ACCDB PASSWORD RECOVERY

ACCDB Password by Thegrideon Software is a feature-rich and highly-optimized
password recovery tool for MS Access 2007 - 2021 & Office 365 databases (.accdb,
.accde, ...). It works with all '.accdb' encryption methods: Agile (SHA + AES),
CryptoAPI (SHA + RC4). Password recovery basics are covered in Password Search
FAQ. You may also check other Access tools for data and VBA source recovery, mdb
tools, etc.

ACCDB PASSWORD RECOVERY FEATURES:

 * All Access 2007-2021 and Office 365 encryption methods are supported.
 * Several password search attacks can be configured and queued:
    * advanced mixed attacks for precise search range setup:
       * multi-position moves to cover modern password policies;
       * simple modifications: add part(s) copy, replace chars, etc.
       * typing errors, case switching, char substitutions;
   
    * brute-force attacks based on a charset and length selected:
       * limit number of equal, capital or special chars or digits;
   
    * dictionary attacks with modifications (several wordlists are included):
       * advanced keyboard layouts-aware recovery technique;
       * password in reverse, capitalized, uppercased, lowercased;
   
    * number ranges (e.g. 1-31, 01-12, 2013-2020, etc.);

 * "Output attacks to a file" option to verify search settings, generate new
   wordlist, etc.
 * Highly optimized code (SSE, AVX, AVX2, AVX-512) guarantees best performance.
 * Utilizes NVIDIA and AMD Graphics processing units with a high-performance
   methods.
 * Utilizes modern Intel integrated GPUs.
 * Supports up to 64 simultaneous processing threads (multi-CPU, multi-GPU).
 * Audio, script or web address based post-search notification.
 * Windows 7 - Windows 11.

PROGRAM SCREENSHOTS:




DATABASE "PASSWORD TO OPEN":

Encryption methods used in Access 2007 are not very strong by today standards
and there is a way to replace database password with guarantee (please check
Access 2007 Password), however there is no way to recover original password
without exhaustive password search.If database password is as important as
database content than ACCDB Password allows you to search through millions of
passwords per second. Password verification methods used in MS Access 2010 -
2021 (and Office 365) are based on industry strong encryption and hashing
algorithms (SHA-1, SHA-512, AES) and instant password recovery or decryption
cannot be guaranteed in contrast to prior MS Access versions. Moreover recovery
speed is limited due to iterative methods used in password verification. Taking
this into account, ACCDB Password is not only equipped with highly optimized CPU
and GPU code, but is also designed for precise search range setup. Several mixed
attacks can be queued to exploit known password details (parts and patterns).
More common dictionary and brute-force attacks with modifications are available
as well.

PASSWORD RECOVERY SPEED:

We did our best to enhance this tool performance as well as the recovery speed
with some advanced methods and it found to be the fastest tool for MS Access
password recovery. Password recovery speed for very common hardware is available
below to back this statement up.

CPU only:
  Access 2007:

Intel® Core™2 Duo
T7500 @ 2.20GHz Intel® Core™ i3
2100 @ 3.10GHz Intel® Core™ i3
4130 @ 3.40GHz Intel® Core™ i7
2600 @ 3.40GHz ~3 000 000 p/s ~6 000 000 p/s ~7 500 000 p/s ~12 000 000 p/s

Access 2010 - 2021:
The final password recovery speed is equal to CPUspeed + GPU(1)speed + ... +
GPU(N)speed.
Access 2010 example: Intel i3 + integrated HD 4400 GPU + AMD R9 280X = 1 000 +
400 + 24 600 = ~26 000 p/s (passwords per second).

CPU:
  Instructions Set: Access 2010: 2013 - 2021:

Intel® Core™2 Duo
T7500 @ 2.20GHz Intel® Core™ i3
2100 @ 3.10GHz Intel® Core™ i3
4130 @ 3.40GHz Amazon EC2 "c5.large"
Xeon® Platinum core SSE2 AVX AVX2 AVX512 ~230 p/s ~475 p/s ~1 050 p/s ~1 200 p/s
~30 p/s ~60 p/s ~135 p/s ~210 p/s

Integrated GPUs
Modern integrated GPUs (like Intel HD and Iris Graphics) can be used for
password recovery acceleration. Integrated GPUs are not as powerful as dedicated
(discrete) devices and often overlooked but can add up to 30% to CPU
performance.

AMD and Nvidia GPUs
Compute units or stream multiprocessors (CU, SM, SMX, SMM) are the main building
blocks of GPU calculation power, thus 32xCU GPU card is usually twice as fast as
16xCU GPU card of the same family and architecture running at the same
frequency.
The table below shows expected performance per SM / CU for Nvidia and AMD GPUs
as well as several actual examples.

NVIDIA GPU: Per SM at 1000 MHz Tesla K80 (Kepler 2.0)
2x13xSMX, 820 MHz Tesla V100 (Volta)
80xSM, 1380 Mhz

Access 2010: 2013 - 2021: 1000-1500 p/s 150-200 p/s 27 000 p/s
27000/26/0.82=1250 3 300 p/s
3300/26/0.82=155 120 000 p/s
120000/80/1.38=1090 18 000 p/s
18000/80/1.38=160

AMD GPU: Per CU at 1000MHz R9 270 (GCN 1.0)
20xCU, 950 MHz RX 480 (GCN 4.0)
36xCU, 1250 MHz

Access 2010: 2013 - 2021: 700-750 p/s 100-150 p/s 13 800 p/s
13800/20/0.95=725 2 400 p/s
2400/20/0.95=125 30 900 p/s
30900/36/1.25=690 5 100 p/s
5100/36/1.25=115

It is important to mention that AMD and NVIDIA architectures are quite different
and although AMD per CU performance is lower, there are more CUs per card in a
similar price range. Moreover GPU performance is somewhat variable with number
of factors including GPU/CPU combination and even a driver version. Please
contact us if your recovery speed is noticeably different from the data above.

TRIAL VERSION LIMITATIONS:

Trial version is available to check format and hardware compatibility. It allows
you to setup and test run any password search for up to 15 min per run.
Recovered passwords are hidden behind the asterisks.
