# AGEX Bundle Inspector Inspect AGEX bundle metadata without decrypting the file contents > Canonical page: https://elysiatools.com/en/tools/agex-bundle-inspector - **Category:** Security - **Keywords:** agex, bundle inspector, metadata, signature, argon2id, xchacha20-poly1305 ## Overview Use this tool when you want to understand what an AGEX bundle contains before decrypting it. It exposes only metadata such as version, file name, size, MIME type, Argon2id settings, and whether a signature block is present. ## Inputs - **Bundle File** (file) ## When to use - Before decrypting an AGEX bundle to verify its origin and integrity via the signature block. - When you need to check the Argon2id key derivation settings used to secure the bundle. - To identify the original file name, size, and MIME type of an encrypted package without entering a passphrase. ## How it works - Upload your AGEX bundle file using the file input field. - The tool parses the unencrypted header and metadata sections of the bundle structure. - It extracts key parameters including the bundle format version, signature status, and Argon2id configuration. - The extracted metadata is displayed instantly in a clean JSON format without accessing or decrypting the payload. ## Use cases - Verifying the signature status of an AGEX bundle before initiating a decryption workflow. - Auditing the Argon2id work factors (memory, iterations, parallelism) used for key derivation. - Identifying the original file extension and MIME type of an encrypted archive. ## Frequently asked questions ### Does this tool decrypt my file contents? No, it only reads the unencrypted metadata header and does not require or accept a decryption passphrase. ### What metadata fields can I inspect? You can view the bundle format version, original file name, file size, MIME type, Argon2id parameters, and signature presence. ### Is my bundle uploaded to a remote server? No, the inspection is performed locally in your browser to ensure your metadata remains private. ### What is the maximum file size supported? The tool supports AGEX bundle files up to 100 MB in size. ### Can I verify if the bundle has been digitally signed? Yes, the inspector checks for the presence of a signature block in the bundle metadata. ## Related tools - [AGEX Bundle Metadata Redactor](https://elysiatools.com/en/tools/agex-bundle-metadata-redactor): Rewrite exposed AGEX metadata like original filename or signer ID without touching ciphertext bytes - [AGEX Bundle Diff](https://elysiatools.com/en/tools/agex-bundle-diff): Compare two AGEX bundles and highlight metadata or protection-setting differences - [Age-like Encrypted File Bundle](https://elysiatools.com/en/tools/age-like-encrypted-file-bundle): Encrypt or decrypt portable password-based file bundles with Argon2id, XChaCha20-Poly1305, and optional signatures - [AGEX Signature Verifier](https://elysiatools.com/en/tools/agex-signature-verifier): Verify the Ed25519 signature attached to an AGEX bundle - [AGEX Secure Share Note](https://elysiatools.com/en/tools/agex-secure-share-note): Generate a plain-language share note for an AGEX bundle so recipients know how to decrypt and verify it safely - [3D Model Viewer & Inspector](https://elysiatools.com/en/tools/3d-model-viewer): Upload an STL, OBJ, GLB or glTF model: exact vertex/triangle counts, bounding-box dimensions, materials, animations and node tree, plus an interactive Three.js viewer (rotate, zoom, shaded/wireframe/normals). - [AGEX Bundle Rewrapper](https://elysiatools.com/en/tools/agex-bundle-rewrapper): Re-encrypt an AGEX bundle with a new passphrase and fresh Argon2id/XChaCha parameters - [Excel to JSON Converter](https://elysiatools.com/en/tools/excel-to-json): Convert Excel file to JSON format, extracting data from the first worksheet ## 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 - [AWS EventBridge Samples](https://elysiatools.com/en/samples/eventbridge-samples): AWS EventBridge examples including event buses, rules, targets, schema registry, custom events, and cross-account event routing for serverless event-driven 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 ## Related content - [AGEX Secure Package Review Before Handoff](https://elysiatools.com/en/hubs/agex-secure-package-review): Generate a test signing key, inspect AGEX bundle metadata, verify its signature with a trusted public key, and stop the handoff when evidence is incomplete. - [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.
