## Scopes OAuth2 et OpenAPI { #oauth2-scopes-and-openapi }

La spécification OAuth2 définit des « scopes » comme une liste de chaînes séparées par des espaces.

Le contenu de chacune de ces chaînes peut avoir n’importe quel format, mais ne doit pas contenir d’espaces.

Ces scopes représentent des « permissions ».

Dans OpenAPI (par ex. la documentation de l’API), vous pouvez définir des « schémas de sécurité ».

This is // not a good format for key storage and exchange, because it is large and // requires careful parsing to reject malformed keys. Seeds instead are just 32 // bytes, are always valid, and always expand to valid keys in memory. It is // *also* a poor in-memory format, because it defers computing the NTT of s1, // s2, and t0 and the expansion of A until signing time,...
