php读取der格式证书乱码解决方法_php实例

遇到的问题:

我的项目需要用到应用der格式的证书公钥及RSA算法来验签相关签名,PHP关于RSA算法不是很懂,手头上有Java和.net两种语言的实现,PHP实现甚感吃力。

小伙伴们的解答:

这个证书有他自己相应的编码,首先要找到这个,然后在用php读,设置对应的编码就好了。另外你如果是直接echo出证书内容的话,在那之前最好用标签编码一下,否则他其实没乱码,只是你浏览器无法识别而已。还要注意你php那个文件的编码哦~~

直接读取当然是乱码了,der密钥证书本来就是二进制编码或者BASE64编码的文件,php可以用openssl_x509_parse函数来解析:

 
<&#63;php
$cert = file_get_contents('filename.crt');
$ssl = openssl_x509_parse($cert);
var_dump($ssl);
&#63;>
Copy after login

以上所述就是本文的全部内容了,希望大家能够喜欢。
