PHP中使用OpenSSL生成证书及加密解密
简介依赖于OpenSSL扩展/*加密解密*/function authcode($string, $operation = 'E') else{
openssl_public_encrypt($string,$data,$pu_key);//公钥加密
$data = base64_encode($data);
}
return $data;
}
/*生成证书*/
function exportOpenSSLFile(){
$config = array(
"digest_alg" => "sha512",
"private_key_bits" => 4096, //字节数 512 1024 2048 4096 等
"private_key_type" => OPENSSL_KEYTYPE_RSA, //加密类型
);
$res = openssl_pkey_new($config);
if($res == false) return false;
openssl_pkey_export($res, $private_key);
$public_key = openssl_pkey_get_details($res);
$public_key = $public_key["key"];
file_put_contents(DATA_PATH."/conf/cert_public.key",$public_key);
file_put_contents(DATA_PATH."/conf/cert_private.pem",$private_key);
openssl_free_key($res);
}
