我正在开发一项功能，允许用户上传文件（.csv、.xls 或 .xlsx）。该文件有一列包含电子邮件，然后我使用 SHA-256 将该电子邮件散列到另一列，最后导出文件。这是示例 .csv 文件：
abc@gmail.com
xyz@gmail.com
"abc@gmail.com","48ddb93f0b30c475423fe177832912c5bcdce3cc72872f8051627967ef278e08"
"xyz@gmail.com","32e19a491662fd86de7d3806b1199b76f0ee44e928d3475f05b0c8a59912c097"
这是我的代码，我使用 phpoffice/phpspreadsheet 来读/写：
