Cryptomator is an open source file encryption software that provides users with a secure and backdoor-free encryption solution. Cryptomator’s technology complies with the latest standards and uses AES and a 256-bit key length to encrypt files and filenames. With Cryptomator, users can easily encrypt and decrypt personal files. When the user locks the file directory, Cryptomator can automatically exit to ensure that no traces are left, further enhancing data security. In addition, Cryptomator also supports integration with mainstream cloud storage services such as Dropbox and Google Drive, allowing users to enjoy the convenience of cloud storage without sacrificing file security.。

privacy

256 bit key (unlimited strength policy bundled with native binaries）
Scrypt key derivation
Cryptographically secure random numbers for salts, IVs and master keys
Wipe sensitive data from the heap as quickly as possible

consistency

Authenticated encryption is used on file contents to identify changed ciphertext before decryption
I/O operations are transactional and atomic (if the file system supports）
Each file contains all the information needed for decryption (except the key of course), no common metadata means no SPOF
