 /* File hash
  * In order to make file deduplication work, files can be hashed through different methods.
  * By default, files are hashed through md5 but other methods are available.
- * Possible values are 'md5' and 'md5_outside'.
+ *
+ * Possible values are 'md5', 'md5_outside' and 'random'.
+ * 
  * With 'md5' option, the whole file is hashed through md5. This is the default.
- * With 'md5_outside', md5 is used to hash the first part of the file, the last part of the file
- * and the file's size. This method is fast for large files but cannot be perfect.
+ * With 'md5_outside', hash is computed using:
+ *  - md5 of the first part of the file,
+ *  - md5 of the last part of the file and
+ *  - file's size.
+ * This method offer file deduplication at minimal cost but can be dangerous as files with the same partial hash can be mistaken.
+ * With 'random' option, file hash is set to a random value and file deduplication cannot work anymore but it is fast and safe.
