ffsend is a command-line tool for securely sharing files over the internet using HTTP. It provides end-to-end encryption, ensuring that only the intended recipient can decrypt and access the file. ffsend uploads the file to a temporary server (by default, a public instance, but you can also host your own) and provides a unique URL containing the decryption key. The recipient then uses this URL to download and decrypt the file.

Its main strengths are simplicity, security, and ease of use. It's commonly used for quickly sharing sensitive information without relying on email or other less secure methods. It supports features like setting download limits, expiration times, and custom passwords. It is written in Rust, offering inherent memory safety, and prioritizes privacy through cryptographic measures.

The default public server is a shared resource and may be subject to rate limiting or downtime. For critical applications, consider hosting your own ffsend server instance. Ensure the receiving party has the correct URL, as losing it means the file is inaccessible.

To download a file: ffsend

ffsend has a server component available for self-hosting, see the offical github repository for more information.

ffsend was developed as a secure and easy-to-use file-sharing solution, addressing the need for privacy-focused data transfer in various contexts. The implementation in Rust contributes to its security profile. It has gained popularity among users who require a simple, encrypted alternative to traditional file-sharing methods.
