It supports the 44 hash-algorithms (MD4, MD5, NTLM, DES, MD2, Adler, CRC, XOR, GOST, Haval, Panama, RipeMD, SHA, Sapphire and others), and 4 progressive attack methods: Bruteforce Attack, Dictionary Attack, Hybrid Attack and the method of a Typing Mistake Correction (the effective method of the recovery of the partially-known password).UDC can be used also as universal hash-library with open API; it could be easily expanded by the user-designed implementation of an any cryptographic method.The main benefits of the program are the high speed of the Bruteforce Attack and the method of the Distributed Attack, which allows translation of a standard local network into powerful distributed cluster.The speed of the NTLM Bruteforce (Windows password) is about 1.600.000 password per second, the Dictionary Attack speed is more than one million words per second; the Hybrid Attack cracking rate is 1.500.000 combinations per second in average (tested on Celeron-433).The program is optimized for the "mass cracking", i.e. searching the password for unlimited amount of hashes at once, practically without decreasing of the search speed.

UDC has the friendly and useful graphical interface and a lot of additional powerful features to use.
