openssl x509 certificate problems

[sookyboo]

I have a .cer file (generated from a jsp server I think).

 

I need to extract it's public key and use the public key to encrypt a value...

 

I get these errors:

Warning: openssl_x509_read() [function.openssl-x509-read]: supplied parameter cannot be coerced into an X509 certificate! in /public_html/test/cert.php on line 26

 

Warning: openssl_x509_free() expects parameter 1 to be resource, string given in /public_html/test/cert.php on line 34

 

    $fp = fopen("/home/x.cer", "r");

    $cert = fread($fp, 8192);

 

    fclose($fp);

openssl_x509_read( $cert);

$data = openssl_x509_parse($cert);

 

print_r($data);

 

openssl_x509_free( $cert );

 

 

Any ideas what is wrong...

Starting to get frustrated...

Thanks in advance

check if the file you're trying to open really exist!

Hi , it's my fisrt post in here, I hope this will help.

 

2 Do:

 

1. Generate a *.PEM certificate (Privacy Enhanced Mail) via Openssl command:

 

openssl pkcs12 -in  YOUR_pkcs12_certificate.pfx -out YOUR_NEW_CERTIFICATE.pem

 

2.The source code of PHP must be compiled with openssl option:

 

./configure --with-openssl=/usr

 

 

3.

<?php

 

$cert = file_get_contents("OUR_NEW_CERTIFICATE.pem");

$ssl = openssl_x509_parse($cert);

print_r($ssl);

?>

 

4. Cheers

I had the same issue and it turned out to be UTF-8 BOM.

In case you don't knoew what it means - it's 2 hidden characters at the beginning of a file that indicates it is encoded with UTF-8.

Notepad and other applications put it there by default.

To remove it:

If the file has only english characters (like certificates should have) - Open the file with notepad and click file>save as.

In the 'encoding' field select 'ANSI', and save the file.

 

Another option is to use HEX editor (I use xvi32 - free and good), and delete the first 2 characters.

 

I hope this helps someone...
