Pros & Cons:
Our Review:
Cryptomator is a new entry in this category of encryption for cloud storage. It is well matched to the needs of many of the readers of this article and most home users. One key design objective is security through simplicity. Cryptomator provides transparent (on-the-fly), client-side encryption for cloud storage. Cryptomator is free and open-source software, which assures that backdoors are unlikely.
Cryptomator is platform independent, and especially suitable for less technically experienced users. The user interface is very simple, and it is fairly easy to intuitively discover all the functions and options of Cryptomator. A FAQ and a rough version of a user manual already exist. They provide good help in getting started. The architecture is "Type 2" as discussed in Encryption Methods.
Cryptomator is based on simple, clean, and straightforward architecture, which uses time-proven, standard encryption functions. It is open-source, which makes independent cryptographic review possible. Those factors and the evident attention to detail and documentation by the developers lend a great deal to my confidence in the security of Cryptomator.
The developers consulted with university mathematicians and other encryption experts and received extensive feedback from the encryption community in their quest to avoid and eliminate vulnerabilities. They recently received a CeBIT Innovation Award (from the German Federal Ministry of Education and Research and a sponsoring Partner) for their design.
