class OpenSSL::PKCS12

定义了一种常用的文件格式，用于存储包含公钥证书的私钥，并使用基于密码的对称密钥进行保护。

常量

KEY_EX: MSIE 特定的 PKCS12 密钥使用扩展
KEY_SIG

属性

ca_certs[R]

certificate[R]

key[R]

create(pass, name, key, cert [, ca, [, key_pbe [, cert_pbe [, key_iter [, mac_iter [, keytype]]]]]]) 点击以切换源代码

参数¶ ↑

pass - 字符串
name - 描述密钥的字符串。
key - 任何 PKey。
cert - 一个 X509::Certificate。
- 证书的 public_key 部分必须包含有效的公钥。
- 必须填写 not_before 和 not_after 字段。
ca - 可选的 X509::Certificate 数组。
key_pbe - 字符串
cert_pbe - 字符串
key_iter - 整数
mac_iter - 整数
keytype - 表示 MSIE 特定扩展的整数。

任何可选参数都可以作为 nil 提供，以保留 OpenSSL 的默认值。

设置 MAC 参数并对 PKCS #12 结构生成 MAC。

此方法使用 HMAC 和原始 PKCS #12 中指定的 PKCS #12 特定的基于密码的 KDF。

另请参见 man page PKCS12_set_mac(3)。

在 3.3.0 版本中添加。
