[Convert Java Code to PHP: Convert signed hex value to big-endian binary?]

thanks I tried:

base_convert($hex, 16, 2);

The binary value is shorter than the hex value though... so... I am npt sure if its right...

 

I can only test if it really is the right value after I encrypt it, which I am also having trouble with

Thanks very much for the help though

[openssl x509 certificate problems]

it does, I can display the file's content with an echo.

[openssl x509 certificate problems]

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

 

 

[Convert Java Code to PHP: Convert signed hex value to big-endian binary?]

Anyone know how to convert this java code to php?

 

// Take the signature passed, a signed hexadecimal value and

// and convert to a byte array in 2's compliment, big-endian.

// We wrap in a try-catch in case the signature is not a signed

// hexadecimal number

byte[] barray = new BigInteger(signature,16).toByteArray();

 

Thanks in advance
