openssl_csr_new — Generates a CSR
Описание
$dn
, resource &$privkey
[, array $configargs
[, array $extraattribs
]] )
openssl_csr_new() generates a new CSR (Certificate Signing Request)
based on the information provided by dn, which represents the
Distinguished Name to be used in the certificate.
Замечание: Для корректной работы этой функции должен существовать правильный openssl.cnf. Для более подробной информации смотрите замечания под разделом установки.
Список параметров
-
dn -
The Distinguished Name to be used in the certificate.
-
privkey -
privkeyshould be set to a private key that was previously generated by openssl_pkey_new() (or otherwise obtained from the other openssl_pkey family of functions). The corresponding public portion of the key will be used to sign the CSR. -
configargs -
By default, the information in your system openssl.conf is used to initialize the request; you can specify a configuration file section by setting the config_section_section key of
configargs. You can also specify an alternative openssl configuration file by setting the value of the config key to the path of the file you want to use. The following keys, if present inconfigargsbehave as their equivalents in the openssl.conf, as listed in the table below.Configuration overrides configargskeytype openssl.conf equivalent description digest_alg string default_md Selects which digest method to use x509_extensions string x509_extensions Selects which extensions should be used when creating an x509 certificate req_extensions string req_extensions Selects which extensions should be used when creating a CSR private_key_bits integer default_bits Specifies how many bits should be used to generate a private key private_key_type integer none Specifies the type of private key to create. This can be one of OPENSSL_KEYTYPE_DSA,OPENSSL_KEYTYPE_DHorOPENSSL_KEYTYPE_RSA. The default value isOPENSSL_KEYTYPE_RSAwhich is currently the only supported key type.encrypt_key boolean encrypt_key Should an exported key (with passphrase) be encrypted? encrypt_key_cipher integer none One of cipher constants. -
extraattribs -
extraattribsis used to specify additional configuration options for the CSR. Bothdnandextraattribsare associative arrays whose keys are converted to OIDs and applied to the relevant part of the request.
Возвращаемые значения
Returns the CSR.
Примеры
Пример #1 Creating a self-signed-certificate
<?php
// 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.
$dn = array(
"countryName" => "UK",
"stateOrProvinceName" => "Somerset",
"localityName" => "Glastonbury",
"organizationName" => "The Brain Room Limited",
"organizationalUnitName" => "PHP Documentation Team",
"commonName" => "Wez Furlong",
"emailAddress" => "wez@example.com"
);
// Generate a new private (and public) key pair
$privkey = openssl_pkey_new();
// Generate a certificate signing request
$csr = openssl_csr_new($dn, $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, $privkey, 365);
// Now you will want to preserve your private key, CSR and self-signed
// cert so that they can be installed into your web server, mail server
// or mail client (depending on the intended use of the certificate).
// This example shows how to get those things into variables, but you
// can also store them directly into files.
// Typically, you will send the CSR on to your CA who will then issue
// you with the "real" certificate.
openssl_csr_export($csr, $csrout) and var_dump($csrout);
openssl_x509_export($sscert, $certout) and var_dump($certout);
openssl_pkey_export($privkey, $pkeyout, "mypassword") and var_dump($pkeyout);
// Show any errors that occurred here
while (($e = openssl_error_string()) !== false) {
echo $e . "\n";
