note 108951 added to function.openssl-pkey-new

Getting the public key corresponding to a particular private key, through the methods provided for by OpenSSL, is a bit cumbersome. An easier way to do it is to use phpseclib, a pure PHP RSA implementation: <?php include('Crypt/RSA.php'); $rsa = new Crypt_RSA(); $rsa->loadKey('...'); $privatekey = $rsa->getPrivateKey(); $publickey = $rsa->getPublicKey(); ?> Doesn't require any extensions be installed. It'll use bcmath or gmp if they're available, for speed, but doesn't even require those. ---- Server IP: 69.147.83.197 Probable Submitter: 72.48.140.134 ---- Manual Page -- http://www.php.net/manual/en/function.openssl-pkey-new.php Edit -- https://master.php.net/note/edit/108951 Del: integrated -- https://master.php.net/note/delete/108951/integrated Del: useless -- https://master.php.net/note/delete/108951/useless Del: bad code -- https://master.php.net/note/delete/108951/bad+code Del: spam -- https://master.php.net/note/delete/108951/spam Del: non-english -- https://master.php.net/note/delete/108951/non-english Del: in docs -- https://master.php.net/note/delete/108951/in+docs Del: other reasons-- https://master.php.net/note/delete/108951 Reject -- https://master.php.net/note/reject/108951 Search -- https://master.php.net/manage/user-notes.php
