Free secure cloud wuala3/2/2023 One place Tresorit shines (and has a lot of potential) is in sharing encrypted files. Tresorit only supports Windows at the moment, and offers no mobile apps, but their Windows utility is very user friendly and a bit easier to get your arms around than some of the other tools that are bit more complicated to use (but offer more features). This means that no one can decrypt those files without your password - including Tresorit employees. Like other encrypted cloud storage services, all encryption takes place locally on your computer. You can read more about their approach to security here and here. Wuala uses AES-256 for encryption, RSA 2048 for signatures and for key exchange when sharing folders, and SHA-256 for integrity checks. The decryption process still takes place locally, but Wuala does - temporarily - have your password. When you sync and access your files on mobile devices, your password is required in order to encrypt and decrypt your files, and Wuala uses it to make sure you are who you say you are. If you put files in your public folder, they’re definitely unencrypted. SpiderOak’s, but they’re similar - when you share a file with someone, the file is unencrypted so they can access it without your password. In order to give you access to your files on the go (and in order to share files with others) Wuala does have to make some compromises in the security department. Wuala offers file versioning, cross-computer syncing, and mobile apps to help you keep working when you’re on multiple computers or away from your desk. You don’t sacrifice features to get this level of security though. Your password is never transmitted anywhere, and again, this means that if you forget it and don’t have unencrypted versions of your files locally, you’re out of luck. Like SpiderOak, Wuala handles encryption and decryption locally using a password you set, so no one can access your files.įurthermore, Wuala uploads different segments of your files to different servers, so they can’t even identify what data belongs to which users. You start with 5GB for free, and after that it’s $US4 per month for 20GB, $US7 per month for 50GB, or $US12 per month for 100GB. Wuala encrypts your files locally and then uploads them to the cloud for safe keeping. If you’re looking for a secure option that stores your files in an encrypted form but doesn’t sacrifice usability, SpiderOak is definitely worth a look. When your remote session is over, they destroy your password, so you can be comfortable that you’re the only person who can access your files. The encryption and decryption process still takes place locally, but the only thing that’s stored on SpiderOak’s servers are your password, so they can authenticate you and direct you to the right files. In the past, SpiderOak limited its remote access and syncing options, but SpiderOak Hive, their new syncing service, along with their iOS and Android apps let you take your encrypted files on the go. At the same time, this also means that if you lose your password, SpiderOak can’t retrieve it - or decrypt your locked files - for you. Also, since your data is encrypted locally with a password you choose, they have absolutely no way of decrypting it to see what’s in your data store. The only unencrypted versions live on your local computer. Essentially, your data is completely private because you’re the only person who knows what’s being encrypted and transmitted. SpiderOak’s “Zero Knowledge” privacy policy notes that because the encryption process takes place locally, they have no way of knowing what you’re storing with them. All of your files are encrypted locally on your computer and then uploaded to SpiderOak’s servers.Any changes you make to your files and folders are synced with the local decrypted versions before being secured and uploaded. SpiderOak starts you off with 2GB for free, with more storage available at $US10 per month for each additional 100GB you need.
