[英]Digital signature in PHP
Could someone please explain how to implement a "digital signature" in PHP. 有人可以解释一下如何在PHP中实现“数字签名”。 I've tried hard to find an answer myself, but have had little success so far.
我一直在努力寻找答案,但到目前为止收效甚微。
I'll give you a pro-forma answer since you have an overly unspecific inquiry anyway: 无论如何,我都会给您一个形式上的答案,因为您的查询过于具体:
file_put_contents("/tmp/document", $text);
exec("gpg --clearsign /tmp/document");
$signed_text = file_get_contents("/tmp/document.asc");
Usually you want to add a --keyring
option too. 通常,您也想添加
--keyring
选项。 For more complex operations you can use the PHP extension for GPG as shown in this article: http://devzone.zend.com/article/3753 对于更复杂的操作,您可以使用GPG的PHP扩展,如本文所示: http : //devzone.zend.com/article/3753
