go build -o dehash
./dehash -hash aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d -charset abcdefghijklmnopqrstuvwxyz

Usage

./dehash -hash hexstring|-file path [-type md5|sha1|sha256|sha512|sha3-256|sha3-512|blake2b256|blake2b512|blake2s256|groestl|jh] [-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")
