Ich versuche, mit den folgenden Funktionen zu verschlüsseln und zu entschlüsseln. Dies führt jedoch zu einem schlechten Auffüllfehler.

Wenn ich setzePaddingMode zuNone Es werden einige alphanumerische Zeichen und zufällige Symbole in Log zurückgegeben.

Möglicherweise fehlt etwas an der richtigen Struktur:

Chiffre Rijndael (AES)Blockgröße 128 Bit (16 Byte)Modus CBC-Schlüssel (Cipher Block Chaining)MD5-Hash-PassphraseIV Wie der SchlüsselDatenkodierung Base64-ZeichenUTF-8-Codierung

Jede Hilfe zur Behebung dieses Fehlers und jede Unterstützung bei der Sicherstellung, dass die oben genannte Struktur eingehalten wird, wäre sehr dankbar! Vielen Dank
