Ultrafast Cracking
Multi-core and multi-GPU support takes optimal advantage of your
hardware. Whether you have a single CPU with dual cores or an 8 CPU
machine with 24 cores each, L0phtCracks multithreaded processing will
utilize every last bit of your CPU. If you have one or more GPUs, whether
NVIDIA or ATI, L0phtCracks OpenGL and CUDA support, opens the potential
for billions of cracks per second depending on the power of your GPU.


L0phtCrack also takes the guesswork out of which type of processor and
instruction set is fastest with our calibration process. When you first
launch L0phtCrack it runs a calibration test. L0phtCrack cycles through
all the hash types with each processor and algorithm to determine the
fastest one for each hash type. Some hashes are fastest with the CPU and
others the GPU. The fastest is stored. If you change your hardware, such
as adding an additional GPU you can re-run the calibration process.


Simple Password Loading
Wherever your password hashes are: local, remote, AD, or in a file. Its
simple to import them for auditing with our wizard. The L0phtCrack wizard
makes it easy to step through the process of retrieving the password
hashes for the accounts you want to audit. You dont have to scramble to
find and learn a separate command line tool that may not even support the
latest Microsoft Windows version and hotfix. Password importing from a
local or remote machine is built in and is as easy as entering a machine
name and credentials into a form field.


Easy to customize
Custom word lists, character sets, and lengths are easy to set. Crack the
way you want and save the settings for later. The audit settings panel
lets you select a standard character set, such as alphanumeric or UTF-8,
or you can create your own. You can even use different character set for
different hash types. The min and max password length can also be
selected. The settings you select can be saved for later.


Remediation
Fix weak passwords by forcing password resets or locking out accounts.
If you are auditing a local or a remote Windows machine you no longer have
to switch programs to remediate accounts with easily crackable passwords.
Run your audit and remediate the accounts with weak passwords right from
L0phtCrack. Select the weak accounts and right click to force password
resets or lock our accounts.


Powerful scheduling
Schedule sophisticated tasks for automated enterprise-wide password
audits. Whether you are auditing to reduce risk or meet compliance
regulations, periodic password auditing is a must. With L0phtCrack you
can automate recurring audit tasks so that you simply end up with an
export of cracked accounts on a weekly, monthly, quarterly, or annual
basis. You can set up as many import, auditing, and reporting actions as
you want in a queue and then run that queue on a schedule.


Audit multiple OSes
Windows plus 1st rate Linux, BSD, and AIX support. L0phtCrack supports
all versions of Windows between Windows XP and Windows 10 and many
flavors of UNIX. In addition there is a flexible plugin system that will
allow 3rd parties to supply support for additional password hash types
and import mechanisms.
