Kone Base64 Auto Decoder

kone.gg 게시글의 Base64 인코딩 링크를 자동으로 디코딩합니다. (ON/OFF 지원) Kone Base64 Auto Decoder는 kone.gg 서브(kone.gg/s/*) 게시글에서 Base64로 인코딩된 문자열을 자동으로 감지하고, 원본 URL로 변환하여 클릭 가능한 링크로 표시해 주는 확장프로그램입니다. 주요 기능: • 자동 감지 및 디코딩 – 페이지 로딩 시 게시글 본문과 댓글 영역의 Base64 문자열을 자동으로 찾아 디코딩합니다. • 이중 인코딩 지원 – Base64가 두 번 인코딩된 문자열도 자동으로 2단계에 걸쳐 디코딩합니다. • 2패스 스캔 – 디코딩 과정을 2회 반복 실행하여, 단일 인코딩과 이중 인코딩 문자열을 모두 빠짐없이 처리합니다. • Shadow DOM 지원 – 게시글 본문이 Shadow DOM 내부에 렌더링되는 구조에서도 정상적으로 작동합니다. • 접힌 영역 처리 – 태그로 접혀 있는 콘텐츠도 감지하며, 사용자가 펼칠 때 자동으로 디코딩합니다. • ON/OFF 토글 – 팝업에서 한 번의 클릭으로 기능을 활성화하거나 비활성화할 수 있습니다. 비활성화 시 디코딩된 요소가 원본으로 복구됩니다. • 다시 스캔 – 팝업의 "다시 스캔" 버튼을 통해 현재 페이지를 수동으로 재스캔할 수 있습니다. • 원본 보기 – 디코딩된 각 항목 옆의 "원본" 버튼을 클릭하면 인코딩된 원래 문자열을 확인할 수 있습니다. 이 확장프로그램은 kone.gg/s/* 경로에서만 작동하며, 다른 웹사이트에서는 실행되지 않습니다. • 글 작성시 작동되는것을 막았습니다

RdTools

JSON Editor, Base64 Tool, Timestamp Converter, and Authorization Generator ## Summary (One-liner) A powerful developer toolbox featuring a high-precision JSON editor with BigInt support, Timestamp converter, Base64 tools, and Auth generator—optimized for the Chrome Side Panel. **RdTools** is the ultimate productivity companion for modern web developers. Stop switching between multiple browser tabs or external sites to format JSON, convert timestamps, or encode strings. RdTools brings essential debugging utilities directly into your browser’s **Side Panel**, providing a seamless, high-performance workflow. ### 🚀 Key Purpose RdTools is designed to solve the common "precision loss" and "context switching" problems developers face during API debugging and data manipulation. From handling massive IDs (BigInt) to exploring deeply nested JSON strings, RdTools ensures your data remains accurate and accessible. #### 1. Advanced JSON Editor (High Precision) * **BigInt Data Safety**: No more truncated IDs! RdTools preserves the precision of long integers (16+ digits) like Snowflake IDs, which standard JS tools often break. * **Intelligent Search**: Find keys or values instantly with character-level highlighting. The tool automatically expands parent nodes to reveal hidden matches. * **Auto-Nested Parsing**: Detected a JSON-serialized string inside a value? RdTools parses it recursively so you can explore it as a sub-tree. * **Dual-Mode Editing**: Edit simple values inline or use the formatted Modal editor for long strings and nested objects. * **Validation**: Real-time syntax highlighting and error messaging for invalid JSON inputs. #### 2. Unix Timestamp Converter * Seamlessly convert between Unix timestamps (seconds & milliseconds) and local human-readable date strings. * One-click "Current Time" retrieval for quick reference. #### 3. Base64 & Encoding Tools * High-speed Base64 encoding and decoding. * Full **Unicode/UTF-8 support**, ensuring your special characters and emojis are never garbled. #### 4. Authorization Header Generator * Instantly generate standard `Basic Auth` headers for your API calls. ### 💻 Seamless Integration * **Side Panel First**: Optimized specifically for the Chrome Side Panel, allowing you to debug alongside your active tab without losing focus. * **Vertical Layout**: Designed with a stack-based layout to maximize vertical space, perfect for side-by-side work. * **Developer-Centric UX**: 1-second "Copy Result" toast, "Prettify" shortcuts, and a dark, high-contrast UI that matches your code editor. ### 🔒 Privacy & Security RdTools runs entirely locally in your browser. Your data—JSON payloads, credentials, and converted strings—never leaves your computer. No tracking, no external API calls, just pure local performance. **Elevate your development workflow today with RdTools!**
