[英]OpenSSL TimeStampQuery equivalent in PHP
I'm trying to create a TimeStampQuery (tsq) to use with the Time-Stamp Protocol . 我正在尝试创建一个TimeStampQuery(tsq)以与Time-Stamp Protocol一起使用 。 In order to achieve this, I'm using the following OpenSSL terminal command: 为了实现这一点,我使用以下OpenSSL终端命令:
openssl ts -query -data input_file.xml -no_nonce -sha512 -out request.tsq
Can the OpenSSL PHP extension generate Time-Stamp Queries without the need of an external executable? OpenSSL PHP扩展可以在不需要外部可执行文件的情况下生成时间戳查询吗? If so, how? 如果是这样,怎么办?
I finally found a feasible alternative written entirely in PHP: https://github.com/vakata/asn1 我终于找到了完全用PHP编写的可行替代方法: https : //github.com/vakata/asn1
It is designed to create and parse Abstract Syntax Notation One data structures, but comes with a specific class for generating Time-Stamp Queries which is really straight-forward to use: 它旨在创建和解析“ 抽象语法表示法”一个数据结构,但附带一个用于生成时间戳查询的特定类,该类确实很容易使用:
$message = "Hello World";
$tsq = \vakata\asn1\Timestamp::generateRequestFromData($message);
// Send TSQ to an authorized entity
The documentation related to the previous method can be found here . 与以前的方法有关的文档可以在这里找到。
