What are the Chances of Recovering a Lost Password?
You can try a free check for weak passwords: it is successful in about 22% of all cases, and it takes only one or two minutes to see the result.
If the password is not recovered with a free check, you will be offered a paid option to try a 20+ billion passwords database check. This is our "nuclear weapon," and a search through such a huge database may take up to 24 hours, depending on the file version and our computing cluster workload. Your chances to recover the password successfully are about 61% in this case.
Here is more information about the password recovery chances.
How to Remove the Password From the Zip archive?
If you already know the password to the archive, it is simple. Actually, you can't remove password protection from an already protected Zip archive with WinZip program. But you can extract archive to a folder, and then add all files to a new Zip archive without password.
If you do not know the password, you need to recover it first. Upload the file to our website and wait until we complete the work.

We have to inform that there is no magic wand software to uncover encrypted data. Most people don’t expect recovering the password to encrypted documents to be a very slow and resource-intensive process but it is. Below, we explain in simple words what the password recovery procedure is and how it works on our cloud service.
How to recover a lost password
Let us assume that you accidentally lost the password to a protected file of yours and you want to restore the password.
First, you shouldn’t waste your time trying to find a program for hacking protected files easily because such programs don’t exist. All modern software like MS Office use cryptographic algorithms to encrypt data; the stability of these algorithms is proved mathematically.
So, the password recovery procedure is a long search through a huge number of variants for a proper password. Just for you to imagine the scale of the work: there are more than 60 quintillion (60 * 1018) variants of 10-character passwords. That number reflects only passwords that were made up of English alphabet letters, numbers and special signs. If there is the Greek alphabet and other symbols to choose from, the number of possible variants will increase even more, so, that even a supercomputer couldn’t handle a direct search (the so-called brute force method) through such a large number of possible passwords within a reasonable period of time because a testing procedure for each possible password needs complex mathematical calculations that require significant processor time and power. The more complex the encryption algorithm is, the slower the password search process.
Recover passwords by a dictionary
But things are not as bad as they seem to be. People usually choose an “easy to remember” password, which makes it easier to recover. A great number of commonly used passwords have a simple, readable form or are compiled according to certain rules. These are common words like “shadow,” pet nicknames, word combinations like “letmein,” words plus numbers like “John1234,” dates of birth, easy combinations of digits like “654321,” letter neighbors on the keyboard like “asdcxz,” and other types of passwords that are easy to remember for almost anyone.
There are not many of these types of combinations compared to the 60 quintillion total possibilities, which greatly simplifies our task. At the moment, we have collected a database of more than 20 billion commonly used passwords for brute force cracking. This passwords database gives us a good chance, but it still does not guarantee 100% success. Nevertheless, we successfully find the password in more than half of the cases, which is a good result.
As a bonus for our visitors, we try to recover your password for free with our dictionary of the 3 million most popular passwords. The probability of a successful password recovery is lower than using our large database, but this attempt is carried out almost instantaneously and still has a good chance for success.
If a quick search through the most popular passwords is not a success, then we use the whole database for the search and it can take up to 24 hours.
Brute force passwords with a mask
If you know the structure of the lost password, you can search through all the possible passwords using a mask. For example, if you know that the password consists of 8 or 9 characters, starts with “999,” and the remaining characters are letters of the English alphabet in lowercase, then that makes the search process much easier. In this case, the total number of all possible variants is 333,629,036. Our computing cluster will brute force such a protected file in just a few minutes.
Brute-forcing a password with a dictionary is a fixed-cost work, but brute-forcing with a mask is a custom task. You may use the custom request page to describe everything you know about the lost password: the expected length and character set, etc. Perhaps, you know characters that your password begins or ends with. We can create masks with these criteria, calculate the total number of possible password variants and let you know about the work cost.
Note that it would be a pre-paid work and the success is guaranteed only if the specified mask parameters were correct. If you make a mistake describing the password structure (for example, the password was actually longer and/or contained characters outside the specified set), then the composed mask won’t help to find it. However, the work was done and the payment is not refundable. Use the brute-forcing by mask only when you are sure about the exact password structure!
Can I recover the lost password with my home computer?
Actually, no. Surely, you can try some password recovering programs on your computer, but mind some important facts:
Most of these programs are shareware. In a free mode, they will allow you to search for a password of a very limited length (usually no more than 4 characters). A sophisticated user would successfully try such a program and purchase it hoping to crack much longer passwords. But the number of possible variants with longer passwords grows not linearly, but exponentially. For example, cracking a 4-character password process is a search through only 15 million alphanumeric variants. A 5-character password has 931 million possible variants (62 times more), and a 6-symbol one has about 58 billion. This is a hard task even for a very powerful computer, so don’t even try to crack a 7-character password.
The power of a cracking program is limited by your computer’s resources. In our cloud system, we have a powerful cluster of high-performance GPU-servers. This is a distributed computing system. In other words, passwords are recovered by several powerful servers at the same time, and we can perform in a few hours the work that would take months or even years for a modern home computer to do it. For more information, visit the “Our infrastructure” page.
A shareware program doesn’t contain a good password dictionary. All it can do is to produce a combined attack: combining words and numbers from a small dictionary and changing the case of letters. It takes a long time, and it only helps to crack the easiest of passwords.
Last, but not least, when buying a cracking program, you have to pay in any case, even if the password is not found. We only charge for a successfully found password. Fast, guaranteed and convenient.
Instant password recovery
It generally refers to the rapid recovery of password if it is weakly encrypted. An example would be the password for the Access database or older word or excel files.
Password reset
In some cases there is a possibility to reset the password by replacing or deleting them from the file directly.
Brute-force attack
It is the most common method of decrypting files. This attack simply tries every combination of characters in a given set to try to recover your password. To recover a password consisting of `a` lowercase letter for example, 26 combinations are needed (from 'A' to 'z'). In the case of two letters we have 26x26 = 676. We are dealing with exponential growth so as automatic password combination is higher so password recovery is more difficult. Certainly the combination can have capital letters, numbers or special characters, in this case a long passwords recovery can be done in days or weeks (depending on length). We use specialized software to distribute the computing power on multiple servers, thus significantly reduces password recovery time.
Dictionary attack
This method of recovery uses a dictionary. Specialized software tries every word in the dictionary as the password. Besides the common words a good dictionary contains some commonly used combinations in passwords like 'qwerty'. Dictionary password recovery method is usually much faster than brute-force attack. Of course if the dictionary is large password recovery will be slower, but this method is usually used before a brute-force password recovery. There are different ways of combining the two types of recovery mentioned (hybrid methods).
Variation in password
This recovery method is usually used when the password was probably typed wrong. Usually the user knows the password contained a certain word and maybe some numbers. Or maybe the password was mistyped, or a character was omitted. Usually the number of combinations is low and the password will be quickly recovered.
Plain text password attack
This method is most commonly for zip archives protected by password. Password Recovery is easier when partial of the archive contents is known. For example, we know some of the encrypted files inside the archive. Or perhaps archive contains certain standard DLLs can be found inside the Windows or unencrypted on internet.
Answers to Questions (FAQ)
What is a zip password? (Definition)
A Zip file is a file format for archiving other files with compression. The files contained in the archive can be protected by a password. This is the password for the Zip file.
How to find the password of a Zip file?
The only way to recover a Zip password is to test them all.
Select the Zip file on your device and click Find.
How to speed up password search?
The search is a time-consuming job (usually several hours), it is recommended to limit the search according to the size of the password, and the characters used.
Example: A 3-character password containing only lowercase letters requires 17576 attempts, while it will require 238328 attempts (13 times more) if it consists of uppercase, lowercase and digits.
dCode uses the resources of your browser and your device, the more powerful it is, the faster the calculations will be.
NB: This Zip cracker is a free and online tool, there are applications (sometimes paid) to install on your computer/phone which will not be limited by the browser and therefore probably more effective.
How does Zip password cracker work?
The tool creates the list of possible passwords based on the selected characters and the assumed length of the password and attempts to extract a file from the zip archive.

ВОССТАНОВЛЕНИЕ ДОСТУПА ЗА МИНУТУ
Иногда защиту с архива можно снять всего за минуту. При наличии хотя бы одного файла из архива ZIP или ARJ весь архив целиком может быть вскрыт за минуту с использованием атаки при известных данных. Архивы ARJ в подобной ситуации расшифровываются мгновенно. Восстановление доступа за минуту возможно только в случае с "классическим" шифрованием, а не AES.
ГАРАНТИРОВАННОЕ ВОССТАНОВЛЕНИЕ ДОСТУПА К АРХИВАМ WINZIP 8.0
Если архив защищен стойким паролем, его расшифровка может занять много времени. Некоторые архиваторы содержат уязвимости, позволяющие расшифровать созданные ими архивы гораздо быстрее. Так, при вскрытии архивов, созданных архиватором WinZip версий 8.0 и более ранних, возможна гарантированная расшифровка в течение часа. Для того, чтобы это стало возможным, требуется наличие в архиве хотя бы пяти файлов. Гарантированное восстановление возможно только в случае с "классическим" шифрованием, а не AES.
ВОССТАНОВЛЕНИЕ ДОСТУПА К АРХИВАМ, ЗАЩИЩЁННЫХ AES И ДРУГИМИ СИЛЬНЫМИ АЛГОРИТМАМИ
Современные архиваторы используют стойкие алгоритмы защиты, такие как американский государственный стандарт шифрования AES. Использование AES с 128- и 256-разрядными ключами архиваторами WinRAR и последними версиями WinZip обеспечивает повышенную стойкость защищённых архивов. В случае использования сильной защиты с помощью Advanced Archive Password Recovery возможно подобрать оригинальный пароль к архиву. Программа комбинирует различные способы атак с целью скорейшего восстановления паролей.
ПЕРЕБОР ПО МАСКЕ
В случае наличия дополнительной информации о пароле (известна длина пароля в символах или любая часть пароля, либо есть информация об использовании или отсутствии в пароле определенных символов и цифр) скорость восстановления может быть существенно увеличена методом перебора по заданной маске.
АТАКА ПО СЛОВАРЮ
Согласно статистике, существенная часть паролей, используемых для защиты архивов, содержит одно или несколько слов из словаря. Метод подбора паролей по словарю позволяет в десятки раз сократить время, требуемое для восстановления пароля. Advanced Archive Password Recovery поддерживает атаку по словарю, перебирая пароли, состоящие из слов и их возможных комбинаций в разных регистрах и на нескольких языках. Поддерживается возможность подключения дополнительных словарей.
ПРЯМОЙ ПЕРЕБОР
В случае полного отсутствия информации о пароле осуществляется перебор всех возможных вариантов пароля определенной длины для восстановления доступа к документу. В Advanced Archive Password Recovery используются новейшие методы низкоуровневой оптимизации кода под современные процессоры, позволяющие достичь высокой производительности перебора по сравнению с конкурирующими продуктами.
