    openssl_pkey_get_private

    (PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)

    openssl_pkey_get_private — 获取私钥

    说明

    openssl_pkey_get_private(OpenSSLAsymmetricKey|OpenSSLCertificate|array|string $private_key, ?string $passphrase = null): OpenSSLAsymmetricKey|false

    openssl_pkey_get_private() 解析 private_key 供其他函数使用。

    参数

    private_key

    private_key 可以是如下密钥之一：

    1. 如下格式的字符串 file://path/to/file.pem。该文件必须包含 PEM 编码的证书或者私钥 (可能都包含了).
    2. 一个 PEM 格式的私钥。

    passphrase

    如果指定的密钥已被加密了(受密码保护)，可选参数 passphrase 是必须要的。

    返回值

    成功时现在返回 OpenSSLAsymmetricKey 实例，失败时返回 false。

    更新日志

    版本 说明
    8.0.0 成功时，此函数现在返回 OpenSSLAsymmetricKey 实例；之前返回类型 OpenSSL key 的 resource。
    8.0.0 private_key 现在接受 OpenSSLAsymmetricKey 或 OpenSSLCertificate 实例；之前接受类型 OpenSSL key 或 OpenSSL X.509 的 resource。
    8.0.0 passphrase 现在可为 null。

    It's actually "file://key.pem" when you want to give a relative path using unix systems. It will be three '/' in case of absolute path (e.g "file:///home/username/..."). But this path consists of two '/' originated from "file://" and one '/' from the fact that home is a subfolder of the unix filesystem's root directory ("/home/username/..."). This two part will be concatenated and you will get three '/' characters following each other.

    So you only have to concatenate "file://" with an existing path string in every case.

    Hi.

    If this function not work with pathname try with a file_get_contents of a key file.
