Using Hashlecter

Command-line arguments

Short	Long	Type	Description
-a	--alphabet	Argument	Specify the bruteforce alphabet
-i	--input	Argument	Read hashes from file
-d	--dict	Argument	Perform a dictionary-attack using the specified file
-s	--session	Argument	Specify a session name
-r	--rounds	Argument	Specify hashing rounds
-l	--len	Argument	Specify the max length of the generated string
-g	--gen	Switch	Generate a hash
-fupper	--force-upper	Switch	Force uppercase hashes
	--incremental	Switch	Incremental bruteforce mode
	--stdin	Switch	Read hashes from stdin
	--silent	Switch	Don't output anything to stdout
	--wizard	Switch	Easy configuration
	--show	Switch	Show results; can be combined with -s/--session

Info:
The default hashing method is md5.
If you want to generate a hash, just specify the input string using -i/--input

Important:
The -r/--rounds argument doesn't work with variations of hashes.
If you want to try 6-round md5, do -r 6 -m md5, but not -r 3 -m md5_double.

Experimental/Unstable features

Short	Long	Type	Description
	--exp-lazy-eval	Switch	Lazy evaluation of input dictionary
	--exp-single-cont	Switch	Don't stop after finding a collision

Examples (mono)

Cracking the md5 hash for "hello" using dictionary "dict":

# mono lecter.exe -d dict --stdin | echo 5d41402abc4b2a76b9719d911017c592

Cracking a list "hashes" of 2-round md5-hashed entries using dictionary "dict":

# mono lecter.exe -d dict -i hashes -r 2

Bruteforcing the md5 hash for "hello" using incremental mode and a lowercase alphabet:

# mono lecter.exe -a $l --incremental --stdin | echo 5d41402abc4b2a76b9719d911017c592

Examples (Microsoft .Net)

Cracking the md5 hash for "hello" using dictionary "dict":

> lecter.exe -d dict --stdin | echo 5d41402abc4b2a76b9719d911017c592

Cracking a list "hashes" of 2-round md5-hashed entries using dictionary "dict":

> lecter -d dict -i hashes -r 2

Bruteforcing the md5 hash for "hello" using incremental mode and a lowercase alphabet:

> lecter -a $l --incremental --stdin | echo 5d41402abc4b2a76b9719d911017c592
