Parameter

pass - String
name - Ein String, der den Schlüssel beschreibt.
key - Ein beliebiger PKey.
cert - Ein X509::Certificate.
- Der public_key-Teil des Zertifikats muss einen gültigen öffentlichen Schlüssel enthalten.
- Die Felder not_before und not_after müssen ausgefüllt sein.
ca - Ein optionales Array von X509::Certificates.
key_pbe - String
cert_pbe - String
key_iter - Integer
mac_iter - Integer
keytype - Eine Ganzzahl, die eine MSIE-spezifische Erweiterung darstellt.

Alle optionalen Argumente können als nil übergeben werden, um die OpenSSL-Standardwerte beizubehalten.

Setzt MAC-Parameter und generiert MAC über die PKCS #12-Struktur.

Diese Methode verwendet HMAC und den PKCS #12-spezifischen passwortbasierten KDF, wie im ursprünglichen PKCS #12 spezifiziert.
