In the digital age, file sharing has become a vital part of both personal and professional communication. Filifly, a cloud-based file-sharing platform, has just been relaunched with enhanced features, one of the most important being its End-to-End Encryption (E2EE).
This advanced security measure ensures that users can send and receive files with complete privacy, something that’s becoming increasingly crucial as cyber threats continue to evolve.
What is End-to-End Encryption?
End-to-end encryption is a system of communication where only the sender and the receiver can access the content of a message or file. This means that even the service provider—Filifly in this case—cannot decrypt or access the files being shared. As a result, your data remains private and secure, preventing any potential interception from malicious actors during the transfer.
How Does Filifly’s End-to-End Encryption Work?
Filifly’s End-to-End Encryption operates in the background, ensuring that files are encrypted before leaving your device and can only be decrypted by the recipient. Here’s how it works in simple steps:
- Encryption on Upload: When you upload a file to Filifly, the platform uses strong encryption algorithms to scramble the data before it even reaches the server. This means that your file is protected the moment you start the upload process.
- Code Generation: A 10-digit file key is generated on the client side, and this key is never shared or stored as plaintext on our server. Instead, we create a hash of the 10-digit key on the client side, which is then uploaded to our server. This hashed key is used to identify and process your file retrieval request when you wish to download it later. The code is only displayed after your file(s) have been successfully uploaded. Be sure to copy or remember it, as it is required to access your file. Without the code, no one will be able to read or retrieve the file.
- Secure Transmission: After the file is encrypted, it is sent to Filifly’s server for storage. However, since the file is already encrypted, it is unreadable to anyone who might intercept it during the transmission process.
- Decryption on Download: When the recipient downloads the file, it is still in its encrypted state. Only their device, using a specific decryption key (10-digit file key), can decrypt the file and make it readable.
- No Third-Party Access: Even though the files are stored on Filifly’s servers, they are only accessible to the sender and the recipient. The platform has no access to the encryption keys, ensuring that no third parties—whether hackers, government agencies, or even Filifly itself—can decrypt the file.
- Social-Media Integration: When you share a file link via social media, the privacy of the file URL is governed by the privacy settings of the social media platform you use. Filifly is not responsible for whether those social media platforms offer an end-to-end encryption or not.
Why End-to-End Encryption is Essential
The importance of End-to-End Encryption cannot be overstated, particularly when dealing with sensitive information. Here are a few reasons why it’s crucial:
- Prevents Unauthorized Access: With encryption, even if someone gains access to the server or intercepts the file during transfer, the data will be unreadable without the decryption key.
- Protects Privacy: Filifly’s encryption ensures that your private files, personal information, or business documents stay secure from prying eyes, preserving your confidentiality.
- Enhanced Security for Remote Work: As more people work remotely and rely on file-sharing platforms, having secure file transmission is vital to prevent data breaches or leaks of sensitive corporate information.
How Filifly Goes Beyond with Additional Security Features (with an account*)
In addition to End-to-End Encryption, Filifly offers several other features to further enhance the security of file transfers when you have an active account at Filifly:
- Password Protection: Users can set passwords for their shared files, ensuring that only those with the correct password can access the data.
- File Expiry: Filifly offers the option to set an expiration date for files, meaning they are automatically deleted after a certain period, reducing the risk of prolonged exposure.
- Secure Links: Filifly provides the ability to generate secure sharing links that are unique and can be restricted to specific recipients.

Conclusion
With its newly relaunched platform, Filifly stands out as a secure, easy-to-use solution for file sharing, especially with the implementation of End-to-End Encryption. Whether you’re sharing personal documents or sensitive business files, Filifly ensures that your data remains protected at every step. By keeping your information private and out of the hands of unauthorized individuals, Filifly offers peace of mind for all your file-sharing needs.
