Parameters¶ ↑

pass - string
name - A string describing the key.
key - Any PKey.
cert - A X509::Certificate.
- The public_key portion of the certificate must contain a valid public key.
- The not_before and not_after fields must be filled in.
ca - An optional array of X509::Certificate‘s.
key_pbe - string
cert_pbe - string
key_iter - integer
mac_iter - integer
keytype - An integer representing an MSIE specific extension.

Any optional arguments may be supplied as nil to preserve the OpenSSL defaults.
