openssl_pkcs12_export — 将 PKCS#12 兼容证书存储文件导出到变量

说明

openssl_pkcs12_export(
    OpenSSLCertificate|string $certificate,
    string &$output,
    #[\SensitiveParameter] OpenSSLAsymmetricKey|OpenSSLCertificate|array|string $private_key,
    #[\SensitiveParameter] string $passphrase,
    array $options = []
): bool

openssl_pkcs12_export() 以 PKCS#12 文件格式将 certificate 导入到名为 output 的字符串变量中。

参数

x509

参见密钥／证书参数以获取有效值列表。

output

成功，该字符串将为 PKCS#12 格式。

private_key

PKCS#12 文件的私钥部分file，参见公/私钥参数获取更多可用列表。

passphrase

用来解锁 PKCS#12 文件的解密密码。

If your certificate is not password-protected, just use null or a blank string. Otherwise, this function won't work.

If you need to provide multiple additional certificates, the 'extracerts' argument needs to be an array with one certificate per element:
<?php
$args = array(
'extracerts' => array(
0 => '-----BEGIN CERTIFICATE----- cert1 ...',
1 => '-----BEGIN CERTIFICATE----- cert2 ...',
// ...
)
    );
?>

You can use this to prepare a PEM.

<?php
$pemChain = '...';
preg_match_all('/(-----BEGIN CERTIFICATE-----.*?-----END CERTIFICATE-----)/si', $pemChain, $matches);
$args = array('extracerts' => $matches[0]);
openssl_pkcs12_export($signed_csr, $cerificate_out, $private_key_resource, $passphrase, $args);
?>

in order to export a private key to pkcs12 format, the input certificate must contain both private and associated public key in PEM format ,  

-----BEGIN RSA PRIVATE KEY-----
-----END RSA PRIVATE KEY-----

-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----

else this function might return the following error "openssl_pkcs12_export(): cannot get cert from parameter 1"

If you want to include CA-Certificates in the PKCS12 it can be accomplished by using the $args parameter.
<?php
$args = array(
'extracerts' => $CAcert,
'friendly_name' => 'My signed cert by CA certificate'
);
openssl_pkcs12_export($signed_csr, $cerificate_out, $private_key_resource, $passphrase, $args);
?>
