I'm using a library that uses openssl_pkey_get_public, but it's returning false. It seems that openssl is enabled, and the key exists. Below are the few lines from the library I'm using, btw which I am debugging but cannot modify as it is not my code base:
protected function decrypt($encryptedData)
{
$publicKey = openssl_pkey_get_public($this->publicKey->getKeyPath());
$publicKeyDetails = @openssl_pkey_get_details($publicKey);
if ($publicKeyDetails === null) {
throw new \LogicException(
sprintf('Could not get details of public key: %s', $this->publicKey->getKeyPath())
);
}
.
.
.
I have the inserted the following debug code:
$keyPath = $this->publicKey->getKeyPath(); // returns file:///var/www/sso/website/storage/id_rsa.pub
var_dump(file_exists($keyPath)); // outputs true
var_dump(openssl_pkey_get_public($keyPath)); // returns false
Below shows the contents of $keyPath:
echo file_get_content($keyPath);

I had previously created the keys with the following command:
ssh-keygen -f storage/id_rsa -t rsa -N ''
Some additional info if it help:
$ php -i | grep openssl
openssl
Openssl default config => /usr/lib/ssl/openssl.cnf
openssl.cafile => no value => no value
openssl.capath => no value => no value
$ php -m | grep openssl
openssl
Is there any reason why this might be happening?
