应该可以解密，参考这个链接432K9s2c8@1M7s2y4Q4x3@1q4Q4x3V1k6Q4x3V1k6Y4K9i4c8Z5N6h3u0Q4x3X3g2U0L8$3#2Q4x3V1k6K6N6r3g2$3k6g2)9J5k6r3#2Q4x3X3c8Z5j5i4W2Q4x3V1k6r3K9h3I4@1k6i4u0Q4x3X3c8o6M7Y4W2H3N6r3)9`.

兼容性

v2.00以前老版本加密的脚本，无法用新版本的程序解密，老版本加密后是二进制数据，新版本加密后是16进制数据。楼主的应该就是老版本。

一个hello world程序使用新版本加解密测试

摘录一段blib/lib/Filter/Crypto.pm中的警告，请看高亮部分，如果加密后的代码可以在你机器上运行，你又有一定的调试技巧，就一定可以解密出源代码。

WARNING

Perl source code decryption filters work by intercepting the source stream (read
from the encrypted file) and modifying it (in this case, decrypting it) before
it reaches the Perl parser. Clearly, by the time the source reaches the parser
it must be decrypted, otherwise the script cannot be run. This means that at
some stage every part of the script must be held in memory in an unencrypted
state, so anyone with the appropriate debugging skills will be able to get it.

If perl was built with DEBUGGING then running the script with the perl's B<-Dp>
command-line option makes this much easier. Even without a DEBUGGING perl, the
script can still be run under the Perl debugger (perl's B<-d> command-line
option), whose C<l> command will list the (decrypted) source code that was fed
to the parser.

In fact, with the introduction of the Perl compiler backend modules it is now
easy to get at the decrypted source code without any debugging skills at all.
To quote L<B::Deparse>:

B::Deparse is a backend module for the Perl compiler that generates perl
source code, based on the internal compiled structure that perl itself
creates after parsing a program. The output of B::Deparse won't be exactly
the same as the original source, since perl doesn't keep track of comments
or whitespace, and there isn't a one-to-one correspondence between perl's
syntactical constructions and their compiled form, but it will often be
close.

To make debugging and deparsing more difficult, the source code decryption
filter implemented in this distribution contains checks to try to disallow the
following:

Mx￠Xgt 有些系统或者有些APK不会这样生成,有啥规律吗

这是系统行为，找到PackageManagerService.java文件：

随机生成16个字节，然后base64编码一下，防止应用重名。

petersonhz 你自己编译过lineage么？

petersonhz 红米2支持LineAge么[em_6]

好像不支持红米2,小米手机支持这些型号

去这个网站看看那吧

把32位十进制有符号整数，转换为十六进制

“俄罗斯是世界上最不公平的国家之一，87%的财富集中在最富有的10%人手中”，这段话来自《21 Lessons for the 21st Century》。楼主可以把普金说这段话的视频、新闻找出来，我怀疑是fake news。

完全不懂，不过从scholar.google.com帮楼主下载到两篇论文。
