Storing and sharing files on the cloud is increasingly popular. However, it is logical to be concerned about the security of the data kept there because, although using encryption is supported, the service providers may still have access to the contents of your files. BoxCryptor can help you solve this problem by offering an extra security layer.
Using BoxCryptor is not too difficult. In this respect, there is a convenient wizard to help you create an account if you do not have one. An important step is setting a password and/or a PIN to prevent unauthorized access. Likewise, you should also add the desired folders. Fortunately, there is even an online manual to answer any possible question.
BoxCryptor works by encrypting your files before they are uploaded to the Cloud. In this regard, it integrates seamlessly with more than 30 cloud storage providers. Yet, it is shame that it does not support such popular services as Sync.com and pCloud, which does not mean that you cannot use them manually. BoxCryptor supports collaborative work. In this respect, it is good that it lets you set custom policies, manage users and audit work.
One of the main advantages of using BoxCryptor is its end-to-end encryption, which uses a unique random file key generated at the moment the file is created. Moreover, since your master password is stored locally, the providers of this service do not have access to it. The related inconvenience is that there is no means to recover a forgotten password or your encrypted data along with it. In spite of everything said, it is also true that you will have to trust the service providers as the code of the app is closed source.
To conclude, BoxCryptor seems to be effective in protecting your data by minimizing the risks of their being accessed by third parties. Fortunately, it is free for non-commercial use. Yet, there are restrictions as to the number of Cloud storage services you can integrate to. The paid plans offer some additional benefits, particularly related to team work. However, you should know there is no refund policy.
