Note: to use openssl_sign with ed25519 key in PHP 8.4 (and probably later versions), you need to explicitly pass 0 as algorithm identifier. Omitting this parameter will not work (because this parameter defaults to SHA1), but for some reason there is currently no OPENSSL_ALGO_xxxxx constant for the default signature algorithm. <?php $pkey = openssl_pkey_new(['private_key_type' => OPENSSL_KEYTYPE_ED25519]); if (openssl_sign('text', $sig, $pkey, 0)) { echo 'Signature successful: ' . bin2hex($sig); } else { echo 'Signature failed!'; } ?> ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 2a03:5800:f0c5:c580:7486:5209:2ec7:5a50) ---- Manual Page -- https://php.net/manual/en/function.openssl-sign.php Edit -- https://main.php.net/note/edit/130469 Del: integrated -- https://main.php.net/note/delete/130469/integrated Del: useless -- https://main.php.net/note/delete/130469/useless Del: bad code -- https://main.php.net/note/delete/130469/bad+code Del: spam -- https://main.php.net/note/delete/130469/spam Del: non-english -- https://main.php.net/note/delete/130469/non-english Del: in docs -- https://main.php.net/note/delete/130469/in+docs Del: other reasons-- https://main.php.net/note/delete/130469 Reject -- https://main.php.net/note/reject/130469 Search -- https://main.php.net/manage/user-notes.php
