How to Get Complete Issuer Name From Cert.pem In Php?

8 minutes read

To get the complete issuer name from a cert.pem file in PHP, you can follow the steps below:

  1. Read the contents of the cert.pem file using the file_get_contents function.
1
$certContents = file_get_contents("cert.pem");


  1. Create a new instance of the OpenSSLX509Certificate class and pass the cert.pem contents to its constructor.
1
$certificate = new OpenSSLX509Certificate($certContents);


  1. Use the getIssuerDN method to retrieve the issuer's distinguished name (DN) as a string.
1
$issuerName = $certificate->getIssuerDN();


  1. If you want to extract specific components from the issuer name, you can use the getComponents method to get an associative array of the issuer name components.
1
$issuerComponents = $certificate->getIssuerDN()->getComponents();


  1. Finally, you can access individual components of the issuer name using their keys in the $issuerComponents array.
1
2
3
4
$commonName = $issuerComponents['CN'];
$organization = $issuerComponents['O'];
$country = $issuerComponents['C'];
// and so on...


Remember to have the necessary OpenSSL extension enabled in your PHP installation for these functions to work properly.

How do I obtain the issuer name from a cert.pem file in PHP?

To obtain the issuer name from a cert.pem file in PHP, you can use the openssl_x509_parse function along with the issuer array key. Here's an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
// Read the PEM file contents
$pemData = file_get_contents('cert.pem');

// Parse the certificate
$certData = openssl_x509_parse($pemData);

// Get the issuer name
$issuerName = $certData['issuer']['CN'];

// Output the issuer name
echo $issuerName;


This code reads the contents of the cert.pem file, parses it using openssl_x509_parse, and then retrieves the Common Name (CN) of the issuer from the issuer key of the resulting array.


You can modify the code according to your needs if you want to extract other parts of the issuer's information from the certificate.


What is the easiest way to extract the issuer's complete name from a cert.pem file using PHP?

To extract the issuer's complete name from a cert.pem file using PHP, you can use the OpenSSL extension. Here's an example code snippet:

<?php
$certPath = 'path/to/cert.pem';

// Load the certificate file
$certContent = file_get_contents($certPath);

// Create an OpenSSL X.509 parsing resource
$certResource = openssl_x509_read($certContent);

// Get the issuer's name from the certificate
$issuerName = openssl_x509_parse($certResource)['issuer']['CN'];

// Clean up the resources
openssl_x509_free($certResource);

// Output the issuer's name
echo $issuerName;
?>


Make sure to replace 'path/to/cert.pem' with the actual path to your cert.pem file. The code reads the contents of the certificate file, creates an OpenSSL resource, extracts the issuer's name, and then releases the resources. Finally, it outputs the issuer's name.


How to get complete issuer name from cert.pem in PHP?

To get the complete issuer name from a cert.pem file in PHP, you can use the OpenSSL extension in PHP. Here's a step-by-step guide on how to achieve this:

  1. Load the contents of the cert.pem file into a variable:
1
2
$certFile = 'path/to/cert.pem';
$certContent = file_get_contents($certFile);


  1. Extract the certificate details using the openssl_x509_parse() function:
1
$certDetails = openssl_x509_parse($certContent);


This function parses the certificate and returns an associative array with different attributes.

  1. Get the issuer's complete name from the $certDetails array:
1
$issuerName = $certDetails['issuer']['name'];


The issuer's name can be accessed within the $certDetails array using the 'issuer' key, followed by the 'name' key.


That's it! Now the $issuerName variable will store the complete issuer name from the cert.pem file.


Note: Ensure that the OpenSSL extension is enabled in your PHP configuration for this to work.
