#   For a library or package, you might want to ignore these files since the code is

# pipenv
#   According to pypa/pipenv#598, it is recommended to include Pipfile.lock in version control.
#   However, in case of collaboration, if having platform-specific dependencies or dependencies
#   having no cross-platform support, pipenv may install dependencies that don't work, or not
#   install all needed dependencies.
#Pipfile.lock

# poetry
#   Similar to Pipfile.lock, it is generally recommended to include poetry.lock in version control.
#   This is especially recommended for binary packages to ensure reproducibility, and is more
#   commonly ignored for libraries.

# pdm
#   Similar to Pipfile.lock, it is generally recommended to include pdm.lock in version control.
#pdm.lock
#   pdm stores project-wide configurations in .pdm.toml, but it is recommended to not include it
#   in version control.

# Sign-Sacker (签名掠夺者) - 2.0

## 介绍

Sign-Sacker(签名掠夺者)：一款数字签名复制器，可将其他官方exe中数字签名，图标，详细信息复制到没有签名的exe中，作为免杀，权限维持，伪装的一种小手段。

## 2024-1-4 项目停更

1. 微调了下代码，只允许了exe，dll文件
2. 项目停更，江湖再见

## 更新 2.0

分别导入含有签名和需要签名的文件，点击生成即可，玩免杀的可能会用到。

新增功能：

1. 掠夺高清图标，完美复刻。
2. 掠夺exe详细信息，以假乱真。

### 详细信息对比
唯一的遗憾是语言暂未更改，文件版本号是由于飞书实际和显示有差别，大多数是一致的，因此我未做细微调整。
