Introduction to rar
Rar is a patented file format, which is used for data compression, archiving and packaging. Its full name is RoshalARchive. The first public version of RAR 1.3 was published in 1993.
Rar usually has a higher compression ratio than ZIP, but the compression/decompression speed is slower.
Volume compression: divided into multiple files after compression.
Solid compression: treat the compressed files as the same file to improve the compression ratio, at the cost of extracting any file in the package and then decompressing the whole compressed package.
Recover records: add redundant data for repair. When the compressed package itself is damaged but there are enough recovery records, the damaged compressed package can be recovered.
Encryption: RAR2.0 uses AES, and RAR's encryption algorithm used to be private. At present, it has not been directly cracked (at least not made public), and there may be only violent cracking without a password.
