openssl_verify
openssl_verify & Verify signature
Description
int openssl_verify
( string $data
, string $signature
$pub_key_id
$signature_alg = OPENSSL_ALGO_SHA1
Parameters
The string of data used to generate the signature previously
A raw binary string, generated by
or similar means
pub_key_id
- a key, returned by
- a PEM formatted key, example, &-----BEGIN PUBLIC KEY-----
MIIBCgK...&
signature_alg
- one of these .
- a valid string returned by
example, &sha1WithRSAEncryption& or &sha512&.
Return Values
Returns 1 if the signature is correct, 0 if it is incorrect, and
-1 on error.

- Generate signature
A note about the openssl_verify() (and some of the other functions).& The public key comes from a certificate in any of the support formats (as the example shows, use openssl_get_publickey() to get the resource id).& But after some trial and error I found the signature string MUST BE BINARY.& While no error occurs, passing a base64-formatted signature string (PEM format?), you simply get a mismatch.& When I did the base64 decode myself, the verify returned a match (return value 1).& You can simply drop the begin/end lines and take the output of the 'base64_decode()' function.
I spent days scouring the php openssl documentation trying to figure out how to do what sounds like a simple task - given two PEM encoded certificates, is one the signer of the other?& Nowhere in the openssl_verify() documentation or comments is it explained where to obtain the signature of an existing certificate.& The openssl_x509_parse() function looked promising, but it is an unstable API that may change.I had to write my own code to determine if one cert signed another, it is located here: In a nutshell here is what I learned...The signature data in a signed X.509 certificate contains DER formatted data about the signature that is encrypted with the signers public key.& The data contains a hash of the original subject certificate and information about what encryption algorithm was used to create the signature.So you need to get this signature data and a copy of the original certificate with the issuer and signature sequences removed.& Hash a copy of the original certificate (sans issuer/signature sequences) with the same algorithm the issuer used and if the hashes match, you have the issuer cert that signed the certificate.
I've finally found a way to verify signature. Sample in the documentation doesn't work. Code bellow DOES work :)&?php$fp = fopen("path/file.pem", "r");$cert = fread($fp, 8192);fclose($fp);$ok = openssl_verify($data, $signature, $cert);if ($ok == 1) {& & echo "good";} elseif ($ok == 0) {& & echo "bad";} else {& & echo "ugly, error checking signature";}?&
openssl_verify() is populating openssl_error_string() even on false. When openssl_verify() returns 0, openssl_error_string() is populated with 1.I spent lot of time to understand, while my next call to openssl was failing with checks for error.&?php$c = file_get_contents($filename);$publicKey = openssl_pkey_get_public($c);$result = openssl_verify('freedom', 'someirrelevantnosign', $publicKey);$error = "";while ($msg = openssl_error_string() !== false) {& & $error .= $msg;}if (!empty($error)) {& & echo $error; }
Anbybody trying to get a Win32 CryptoAPI based digital signature component to work with the openssl_verify() function should be aware that the CryptoAPI PKCS1 (RSA) method uses bytes in reverse order while the openssl_verify() method expects a correctly formatted PKCS1 digital signature (as should be). I learned this the hard way and it took me some time to dig this out. A simple solution in VBScript to reverse the byte order:
N = Len(Blob.Hex)
' reverse bytes in the signature using Hex format
For i = 1 To N - 1 Step 2
& & s = Mid(Blob, i, 2) & s
s contains the digital signature in reverse order. Blob is an arbitrary binary container.
Send the signature off in Hex format and use a hex2bin method in PHP to convert to the correct format for openssl_verify(), i.e.
function hex2bin($data) {
& & $len = strlen($data);
& & return pack("H" . $len, $data);
That's it, hope it helps out. BTW I used ASPEncrypt to toy around with on Win32 platform. Works only with Internet Explorer but you could also use a Java applet and have none of the abovementioned problems :-)
You can actually use the public key as third parameter and not the certificate.If you can't make it work, make sure that :1) Your public key is well formatted. It seems that it must have the ----BEGIN PUBLIC KEY---- and ----END PUBLIC KEY----2) Your signature is in binary format. You can use the php base64_decode for this.
