We have covered quite a lot of Password Cracking tools and it’s not often a new one comes out, this one is for quite a specialised purpose (not a general all-purpose password cracker like John the Ripper or Cain & Abel), although you do need to use it alongside JTR.
Md4 Hash Cracker Online
This tool is for instantly cracking the Microsoft Windows NT Hash (MD4) when the LM Password is already known, you might be familiar with LM Cracking tools such as LCP.
The main problem is you’ve got the LM password, but it’s in UPPERCASE because LM hashes are not case sensitive, so you need to find the actual password for the account.
Example : Password cracker output for “Administrator” account
- LM password is ADMINISTRAT0R.
- NT password is ?????????????.
We aren’t lucky because the case-sensitive password isn’t “administrat0r” or “Administrat0r”. So you cannot use this to connect to the audited Windows system.
This password contains 13 characters but launching my password cracker on the NT hash is a waste of time and there is a poor chance of success.
Note :
- Password length : 13 characters.
- Details : 1 number + 12 case-sensitives letters.
- Possibilities : 2^12 = 4096 choices.
In this example, lm2ntcrack will generate the 4096 possibilities for the password ADMINISTRAT0R and, for each one, the associated NT MD4 hash. Then, search for matching with the dumped hash.
Execution time : < 2 seconds to crack more than 1200 NT Hashes.You can download lm2ntcrack here:lm2ntcrack-current.tgz

Usage from Address Bar
You can use direct access to this page from your browser address bar. Type string that you need to encode with algorithm according to next schema: https://md5calc.com/hash/<ALGORITHM>/<PHRASE>
For example to visit page that contains hash of 'hello world' you can just visit url: https://md5calc.com/hash/md5/hello+world
The another cool thing is that you can specify 'json' or 'plain' mode into URL and you will get only HASH in response. Schema of this future: https://md5calc.com/hash/<ALGORITHM>.<OUTPUT:plain|json>/<PHRASE>
Example: https://md5calc.com/hash/md5.json/hello+world
Will output only: '5eb63bbbe01eeed093cb22bb8f5acdc3'
If you have string that contains complicated urlencoded characters you can send it directly via params to avoid processing of our url parser. Use:
str - for string to encode
algo - for algorithm
output - for output type (empty, 'json' or 'plain')https://md5calc.com/hash?algo=<ALGORITHM>&str=<PHRASE>&output=<OUTPUT:plain|json>
https://md5calc.com/hash?algo=md5&str=hello%0Aworld
https://md5calc.com/hash/md5?str=hello%0Aworld
Usage from Javascript
We have removed CORS restriction so you can use direct access to hash calculator in your javascript applications via AJAX.
Example: Will output: JSON of 'hello world' is '5eb63bbbe01eeed093cb22bb8f5acdc3'
Usage from PHP
You can use direct access to hash in your applications.
PHP Example: <?php
Will output:
$str = 'hello world';
$url ='https://md5calc.com/hash/md5.plain/'.urlencode($str);
$md5hash = file_get_contents($url);
echo 'Hash of '.$str.' is '.$md5hash.''; Hash of 'hello world' is '5eb63bbbe01eeed093cb22bb8f5acdc3'
Keep in mind that this example no make sense because PHP has builtin function hash() which do the same.
Chains of algorithms
In some cases you can need encode string with two or more algorithms. For these cases we have introduced chains of algorithms. For example if you need to encode string according to this schema md5(sha512(sha1('hello world')))
you can do this by connecting algorithms with a double dash: https://md5calc.com/hash/md5--sha512--sha1/hello+world
If you will do this in your address bar you can also use semicolon instead of double dash. https://md5calc.com/hash/md5;sha512;sha1/hello+world
Pay attention that semicolon should be encoded in url, so if you use it not in your browser, you should use '%3B' instead https://md5calc.com/hash/md5%3Bsha512%3Bsha1/hello+world
Such approach can be also used with 'plain' and 'json' mode https://md5calc.com/hash/md5--sha512--sha1.plain/hello+world
https://md5calc.com/hash/md5;sha512;sha1.json/hello+world
Md4 Hash Cracker Game
You can also use special chain item 'b64d' or 'base64decode' to make base64 decode. It can help to hash any of not printable characters. Example: https://md5calc.com/hash/md5.plain/hello+world
https://md5calc.com/hash/b64d--md5.plain/aGVsbG8gd29ybGQ=
will be the same: 5eb63bbbe01eeed093cb22bb8f5acdc3
At present time you can use it only through url..
Carriage Return and Line Feed characters
Md4 Hash Cracker Recipes
At present time our text editor doesn't have functionality that can take into account which of those characters you want to keep in string. This problem come from browsers which normalize all of the line endings to 'CRLF' ('rn') format according to 'HTML specification'. It means that if you paste from buffer string'hellonword'
and press 'Encode', your browser will convert it to 'hellornword'
and only after this your browser send FORM to us. As a result we will show you hash of 'hellornword'
but not 'hellonword'
Md4 Hash Cracker
You can avoid this with encode string to 'base64' on your side and use 'Chains of algorithms' that described above.
Example 1: Hash from string with only Line Feed (LF) character Text: hellonworld
Text encoded to BASE64: aGVsbG8Kd29ybGQ=
URL: https://md5calc.com/hash/b64d--md5.plain/aGVsbG8Kd29ybGQ=
RESULT: 9195d0beb2a889e1be05ed6bb1954837
Example 2: Hash from string with Carriage Return (CR) and Line Feed (LF) character. This result you will have if you use editor with CR, LF or CRLF symbols. Text: hellornworld
Text encoded to BASE64: aGVsbG8NCndvcmxk
URL: https://md5calc.com/hash/b64d--md5.plain/aGVsbG8NCndvcmxk
RESULT: 6a4316b18e6162cf9fcfa435c8eb74c1
