ArgumentCountError Thrown When Using openssl_public_encrypt and Other OpenSSL Functions

[alperenuzun]

Description

After migrating from Amazon Linux 2 to Ubuntu 22.04 — and upgrading OpenSSL from version 1.0.2 to 3.0.2 — I have encountered two recurring types of errors:

---

1. OpenSSL Encryption Method Errors (ArgumentCountError)

When calling the openssl_public_encrypt function, it seems the method signature has changed, resulting in errors such as:

openssl_public_encrypt() expects exactly 1 argument, 4 given
openssl_public_encrypt() expects exactly 2 arguments, 4 given
openssl_public_encrypt() expects at most 3 arguments, 4 given

Other methods also show similar inconsistencies:

openssl_pkey_get_private() expects at least 2 arguments, 1 given
openssl_pkey_get_private() expects exactly 1 argument, 1 given

While this may indicate changes in method signatures or internal validation logic, it's still unclear why different ArgumentCountError messages are thrown for the same method.

2. cURL Errors

cURL error 35: error:03000072:digital envelope routines::decode error

This error occurs intermittently, particularly during peak request times.

---

Error Frequency: 10–20 times per day (Not always)
OpenSSL Version: 3.0.9

Questions

• Has anyone else experienced similar issues after upgrading to OpenSSL 3.x and Ubuntu 22.04?
• Could this be related to the PHP version or its OpenSSL extension compatibility?

Any insights or suggestions would be greatly appreciated.

Can you try upgrading to PHP 8.1.32? Is this not available in Ubuntu 22.04 yet?

@alperenuzun Could you also clarify whether you're using JIT or any 3rd party extensions?

My apologies for the mistake; my PHP version is actually 8.1.2.

Below is the JIT output:

php -i |grep JIT
PCRE JIT Support => enabled
PCRE JIT Target => ARM-64 64bit (little endian + unaligned)
JIT => On

Additionally, here are the enabled modules:

I haven't attempted to upgrade to a newer PHP version yet. This is because the error is difficult to reproduce using a local image, and upgrading PHP in our production environment also presents challenges. Therefore, I would prefer to exhaust all troubleshooting steps with the current version first.

Considering this situation, do you believe upgrading is likely to fix the issue and is it a worthwhile step to consider despite the difficulty?

[iluuu1994]

8.1.2 is over 3 years old at this point. Chances are that this issue is already fixed, and thus any investigation to find the cause would be a waste of time. Hence, please upgrade first.

It would also be worth trying to disable the JIT (not PCRE JIT), as it can sometimes lead to issues (especially given how old this version is).
