## Password hashing { #password-hashing }

"Hashing" means converting some content (a password in this case) into a sequence of bytes (just a string) that looks like gibberish.

Whenever you pass exactly the same content (exactly the same password) you get exactly the same gibberish.

But you cannot convert from the gibberish back to the password.

Si les mots de passe ne correspondent pas, nous renvoyons la même erreur.

#### Hachage de mot de passe { #password-hashing }

Le « hachage » signifie : convertir un contenu (un mot de passe, dans ce cas) en une séquence d'octets (juste une chaîne) qui ressemble à du charabia.

Chaque fois que vous fournissez exactement le même contenu (exactement le même mot de passe), vous obtenez exactement le même charabia.

	return subtle.ConstantTimeCompare([]byte(sig1), []byte(sig2)) == 1

## Execution of dependencies with `yield` { #execution-of-dependencies-with-yield }

The sequence of execution is more or less like this diagram. Time flows from top to bottom. And each column is one of the parts interacting or executing code.
