-GoCryptFS Security
-==================
-
-Master Key Storage
-------------------
-
-The master key is used to perform content and file name encryption.
-It is stored in `gocryptfs.conf`, encrypted with AES-256-GCM using the
-Key Encryption Key (KEK).
-
-The KEK is generated from the user password using `scrypt`.
-
-![](https://rawgit.com/rfjakob/gocryptfs/master/Documentation/master-key.svg)
-
-File Contents
--------------
-
-All file contents are encrypted using AES-256-GCM (Galois/Counter Mode).
-
-Files are segmented into 4KB blocks. Each block gets a fresh random
-128 bit IV each time it is modified. A 128-bit authentication tag (GHASH)
-protects each block from modifications.
-
-Each file has a header containing a random 128-bit file ID. The
-file ID and the block number are mixed into the GHASH as
-*additional authenticated data*. The prevents blocks from being copied
-between or within files.
-
-![](https://rawgit.com/rfjakob/gocryptfs/master/Documentation/file-content-encryption.svg)
-
-To support sparse files, all-zero blocks are accepted and passed through
-unchanged.
-
-File Names
-----------
-
-Every directory gets a 128-bit directory IV that is stored in each
-directory as `gocryptfs.diriv`.
-
-File names are encrypted using AES-256-EME (ECB-Mix-ECB wide-block encryption,
-see https://github.com/rfjakob/eme for details) with the directory IV
-as initialization vector. EME fixes the prefix leak that occours with CBC
-encryption.
-
-![](https://rawgit.com/rfjakob/gocryptfs/master/Documentation/file-name-encryption.svg)
-
-The Base64 encoding limits the usable filename length to 176 characters.
