Fgdump hashes are stored in.pwdump file; pwdump6 will dump the SAM to the screen. You can then post the hashes to our cracking system in order to get the plain text. Launch Hash Kracker on your system after installation. Enter the hash text (md5/sha1/sha256/sha384/sha512) for which you want to recover the password. It will automatically display Hash Type for entered hash text. Next select the password dictionary file by clicking on Browse button or simply drag & drop it.
