数字证书有多种格式，其中一些常见的格式包括：

openssl x509 -outform der -in demo.pem -out demo.cer

转换得到的cer格式数字证书与从Charles导出的cer格式数字证书一致

openssl x509 -inform der -in demo.cer -out demo.pem

转换得到的pem格式数字证书与从Charles导出的pem格式数字证书一致

在移动设备上安装证书时，可能会导致证书文件名发生变化的原因有几个可能：

所以我们可以进行手机更改文件名的,将原文件名修改为<hash>.0

对于.pem证书

对于.cer证书

在 Android 系统中，证书的管理和解析是由 Android 的安全框架和 Keystore 系统来完成的。Android 系统中的证书管理主要涉及以下几个方面：

在 Android 系统中，证书的解析和使用通常涉及以下步骤：

总的来说，在 Android 系统中，证书的管理和使用是由安全框架、Keystore 系统和系统证书存储共同实现的。这些组件能够保障证书的安全性和可靠性，并在系统级别上提供安全的证书管理和使用功能。因此，当你将 .pem 格式的证书文件放入系统证书目录时，系统会自动将其转换为二进制格式的 .cer 格式的证书文件，以便系统能够更方便地处理和使用。这种转换通常是由系统的证书管理工具或者证书存储服务自动完成的，用户无需手动操作。

就会发现该文件已转换为cer二进制文件的数字证书

结果发现pem格式数字证书的安装，经过系统的证书安装程序,会将pem格式数字证书转化为cer格式数字证书。

抓包效果：

通过Move_Certificates-v1.9模块将用户证书目录下的证书转存到系统证书目录中去。

SSL证书报错,相对与用户证书抓包效果好了很多。

将证书推送到Move_Certificates模块目录下

对于.pem证书

对于.cer证书

把 -----BEGIN CERTIFICATE----- 到最后的这部分移动到开头
