Online password hash crack

It is comtháng khổng lồ find websites that allow registration & the login information consisting of username và password is normally stored in the server’s database. Many years ago, passwords stored in database were clear text which is why it is possible to recover lost passwords. This is obviously unsafe because a hacker that manages to hachồng inkhổng lồ the server will instantly have sầu access khổng lồ thousands of passwords. Other than that, less security minded people will probably use the same password for all online services và this will potentially allow the hacker lớn gain access lớn all other services belonging khổng lồ the user.

To solve sầu this problem, a type of cryptographic hash function called MD5 had been introduced which was deemed safer at that time because it is a one way process. By converting the user’s password khổng lồ MD5 và storing it on the server’s database, the hacker wouldn’t be able to instantly know your password, even if he managed khổng lồ access the database. When you login, it simply needs khổng lồ convert your password that you entered in your web browser to lớn MD5 & compare it in the database. If it matches, then you’re allowed lớn log in. This also improves the password recovery function by sending a newly generated password rather than allowing you khổng lồ recover your old password.

Although MD5 is a one way process that cannot be programmatically decrypted, it is still possible to build a database or dictionary file containing MD5 hashes that matches a string because a string will always match the same MD5. For example, the string “password” will always match the MD5 “5f4dcc3b5aa765d61d8327deb882cf99”. MD5 is weak and many online applications such as WordPress no longer store password as MD5 hashes their database.

So is there a way khổng lồ decrypt MD5? Although not directly, it is possible lớn perkhung a reverse lookup. Here are 10 websites containing huge databases that offer online services to lớn check if there is a matching string for a given MD5.
As a simple demo, we’ve tried searching a simple MD5 of the string “” và all of them successfully found the string in their database. As for the second round of tests, we appended .cc at the over of the string và only 1 MD5 decrypt service that we’ve sầu listed at the over of this article managed khổng lồ find the result in their database.


* contains 452 billion words in their database. Other than searching for the original word of the MD5 from the trang web, you can also request for a batch tìm kiếm which is limited to lớn 100 lines and the results will be sent khổng lồ the provided gmail address. They also provide a simple API for paid premium members where their service can be used khổng lồ decrypt MD5 from a script, trang web or even application.




Unlike most of the online websites that have their own database of MD5 và words, md5craông chồ uses a combination of tìm kiếm engine indexes và rainbow tables lớn help tìm kiếm for a word matching the given MD5 hash. Free API usage without limitations is also available to lớn everyone although the usage is closely monitored khổng lồ prsự kiện excessive sầu use.



* shows that it automatically searches 11 different websites for a matching word of a provided MD5 hash. However after manually testing each database, we found that half of them don’t work anymore. It is still useful because the results are shown in real time without the need lớn refresh the webpage.

Similar to lớn above, claims khổng lồ tìm kiếm your hash on over 23 other websites for a matching word. It is hard khổng lồ tell whether did crawl over 23 website to tìm kiếm for a matching word because it does not danh mục the other websites being used và the search is very quiông chồng, that always takes nearly the same amount of time to return a result.



* is a password hash cracker that can automatically recognize different types of hash functions other than MD5 and tìm kiếm for the correct password for the given hash. It is able lớn accept up to 10 hashes at a time and uses their own worddanh sách consisting of every word found in Wikipedia và every password các mục that they could find. Other than that, they’ve also made their wordlist more efficient by applying intelligent word mangling.



* has been around since 2007 và has decrypted over a whopping 43 billion MD5 hashes lớn date! The decryption form accepts up lớn a maximum of 64 MD5 hashes lớn kiểm tra at a time. They have a public forums which is very helpful because anyone can sign up for a không tính phí account and post a hash cracking request as long as it is below 25 hashes.




Online Domain Tools is a trang web that provides many useful tools that can be used for networking, tên miền, web, browser, security, privacy, data, conversion, và coding purposes. One of their tools is a reverse hash lookup that can decrypt MD5, SHA1, SHA-256, LM and NTLM hash function to lớn plaintext message. The size allows up to lớn 5 hash values at a time and the result is shown instantly at the bottom of the form. The lookup is based on several online databases as well as engines using rainbow tables.



*’s database contains over a billion words but still is not considered khổng lồ have sầu one of the biggest wordlists. However, what we like about is the clean thiết kế with no advertisements at all and the ability khổng lồ tìm kiếm for words that are hashed twice. A useful tip is the text box can actually support multiple hashes up khổng lồ a maximum of 500 by putting each hash in a new line.

* is a slightly more professional service khổng lồ craông chồng your hash. A few techniques such as Rainbow, Hybrid, Wordlists, và Bruteforce are being used khổng lồ crachồng a hash.

You will need khổng lồ enter a valid gmail address to lớn receive sầu a notification when the cracking process has been completed and khổng lồ access a private URL containing the result.


Apart from cracking MD5 hashes, they can also craông chồng WPA/WPA2 in *.cap or *.pcap file extension. A useful hash identification service is useful to lớn determine the type of hash being used.

Their cheapest package is they accept a minimum payment of $đôi mươi that includes 1000 hashes with no expiration lớn the credits. This is the only one that managed khổng lồ decrypt the MD5 of the word “”.
