A class to validate SSL certificates

Latest Version on Packagist Software License Build Status Quality Score StyleCI Total Downloads

The class provided by this package makes it incredibly easy to query the properties on an ssl certificate. Here's an example:

use Spatie\SslCertificate\SslCertificate;

$certificate = SslCertificate::createForHostName('spatie.be');

$certificate->getIssuer(); // returns "Let's Encrypt Authority X3"
$certificate->isValid(); // returns true if the certificate is currently valid
$certificate->expirationDate(); // returns an instance of Carbon
$certificate->expirationDate()->diffInDays(); // returns an int
$certificate->getSignatureAlgorithm(); // returns a string

Installation

You can install the package via composer:

composer require spatie/ssl-certificate

Important notice

Currently this package does not check if the certificate is signed by a trusted authority. We'll add this check soon in a next point release.

Usage

You can create an instance of Spatie\SslCertificate\SslCertificate with this named constructor:

$certificate = SslCertificate::createForHostName('spatie.be');

You can use this fluent style to specify a specific port to connect to.

SslCertificate::download()
   ->usingPort($customPort)
   ->forHost($hostName);

If the given hostName is invalid Spatie\SslCertificate\Exceptions\InvalidUrl will be thrown.

If the given hostName is valid but there was a problem downloading the certifcate Spatie\SslCertificate\Exceptions\CouldNotDownloadCertificate will be thrown.

Getting the issuer name

$certificate->getIssuer(); // returns "Let's Encrypt Authority X3"

Getting the domain name

Returns the primary domain name for the certificate

$certificate->getDomain(); // returns "spatie.be"

Getting the certificate's signing algorithm

Returns the algorithm used for signing the certificate

$certificate->getSignatureAlgorithm(); // returns "RSA-SHA256"

Getting the additional domain names

A certificate can cover multiple (sub)domains. Here's how to get them.

$certificate->getAdditionalDomains(); // returns ["spatie.be", "www.spatie.be]

A domain name return with this method can start with * meaning it is valid for all subdomains of that domain.

Getting the fingerprint

$certificate->getFingerprint(); // returns a fingerprint for the certificate

Getting the date when the certificate becomes valid

$certificate->validFromDate(); // returns an instance of Carbon

Getting the expiration date

$certificate->expirationDate(); // returns an instance of Carbon

Determining if the certificate is still valid

Returns true if the current Date and time is between validFromDate and expirationDate.

$certificate->isValid(); // returns a boolean

You also use this method to determine if a given domain is covered by the certificate. Of course it'll keep checking if the current Date and time is between validFromDate and expirationDate.

$certificate->isValid('spatie.be'); // returns true;
$certificate->isValid('laravel.com'); // returns false;

Determining if the certificate is still valid until a given date

Returns true if the certificate is valid and if the expirationDate is after the given date.

$certificate->isValidUntil(Carbon::now()->addDays(7)); // returns a boolean

Determining if the certificate is expired

$certificate->isExpired(); // returns a boolean if expired
