RS256 segmentation fault

[riquebrenner]

Greetings! I am trying to use RSA but SF (segmentation fault) is occurring.

I am creating a private key with this command:
"openssl genpkey -algorithm RSA -out private_key.pem -pkeyopt rsa_keygen_bits: 1024"

and a public key with this command:
"openssl rsa -pubout -in private_key.pem -out public_key.pem"

and I'm using these functions:

$privateKey = file_get_contents ('private_key.pem');
$publicKey = file_get_contents ('public_key');
$retVal['Bearer'] = jwt_encode($payload, $privateKey, 'RS256');
$open_token = jwt_decode ($token, $publicKey, ['algorithm' => 'RS256']);

I walked step-by-step in the code, the values are generated, but further ahead in the code happens the segmentation failure. Am I doing something wrong?
I'm using CentOS 7, PHP 7.3 and mariaDB through the mysqli module.
When I use HS256 it runs ok.

I did not reproduce this problem in PHP 7.3.

What's version of openssl?

[riquebrenner]

Good morning, the version is 1.0.2k

[cdoco]

openssl 1.0.2k seems to be problematic, and it is recommended to upgrade to version 1.1.0j or more.

Excuse me, I am now using a Debian 9.8 server with apache 2.4.25, php 7.3.3 and the JWT library compiled with openssl 1.1.1b and I still get segmentation failure messages. I'm studying how to put the jwt library in debug mode so I get a stack-trace and send it to verify. Do you have any suggestion?
