A class to validate SSL certificates

Latest Version on Packagist MIT Licensed GitHub Workflow Status Quality Score StyleCI Total Downloads

The class provided by this package makes it incredibly easy to query the properties on an ssl certificate. We have three options for fetching a certficate. Here's an example: ```php use Spatie\SslCertificate\SslCertificate;

// fetch the certificate using an url $certificate = SslCertificate::createForHostName('spatie.be');

// or from a certificate file $certificate = SslCertificate::createFromFile($pathToCertificateFile);

// or from a string $certificate = SslCertificate::createFromString($certificateData);

$certificate->getIssuer(); // returns "Let's Encrypt Authority X3" $certificate->isValid(); // returns true if the certificate is currently valid $certificate->validFromDate(); // returns a Carbon instance Carbon $certificate->expirationDate(); // returns a Carbon instance Carbon $certificate->lifespanInDays(); // return the amount of days between validFromDate and expirationDate $certificate->expirationDate()->diffInDays(); // returns an int $certificate->getSignatureAlgorithm(); // returns a string $certificate->getOrganization(); // returns the organization name when available ```

Spatie is a webdesign agency based in Antwerp, Belgium. You'll find an overview of all our open source projects on our website.

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.

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);

You can also check the certificate on a different IP address using the same style.

php
SslCertificate::download()
   ->fromIpAddress($ipAddress)
   ->forHost($hostName);

If the given

ipAddress
is invalid
Spatie\SslCertificate\Exceptions\InvalidIpAddress
will be thrown.

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 certificate's organization

Returns the organization belonging to the certificate

$certificate->getOrganization(); // returns "Spatie BVBA"

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 SHA256 fingerprint

$certificate->getFingerprintSha256(); // returns a SHA256 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
