What types of encryption does Tresorit use to protect my files?

Asked 4 months ago
Tresorit employs a robust security architecture that includes end-to-end encryption to safeguard users' files. The encryption process starts on the user's device, ensuring that files are encrypted before they are uploaded to the Tresorit cloud storage. This means that only the user can access their files, as the encryption keys are never stored on Tresorit's servers. Tresorit utilizes the Advanced Encryption Standard, known as AES-256, which is widely recognized as one of the most secure encryption methods available. This level of encryption is often used by governments and financial institutions for protecting sensitive data. The files are encrypted using a unique key, which is generated for each file and stored securely on the user's device. Additionally, Tresorit implements zero-knowledge encryption, meaning that even Tresorit does not have access to the encryption keys. This ensures that data remains private and is only accessible by the user who uploaded it. The combination of end-to-end encryption and zero-knowledge architecture makes Tresorit an extremely secure option for users who prioritize data privacy and protection.
