Dify Plugins File Encrypt Decrypt

Abstract

1. Introduction

A powerful Dify plugin providing comprehensive local file encryption and decryption capabilities. All file operations are executed entirely on your local machine without any external services, API keys, or internet connections, ensuring maximum data security and privacy. Supports encryption and decryption of various file formats with customizable encryption suffixes.

Supported file types include: .pdf, .txt, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .rtf, .odt, .ods, .odp, .md, .csv, .html, .htm, .css, .js, .json, .xml, .py, .java, .c, .cpp, .h, .hpp, .cs, .php, .rb, .go, .rs, .swift, .kt, .ts, .tsx, .jsx, .vue, .sql, .jpg, .jpeg, .png, .gif, .bmp, .svg, .tiff, .ico, .webp, .mp3, .wav, .ogg, .mp4, .avi, .mov, .wmv, .flv, .mkv, .webm, .zip, .7z, .tar, .gz, .bz2, .xz, .rar, .iso, .dmg, .exe, .msi, .apk, .ipa, .deb, .rpm, .sh, .bat, .ps1, .dll, .so, .dylib, .lib, .a, .o, .class, .jar, .war, .ear, .swf, .fla, .as, .mxp, .air, .zxp, .pem, .crt, .cer, .der, .p12, .pfx, .key, .pub, .asc, .sig, .gpg, .p7s, .p7b, .p7r, .p7c, .spc, .sst, .stl, .pko, .cat, .crl, .rl, .wrl, .vrm, .vrml, .igs, .iges, .msh, .mesh, .silo, .obj, .mtl, .stl, .dxf, .dwg, .dwf, .gbr, .gtl, .gbl, .gbo, .gbs, .gml, .gko, .gm1, .gm2, .gm3, .cmp, .sol, .stc, .sts, .plc, .top, .drd, .art, .rep, and many more....

2. Objective

Local File Encryption & Decryption‌:Supported file types include videos, images, audio files, documents, code files, executable files, compressed archives, and more.

This project demonstrates how Python can be applied to a real-world Cybersecurity & Ethical Hacking problem.
