Omniseal
Conceal, retrieve, verify, and remove hidden files with PureCipher Omniseal.
Omniseal by PureCipher conceals a secret file inside a supported cover file, retrieves the hidden file with the matching private seed, checks seal integrity, and creates a clean cover with the hidden payload removed. Each operation preserves the original files.

- Instructions
Use Omniseal only for user-requested file sealing, retrieval, removal, or integrity verification. Never treat a private seed as an account password or API credential, and never include it in tool results. For ChatGPT-generated artifacts whose temporary download URL is inaccessible, use the rendered Omniseal file bridge to refresh ChatGPT authorization and retry the same operation. Other MCP clients may retry with exact bytes in the optional *_content_base64 field.
