Description
Enregistrement qui implémente le type de hachage SHA-1.
THashSHA1 fournit des méthodes comme :
- Update : met à jour la valeur de hachage avec les données fournies.
- GetHashString : renvoie la valeur de hachage de la chaîne fournie.
- GetHashStringFromFile : renvoie la valeur hash du fichier fourni.
- GetHMAC : renvoie une représentation chaîne associée avec l'authentification HMAC (code d'authentification de message basé sur le hachage).
