# AGEX Bundle Metadata Redactor Rewrite exposed AGEX metadata like original filename or signer ID without touching ciphertext bytes > Canonical page: https://elysiatools.com/en/tools/agex-bundle-metadata-redactor - **Category:** Security - **Keywords:** agex, metadata redaction, bundle sanitization, signer id, filename privacy ## Overview This tool is for privacy cleanup before distribution. It lets you keep, clear, or replace visible metadata fields while leaving the encrypted payload unchanged. If the bundle was signed, the signature is removed after metadata changes because signatures cover the metadata too. ## Inputs - **Bundle File** (file) - **Filename Mode** (select) - **Replacement Filename** (text): shared-file.bin - **MIME Type Mode** (select) - **Replacement MIME Type** (text): application/octet-stream - **Signer ID Mode** (select) - **Replacement Signer ID** (text): distribution-key ## When to use - Before distributing an AGEX bundle to external partners to prevent leaking internal file naming conventions. - When you need to strip sensitive signer identity labels or signatures from an encrypted package. - To standardize MIME types or filenames across multiple encrypted bundles for public release. ## How it works - Upload your AGEX bundle file containing the encrypted payload and exposed metadata. - Select whether to keep, clear, or replace the filename, MIME type, and signer ID fields. - Process the file to generate a sanitized AGEX bundle with updated metadata and stripped signatures, leaving the ciphertext bytes untouched. ## Use cases - Removing internal developer signer IDs from production-ready AGEX bundles. - Replacing sensitive original filenames with generic placeholders like 'shared-file.bin' before public distribution. - Clearing MIME type metadata to prevent third parties from identifying the underlying file format. ## Frequently asked questions ### Does this tool decrypt or modify the encrypted payload? No, the tool only modifies the unencrypted metadata fields and leaves the ciphertext bytes completely untouched. ### Why is the signature removed after I edit the metadata? Signatures cover both the metadata and the payload; modifying any metadata field invalidates the original signature, so it is stripped. ### What options do I have for the metadata fields? You can choose to keep the original value, clear it entirely, or replace it with a custom string. ### Which metadata fields can I redact? You can redact or replace the original filename, the MIME type, and the signer ID. ### Does this tool support bulk processing? This tool processes one AGEX bundle file at a time. ## Related tools - [AGEX Bundle Diff](https://elysiatools.com/en/tools/agex-bundle-diff): Compare two AGEX bundles and highlight metadata or protection-setting differences - [AGEX Bundle Inspector](https://elysiatools.com/en/tools/agex-bundle-inspector): Inspect AGEX bundle metadata without decrypting the file contents - [JSON-LD Generator from CSV](https://elysiatools.com/en/tools/json-ld-generator-from-csv): Turn CSV or Excel rows into Schema.org JSON-LD for articles, products, or events, with validation-ready output for SEO workflows - [Batch Podcast Publisher Pack](https://elysiatools.com/en/tools/audio-batch-podcast-publisher-pack): Normalize a batch of podcast episodes, apply metadata and chapters, and package validated delivery files in one ZIP. - [OCR PDF to Structured JSON Bridge](https://elysiatools.com/en/tools/ocr-pdf-to-structured-json-bridge): Extract the PDF text layer with geometry (lines by y-position, tables by column gaps, headings by font size, colon key-value pairs), then fill a user-supplied JSON Schema field by field — labels matched by normalized keys, values coerced to declared types and validated with ajv. - [PDF Page Range Extractor](https://elysiatools.com/en/tools/pdf-page-range-extractor): Extract only selected PDF pages with OpenDataLoader and export the subset as Markdown, JSON, or text - [Structured Log Analyzer](https://elysiatools.com/en/tools/structured-log-analyzer): Detect common log formats, extract core fields, infer field types, and export parsed logs as JSON, CSV, or SQL inserts - [Media Metadata to JSON](https://elysiatools.com/en/tools/media-metadata-to-json): Extract audio/video metadata as JSON with ffprobe. ## Samples - [Distributed Tracing Samples](https://elysiatools.com/en/samples/distributed-tracing-samples): Comprehensive distributed tracing examples using Jaeger, OpenTelemetry, and other modern observability tools for microservices architecture - [JWT Samples](https://elysiatools.com/en/samples/jwt-samples): Comprehensive JWT examples from basic token structure to advanced security implementations - [PDF Samples](https://elysiatools.com/en/samples/pdf-samples): Generated PDF samples from tools dated 2026-02-01 to 2026-02-10 - [WebRTC Real-Time Communication Samples](https://elysiatools.com/en/samples/webrtc-samples): Comprehensive WebRTC samples for peer-to-peer audio/video communication, data channels, screen sharing, and signaling server implementation ## Related content - [AGEX Secure File Packaging and Handoff](https://elysiatools.com/en/hubs/agex-secure-file-sharing): Package a file as AGEX, inspect visible metadata, choose passphrase and signature settings, and verify the handoff before delivery.
