~How to crack a Hash~



First if you hack some website and get crypted admin password and you don't know what kind of password you get, I suggest you first to read this thread: Hash Types - Must See and you will cracking program. I Recommend you hashcat. Hashcat is advanced password recovery software, It can work on Windows as on Linux, it can crack next hash with these algorithms: 
Code:
MD5
    md5($pass.$salt)
    md5($salt.$pass)
    md5(md5($pass))
    md5(md5(md5($pass)))
    md5(md5($pass).$salt)
    md5(md5($salt).$pass)
    md5($salt.md5($pass))
    md5($salt.$pass.$salt)
    md5(md5($salt).md5($pass))
    md5(md5($pass).md5($salt))
    md5($salt.md5($salt.$pass))
    md5($salt.md5($pass.$salt))
    md5($username.0.$pass)
    md5(strtoupper(md5($pass)))
    SHA1
    sha1($pass.$salt)
    sha1($salt.$pass)
    sha1(sha1($pass))
    sha1(sha1(sha1($pass)))
    sha1(strtolower($username).$pass)
    MySQL
    MySQL4.1/MySQL5
    MD5(Wordpress)
    MD5(phpBB3)
    MD5(Unix)
    SHA-1(Base64)
    SSHA-1(Base64)
    SHA-1(Django)
    MD4
    NTLM
    Domain Cached Credentials
    MD5(Chap)
    MSSQL
    SHA256
    MD5(APR)
    SHA512
    SHA-512(Unix)

Download Link: Hashcat Advanced password recovery


The download is adbove on website. When you download it and extract you will find two files: hashcat-gui32 and hashcat-gui64. Depends on what system you have x64 or x86 you will chose between those. When you chose and open one of that you will be asked what hardware device you like to use. I recommend you to use NVIDIA but you can crack with CPU too. It depends on your PC configuration. Now open a new document in notepad and paste the your hash and save it. Now back top hashcat and follow instructions by numbers

[1] - Here you load your .txt file with your hash inside 
[2] - Chose mode to crack password. You can use Tables or Combination but I think that Brute force is almost guarantied.
[3] - Chose your hash type, repeat if you don't know what is it read this Hash Types - Must See
[4] - Set length of password, here you must guess it. Bigger password longer cracking
[5] - What Charset (words) will be used for password. If you can add your custom if you want, like: !@#$%^&*()_+-ABCDEFG.....
[6] - Finally click start and cracking should begin. The new black command-promt screnn should appear and that means that cracking is in progress. If you want periodically you can press Enter to see the progress of cracking.
