RAR archiver
RAR archiver, developed by Eugene Roshal, uses a very strong encryption algorithm. Encryption key is 128 bits long. 256 bytes S-Box is derived from each key. S-Box operations are very complicated and slow. Known-plaintext attack is not possible at all. Only brute-force or dictionary attack can be used for password recovery. Recovery speed is very low; for example, we can test only about 4800 passwords per second on P-III 800.
