Crt_Subdomain_Fetcher

这是一个通过使用crt.sh获取给定域名的子域名的Python脚本。

依赖项

在运行此脚本之前，请确保您的系统上安装了以下软件包：

• Python 3.x
• requests

您可以使用pip安装所需的Python库：

pip install requests

使用方法

python Crt_Subdomain_Fetcher.py [-t DOMAIN] [-f FILE] [-threads NUMBER]

参数说明

• -t DOMAIN: 指定单个目标域名。
• -f FILE: 包含域名列表的文件，每行一个域名。
• -threads NUMBER: 选择使用的线程数（默认为5）。

示例

1. 查询单个域名的子域名：

   python Crt_Subdomain_Fetcher.py -t example.com

2. 从文件中读取域名进行查询：

   python Crt_Subdomain_Fetcher.py -f domain_list.txt

3. 使用自定义线程数进行查询：

   python Crt_Subdomain_Fetcher.py -f domain_list.txt -threads 20

输出

脚本会生成一个包含所有子域名的文件，默认为out.txt，包含通配符的结果存到wildcard_subdomains.txt，不包含通配符的结果存到non_wildcard_subdomains.txt。这些文件将保存在脚本执行目录中。

注意事项

• 确保您输入的文件路径正确，否则程序会抛出“File not found”错误。
• 在调用API时请遵循相关法律法规，确保对方服务器的稳定性和您的合法使用。

Crt_Subdomain_Fetcher

This is a Python script to fetch subdomains for given domains using crt.sh.

Dependencies

Before running this script, ensure the following packages are installed on your system:

• Python 3.x
• requests

You can install the required Python library using pip:

pip install requests

Usage

python Crt_Subdomain_Fetcher.py [-t DOMAIN] [-f FILE] [-threads NUMBER]

Argument Description

• -t DOMAIN: Specify a single target domain.
• -f FILE: Specify a file containing a list of domains, one per line.
• -threads NUMBER: Choose the number of threads to use (default is 5).

Examples

1. Fetch subdomains for a single domain:

   python Crt_Subdomain_Fetcher.py -t example.com

2. Fetch subdomains from a list of domains in a file:

   python Crt_Subdomain_Fetcher.py -f domain_list.txt

3. Use a custom number of threads:

   python Crt_Subdomain_Fetcher.py -f domain_list.txt -threads 20

Output

​ The script will generate a file containing all subdomains, defaulting to out.txt. Results with wildcards will be saved to wildcard_subdomains.txt, and results without wildcards will be saved to non_wildcard_subdomains.txt. These files will be stored in the directory where the script is executed.

Notes

• Ensure the file path you provide is correct, or the program will throw a "File not found" error.
• When using the API, comply with legal regulations and ensure the stability of the server and your lawful use.
