SEAL provides a service for transferring files such as documents, media, design assets, datasets, and archives through the use of temporary links. Within the web application, files are encrypted in the user's browser prior to upload, while command-line interface (CLI) encryption occurs locally. Users can configure settings like expiry dates, passwords, single-use access, download limits, or NDA requirements, as well as review a signed access log and revoke hosted access at any time. Recipients can access the shared links through their browsers without needing to create an account. Additionally, SEAL features a Telegram bot, a Mini App, a CLI, an SDK, an HTTP API, and a local standard input/output MCP server. AI agents are capable of either sharing or requesting files and sensitive information; after establishing a connection, files can be sent to a SEAL inbox, with the agent receiving a handle instead of a traditional link. The Telegram bot handles file encryption on its host device, allowing chat attachments to be processed through Telegram's system first, while its Mini App performs encryption directly on the user's device. Each individual seal allows for transfers of up to 1 GB and remains active for seven days, with one-time upgrades available to increase capacity and extend the lifetime of the seal; however, each file must not exceed a limit of 10 GB. In this way, SEAL provides a versatile and secure file-sharing solution tailored to various user needs.
