Beschreibung
Ein Record, der den SHA-1-Hashtyp implementiert.
THashSHA1 stellt Methoden wie die folgenden bereit:
- Update: Aktualisiert den Hashwert mit den angegebenen Daten.
- GetHashString: Gibt den Hashwert des angegebenen Strings zurück.
- GetHashStringFromFile: Gibt den Hashwert der angegebenen Datei zurück.
- GetHMAC: Gibt eine String-Repräsentation zurück, die der HMAC-Authentifizierung (Hash-Based Message Authentication Code) zugeordnet ist.
