End-to-end encryption

Tresorit's automatic, built-in end-to-end encryption safeguards confidential documents from unauthorized access and guarantees that only you have access to them.

  • Public key cryptography

    Tresorit encrypts every file on your devices before they are uploaded to the cloud applying the Advanced Encryption Standard algorithm using 256-bit keys. Your files never get decrypted on Tresorit's servers.

  • Zero-knowledge

    Zero-knowledge privacy means that no one, not even Tresorit, can look into the content of your files. Only you and those who you decide to share with can access them.

  • Client-side integrity protection

    Applying a Message Authentication Code to each file, Tresorit guarantees that the contents of your files cannot be modified without your knowledge, even if somebody hacks our system.
