The only known ways to recover an encrypted file are via dictionary or brute force attacks. Older versions of the file format used a proprietary algorithm newer versions use the AES encryption algorithm, a block cipher adopted as an encryption standard by the U.S. Most currently used compression formats (with the exception of the older ZIP) allow solid structuring. RAR archives can be of a solid format, in which all of the compressed files are treated as a single data block.RAR does not support tapes, as it uses seek and rename operations on its files. partXXX RAR file, without the need to manually copy and then rejoin the pieces, or for extracting a file from a single piece without needing all pieces. Built-in support for multi-volume files enables the unpacking program to simply prompt the user for the next. RAR is able to efficiently handle split volumes.On its own, Tar does not have this ability. Even if parts of an archive are damaged, it is possible to fully recover the stored data if a large enough recovery record exists.
