What is a C9R file? A C9R file is a file that has been encrypted by Skymatic Cryptomator, an open-source data encryption tool. It contains a file or directory that a user has placed in their Cryptomator vault. C9R files can be decrypted by unlocking the vault in which they are stored.
More Information C9R file shown in Apple Finder Cryptomator is a file encryption app that allows users to store files in a virtual drive and then lock that drive. Locking the drive encrypts the stored files, using AES-256 encryption. Often, users place their Cryptomator drives in cloud storage services , so they can access the drives (and the files they contain) from multiple devices. Files encrypted by Cryptomator use the .c9r extension, to denote they've been encrypted. These files also have encrypted filenames produced using AES-SIV encryption. Thus, a file previously named Example.rtf may have a filename like eHwTYFBFYdmnj2cVBF-hgHXjoH7sVD4ZUwpz.c9r after being encrypted by Cryptomator.
