PHP library for creating self-signed certificates. No dependencies.

composer require sashabo/self-signed-certs

<?php

use SashaBo\SelfSignedCerts\CertificateGenerator;

$generator = new CertificateGenerator();
$generator
    ->setName('Some Name')
    ->setEmail('[email protected]')
    ->setAddress('CC', 'State or province', 'City')
    ->setOrganization('Organization', 'Department')
;

$pair = $generator->generate();
$pair->save('/etc/nginx/ssl/my.key', '/etc/nginx/ssl/my.crt');

generate(): CertificatePair

These settings are not necessary, you may use defaults in most cases:

setExpireDays(int $days): static - 3650 by default

setPrivateKeyBits(int $bits): static - 4096 by default

setPrivateKeyType(int $type): static - OPENSSL_KEYTYPE_RSA by default

setDigestAlgorithm(string $algorithm): static - AES-128-CBC by default

setOpenSslConfPath(string $path): static - /etc/ssl/openssl.cnf by default (standard path for Ubuntu and most of linuxes)

These settings override openssl.cnf settings:

setName(string $name): static

setEmail(string $email): static

setAddress(string $countryCode, string $stateOrProvince, string $city): static

setOrganization(string $name, string $unit): static

getPrivateKey(): \OpenSSLAsymmetricKey

getCertificate(): \OpenSSLCertificate

exportPrivateKey(?string $passPhrase = null): string

exportCertificate(): string

save(string $privateKeyPath, string $certPath, ?string $passPhrase = null): void
