🔐 Crypto | 密客

如果你使用或参考了本项目，不妨Star⭐一下~

This app offers a variety of encryption features, including both basic and advanced encryption methods. Users can choose from key-supported ciphers like Caesar, Keyword, RC4, DES, etc., with a simple operation process that only requires entering data in a three-text-box mode of plaintext-key-ciphertext. In addition to basic encryption, it includes complex encryption methods like one-dimensional CA, RSA, and DH key exchange, as well as file encryption functionality, supporting direct writing of file contents into text boxes for encryption and decryption. Moreover, it provides dual-machine encryption functionality, implementing inter-machine ciphertext and key communication based on Windows' Socket. Its GUI design features a dark-tone purple as the base color, offering a harmonious and unified interface style that focuses on user interaction experience, making the overall usage more user-friendly. This app is a comprehensive encryption tool suitable for users who need secure data processing.

这款应用提供了多样化的加密功能，包括基础和复杂的加密方法。用户可以选择Caesar、Keyword、RC4、DES等密钥支持型密码，操作简单，只需在明文-密钥-密文三文本框模式中输入相应数据。除了基础加密，还包括一维CA、RSA和DH密钥交换等复杂加密方式，以及文件加密功能，支持将文件内容直接写入文本框进行加解密。另外，提供了双机加密功能，基于Windows的Socket实现多机间的密文和密钥通信。其GUI设计采用暗色调紫色为基色，界面风格和谐统一，注重用户交互体验，使得整体使用感更加友好。这款APP是一个综合性的加密工具，适合需要安全数据处理的用户。
