Don't other file sending services also encrypt files?

While many services claim to encrypt your files, the reality is that most only provide encryption-in-transit or, in some cases, encryption-at-rest.

Encryption-in-transit means that your files are encrypted while they are being sent to the service's servers. However, once the files arrive, the service has the ability to decrypt and access them because they hold the encryption keys. This creates a significant privacy risk, as the service can potentially view, analyze, or share your data.

Encryption-at-rest means that the service encrypts your files while they are stored on their servers. Again, since the service manages the encryption keys, they can decrypt and access your files at any time.

In contrast, aero.zip employs end-to-end encryption (in addition to encryption-in-transit and encryption-at-rest), where files are encrypted in your browser before they are uploaded, and the secret key never leaves your device. This ensures that only you and the person you share the link with can access the files, providing a much higher level of privacy and security.
