Simple multithreading brute hash MD5, SHA128, SHA256 and SHA1.

Usage

./dehash -hash hexstring|-file path [-type sha1|sha256|sha512|md5] [-max val] [-min val] [-charset chars] [-threads num] 

Usage of ./dehash:
-charset string
      char set for possible message (default "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\v\f")
-file string
      path to file with hashes
-hash string
      hash to be decrypted
-max int
      max length of message (default 10)
-min int
      min length of message (default 1)
-threads int
      max number of threads (default 256)
-type string
      hash algorithm (default "sha1")
