Hash Crack is a software program for hashes and passwords cracking.
Hash Crack use dictionary or set of symbols for hashes cracking, and also support pwdump file format for Windows passwords cracking NTHash MD4.
Features
- Crack list of hashes or pwdump file format for MD4 NTHash
- Hash functions: MD2, MD4, MD5, SHA1, SHA256, SHA384, SHA512
- Crack with dictionary text file
- Crack with set of symbols
Hash cryptographic function is a one way function that creates hash from some value and cannot be reversed.
For example MD4 hash function for value password1 creates hash E2E0D780CC30CCFBD1BBCF196B97A735 and it is one way function, it is not possible from the hash to get back to value password1.
Hash functions are used also in information technology security, for cryptography, communication, password storage …
Windows operating systems store user passwords in hash format, when the user first time creates password the operating system transform the password with hash functions LM and NT(MD4) and save the hashes to the system registry.
These hashes can be extracted with programs as pwdump.exe http://en.wikipedia.org/wiki/Pwdump
Example of usage and result of pwdump.exe, the right most hash is NTHash (MD4).

Hash cryptographic function is a one way cannot be reversed, but the hash can be cracked creating hashes from different values for example from dictionary and comparing generated hashes with the target hash.
