OpenSSL::PKCS12

Defines a file format commonly used to store private keys with accompanying public key certificates, protected with a password-based symmetric key.

Attributes

ca_certs[R]
certificate[R]
key[R]

Public Class Methods

create(pass, name, key, cert [, ca, [, key_pbe [, cert_pbe [, key_iter [, mac_iter [, keytype]]]]]]) click to toggle source

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.

See the OpenSSL documentation for PKCS12_create().
