openssl_spki_export - Exports a valid PEM formatted public key signed public key and challenge

SYNOPSIS

       string openssl_spki_export (string  &$spkac)

DESCRIPTION

	Exports PEM formatted public key from encoded signed public key and challenge

PARAMETERS

	      o $spkac
		- Expects a valid signed public key and challenge

RETURN VALUES

	Returns the associated PEM formatted public key or NULL on failure.

ERRORS
/EXCEPTIONS
	Emits an E_WARNING level error if an invalid argument is passed via the $spkac parameter.

EXAMPLES

       Example #1

	      openssl_spki_export(3) example

	       Extracts the associated PEM formatted public key or NULL on failure.

	      <?php
	      $pkey = openssl_pkey_new('secret password');
	      $spkac = openssl_spki_new($pkey, 'challenge string');
	      $pubKey = openssl_spki_export(preg_replace('/SPKAC=/', '', $spkac));

	      if ($pubKey) {
		  echo $pubKey;
	      }
	      ?>

       Example #2

	      openssl_spki_export(3) example from <keygen>

	       Extracts the associated PEM formatted public key issued from the <keygen> element

	      <?php
	      $spkac = openssl_spki_export(preg_replace('/SPKAC=/', '', $_POST['spkac']));
	      if ($spkac != NULL) {
		  echo $spkac;
	      } else {
		  echo "Extraction of pub key failed";
	      }
	      ?>
	      <keygen name="spkac" challenge="challenge string" keytype="RSA">

openssl_spki_new - Generate a new signed public key and challenge

SYNOPSIS

       string openssl_spki_new (resource  &$privkey, string  &$challenge, [int	$algorithm])

DESCRIPTION

	Generates a signed public key and challenge using specified hashing algorithm

PARAMETERS

	      o $privkey
		-$privkey  should  be  set  to	a private key that was previously generated by openssl_pkey_new(3) (or otherwise obtained from the
		other openssl_pkey family of functions). The corresponding public portion of the key will be used to sign the CSR.

	      o $challenge
		- The challenge associated to associate with the SPKAC

	      o $algorithm
		- The digest algorithm. See openssl_get_md_method().

RETURN VALUES

	Returns a signed public key and challenge string or NULL on failure.

ERRORS
/EXCEPTIONS
	Emits an E_WARNING level error if an unknown signature algorithm is passed via the $algorithm parameter.

EXAMPLES

       Example #1

	      openssl_spki_new(3) example

	       Generate a new SPKAC with the default digest (MD5)

	      <?php
	      $pkey = openssl_pkey_new('secret password');
	      $spkac = openssl_spki_new($pkey, 'testing');

	      if ($spkac !== NULL) {
		  echo $spkac;
	      } else {
		  echo "SPKAC generation failed";
	      }
	      ?>
