Today I will tell you about some cloud services that support encryption, namely, encryption of the client part. This is very important for confidentiality and overall data security. Encryption of the client part is not provided by such services as Google Drive, DropBox, OneDrive, Yandex disk and others. But it is provided by the following:
Mega – (MEGA Encrypted Global Access) is the ambitious cloud file sharer Kim Dotcom, founder of the legendary Megaupload.
Mega encrypts all content directly in the browser using AES; users can transfer files to each other in encrypted form, with all data stored in the cloud; file access keys are not shared publicly, but are distributed via Friend-to-Friend, between trusted users.
Free disk space: 50 GB (!)
pCloud – safe cloud to store your files. There are two approaches to security: first, all information is transmitted to pCloud servers via the TLS/SSL protocol and copied to at least 3 servers with different locations in a highly secure data center; second, you can subscribe to pCloud Crypto ($3.99 per month) and take advantage of client side encryption with a simplified interface for use.
Free disk space: 20 GB
iDrive is an ideal tool for online backups with high privacy. If you want to save a copy of important documents to a cloud server, iDrive is what you’re looking for. It’s easy to use: download the iDrive software, run the app, and select folders to sync.
You can back up your PC, Mac, iPhone, iPad and Android devices in one account. Pretty high level of data security. Transfer and storage of files with 256-bit AES encryption using a user-defined key, which is not stored anywhere on servers.
Free disk space: 5 GB
SpiderOak – is considered one of the safest cloud data stores. (even promoted by Snowden).
The developers assure that the password to access the account is not transferred anywhere, and the first login creates a special key that allows the desktop client access to the cloud storage.
Free disk space: 10 GB
The last service is the most popular and limited in functions (very!) on the free tariff. Be careful in choosing a cloud service.
