php openssl是否与perl等效?

以下代码的Perl中创建自签名证书的等效示例是什么?

我所拥有的一切都是crypt::openssl::rsa(如果有其他模块,请告诉我,以便我可以验证它是否可用或是否可以安装,因为我不是管理员/所有者,并且由于权限问题无法自行安装),我在文档中没有找到有关如何实现这类模块的信息…我确实希望尽可能避免使用命令行命令,但如果这是创建此命令的最后一个方法,就不要使用命令行命令…

<?php
// The certificate password
$passphrase = "some random password";

// Fill in data for the distinguished name to be used in the cert
// You must change the values of these keys to match your name and
// company, or more precisely, the name and company of the person/site
// that you are generating the certificate for.
// For SSL certificates, the commonName is usually the domain name of
// that will be using the certificate, but for S/MIME certificates,
// the commonName will be the name of the individual who will use the
// certificate.
$certificateInfo = array(
    "countryName" => "UK",
    "stateOrProvinceName" => "England",
    "localityName" => "London",
    "organizationName" => "blabla",
    "organizationalUnitName" => "Bla bla Developer's Team",
    "commonName" => "blabla.com",
    "emailAddress" => "support@blabla.com"
);

$configargs = array(
    'digest_alg' => 'sha1',
    'private_key_bits' => 1024,
    'private_key_type' => OPENSSL_KEYTYPE_RSA,
    'encrypt_key' => true
    );

// Generate a new private (and public) key pair
$privkey = null;

// Generate a certificate signing request
$csr = openssl_csr_new($certificateInfo, $privkey);

// You will usually want to create a self-signed certificate at this
// point until your CA fulfills your request.
// This creates a self-signed cert that is valid for 365 days
$sscert = openssl_csr_sign($csr, null, $privkey, 365, $configargs);//, $configArgs

// Now you will want to preserve your private key, CSR and self-signed
// cert so that they can be installed into your web server, mail server
// or mail client (depending on the intended use of the certificate).
// This example shows how to get those things into variables, but you
// can also store them directly into files.
// Typically, you will send the CSR on to your CA who will then issue
// you with the "real" certificate.
openssl_csr_export($csr, $csrout);
openssl_x509_export($sscert, $certout);
openssl_pkey_export($privkey, $pkeyout, $passphrase);
