio es mucho antes de HTTPS, pero como todo depende del dominio y la dirección IP, vale la pena mencionarlo aquí.

Ahora centrémonos en todas las partes realmente de HTTPS.
