* Remove --extpass parameter, because that encourages tool writers to do bad things like storing a password in a file and using --extpass="cat filename".
The password can now be passed in to stdin without problems, so tools should use that.
* Works with zuluMount GUI, https://mhogomchungu.github.io/zuluCrypt/
* Fix a bug that prevented deleting symlinks, see https://github.com/cryfs/cryfs/issues/2
* Gracefully accept modifications to the file access times instead of failing, although they're not stored yet (they will be stored in 0.9.0). This should fix https://github.com/cryfs/cryfs/issues/4
* Config File Encryption: Configuration files are encrypted with two ciphers. The user specifies a password, which is then used with the scrypt KDF to generate the two encryption keys.
- Inner level: Encrypts the config data using the user specified cipher.
- Outer level: Encrypts the name of the inner cipher and the inner level ciphertext using aes-256-gcm.
The config file is padded to hide the size of the configuration data (including the name of the cipher used).
* No external config file needed: If the configuration file is not specified as command line parameter, it will be put into the base directory. This way, the filesystem can be mounted with the password only, without specifying a config file on command line.
* Better error messages when base directory is not existing, not readable or not writeable.
* Allow --cipher=xxx to specify cipher on command line. If cryfs is creating a new filesystem, it will use this cipher. If it is opening an existing filesystem, it will check whether this is the cipher used by it.
