How to check if installed OpenSSL version is >= 0.9.8k

Question

I have a PHP 5.x script which requires OpenSSL 0.9.8k or higher.

In regard to OpenSSL, I found the following two relevant constants:

OPENSSL_VERSION         


        

Answer 1

The source for version 0.9.8k has a constant OPENSSL_VERSION_NUMBER of 0x009080bf

<?php

if(OPENSSL_VERSION_NUMBER < 0x009080bf) {
    echo "OpenSSL Version Out-of-Date";
} else {
    echo "OpenSSL Version OK";
}

?>

Answer 2

If you like the one line command though:

php -r "echo OPENSSL_VERSION_NUMBER;"

Answer 3

printInfo() output should tell you if you have openSSL support
