It is common to find websites that allow registration and the login information consisting of username and password is normally stored in the serverâs 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 hack into the server will instantly have access to thousands of passwords. Other than that, less security minded people will probably use the same password for all online services and this will potentially allow the hacker to gain access to all other services belonging to the user. To solve 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 userâs password to MD5 and storing it on the serverâs database, the hacker wouldnât be able to instantly know your password, even if he managed to access the database. When you login, it simply needs to convert your password that you entered in your web browser to MD5 and compare it in the database. If it matches, then youâre allowed to log in. This also improves the password recovery function by sending a newly generated password rather than allowing you to 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 âpasswordâ will always match the MD5 â5f4dcc3b5aa765d61d8327deb882cf99â. MD5 is weak and many online applications such as WordPress no longer store password as MD5 hashes their database. So is there a way to decrypt MD5? Although not directly, it is possible to perform a reverse lookup. Here are 10 websites containing huge databases that offer online services to check if there is a matching string for a given MD5. As a simple test, weâve tried searching a simple MD5 of the string âraymondâ and all of them successfully found the string in their database. As for the second round of tests, we appended .cc at the end of the string raymond and only 1 MD5 decrypt service that weâve listed at the end of this article managed to find the result in their database.1. md5online.org md5online.org contains 452 billion words in their database. Other than searching for the original word of the MD5 from the website, you can also request for a batch search which is limited to 100 lines and the results will be sent to the provided email address. They also provide a simple API for paid premium members where their service can be used to decrypt MD5 from a script, website or even application. Visit md5online.org 2. md5crack.com Unlike most of the online websites that have their own database of MD5 and words, md5crack.com uses a combination of search engine indexes and rainbow tables to help search for a word matching the given MD5 hash. Free API usage without limitations is also available to everyone although the usage is closely monitored to prevent excessive use. Visit md5crack.com 3. md5cracker.org md5cracker.org 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 donât work anymore. It is still useful because the results are shown in real time without the need to refresh the webpage. Visit md5cracker.org 4. md5decrypt.org Similar to md5cracker.org above, md5decrypt.org claims to search your hash on over 23 other websites for a matching word. It is hard to tell whether md5decrypt.org did crawl over 23 website to search for a matching word because it does not list the other websites being used and the search is very quick, that always takes nearly the same amount of time to return a result. Visit md5decrypt.org 5. crackstation.net crackstation.net is a password hash cracker that can automatically recognize different types of hash functions other than MD5 and search for the correct password for the given hash. It is able to accept up to 10 hashes at a time and uses their own wordlist consisting of every word found in Wikipedia and every password list that they could find. Other than that, theyâve also made their wordlist more efficient by applying intelligent word mangling. Visit crackstation.net 6. hashkiller.co.uk Hashkiller.co.uk has been around since 2007 and has decrypted over a whopping 43 billion MD5 hashes to date! The decryption form accepts up to a maximum of 64 MD5 hashes to check at a time. They have a public forum which is very helpful because anyone can sign up for a free account and post a hash cracking request as long as it is below 25 hashes. Visit hashkiller.co.uk 7. reverse-hash-lookup.online-domain-tools.com Online Domain Tools is a website that provides many useful tools that can be used for networking, domain, web, browser, security, privacy, data, conversion, and coding purposes. One of their tools is a reverse hash lookup that can decrypt MD5, SHA1, SHA-256, LM and NTLM hash function to plaintext message. The form allows up to 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. Visit reverse-hash-lookup.online-domain-tools.com 8. md5decrypt.net md5decrypt.netâs database contains over a billion words but still is not considered to have one of the biggest wordlists. However, what we like about md5decrypt.net is the clean design with no advertisements at all and the ability to search for words that are hashed twice. A useful tip is the text box can actually support multiple hashes up to a maximum of 500 by putting each hash in a new line. Visit md5decrypt.net 9. onlinehashcrack.com onlinehashcrack.com is a slightly more professional service to crack your hash. A few techniques such as Rainbow, Hybrid, Wordlists, and Bruteforce are being used to crack a hash. Any cracked hash containing 8 or more characters will require a payment of 3⬠to reveal the password while anything below 8 characters is free. You will need to enter a valid email address to receive a notification when the cracking process has been completed and to access a private URL containing the result. Apart from cracking MD5 hashes, they can also crack WPA/WPA2 in *.cap or *.pcap file extension. A useful hash identification service is useful to determine the type of hash being used. Visit onlinehashcrack.com 10. cmd5.org cmd5.org claims to have the largest database in the world with 7.8 trillion unique records. They are similar to onlinehashcrack.com whereby they offer both a free and paid hash cracking service. Although not mentioned anywhere on their website, it seems like a cracked hash containing 6 characters or less is free while strings containing 7 characters or more require payment. Their cheapest package is they accept a minimum payment of $20 that includes 1000 hashes with no expiration to the credits. This is the only one that managed to decrypt the MD5 of the word âraymond.ccâ.

Great work, as usual Raymond. At first I thought no drug would fry a mans brain quite like Flash. That was two years ago before I learned about encryption, hashes, salts and algorithms. Havenât slept much since then. The stuff is addicting if youâre a numbers junkie like myself. The site list of MD5âs is awesome. Iâll keep searching and see if I can find a few more for you. ReplyThanks brother i really need this tut because i was really want to know about MD5.Thanks again. Reply

A lot of MD5 hash âdecryptionâ services employ the use of Rainbow Tables. Essentially these are massive lookup tables. One method I use to create massive lookups, is simply to start generating them starting from aaaaa to zzzzz. ReplyGreat post Raymond ! :) Really helpful.

Quite difficult to understand the encryptiondecryption but nice to know for General Awareness sake as I never use WordPress Even Though Thanx Raymond ReplyLeave a ReplyDecrypts lost or forgotten passwords to popular VNC server applications, featuring automatic and manual recovery modes, along with export optionsWhat's new in VNC Password Recovery 4.0:
VNC Password Recovery is an approachable Windows utility developed to retrieve lost or forgotten passwords to VNC server programs, such as UltraVNC, TightVNC and VNC. It features highly intuitive settings to please both types of users, whether they are experienced with data recovery software or not. Automatic or manual key recoverySo, you can select the recovery mode between automatic and manual. While the first method is self-explanatory since it automatically detects the installed VNC server app, the second one lets you input a password to decrypt with the click of a button. The primary window shows the location and key for each VNC utility identified, and lets you export data to an external file for further evaluation and safekeeping. There are no other notable options provided by this software tool. Evaluation and conclusionCPU and RAM consumption was minimal during our evaluation, and VNC Password Recovery did not hang, crash or pop up error messages. We have not come across any unpleasant surprises. It recovers VNC passwords almost instantly and features intuitive options for all user groups. Those who want to skip the installer and run the app directly from a removable storage unit may use VNC Password Recovery Portable instead of its installer counterpart.

Welcome back, my fledgling hackers! There's an evil dictator hellbent on destroying the world, and in one of our last hacks, we successfully compromised his computer and saved the world from nuclear annihilation. Then, we covered our tracks so no one would know what we did, and developed a hack to capture screenshots of his computer periodically so we could track of what he was up to next. With this new hack, we'll capture the passwords from the maniacal dictator's computer so that we can access his PC through his accountâ or anyone else's account on his computer, including the most important accountâthe system administrator's.

If you're new to Linux or Unix, you might prefer using a graphical user interface (GUI) over the command-line interface (CLI), and when remotely connecting you can use the remote desktop protocol and GUI-based Virtual Network Computing (VNC). Some Linux distros come with a VNC server pre-installed and for others you'll probably find plenty of tutorials on how to get started, so we'll skip the basics and share some security tips. As a result, for this tutorial we assume you already have a VNC server installed and running on a Linux/Unix machine. Securing VNC with SSHWhile VNC implements some sort of encryption for the login process, it's not fully secure and the login password could be sniffed and cracked by people on the local network or Internet. Plus the actual VNC sessions aren't encrypted at all. To fully secure your VNC sessions you can tunnel the traffic through a SSH connection to the server. To do so, you'll first want to set up an SSH server and open the SSH port 22 on the machine you're trying to remotely access. Then on the computer you're remotely connecting from you can set up a port forward in the SSH client. Here's how you'd configure the port forward when using the PuTTY SSH client:
Now you can connect to your server via SSH, and while connected you can open your VNC client and connect to 'localhost.' Once successful, you may want to consider closing the VNC port (probably 5901) on your Linux machine if you had previously connected directly via the Internet. Changing the VNC PasswordIf you'd like to change your VNC server's password in Linux you can use the vncpasswd command, which is the same command that's run by the vncserver script the first time you start a VNC desktop. This command will change and/or store an obscured version of the password to the password file by default at Since it's not securely encrypted, keep in mind that anyone with access to the password file could convert it to plain text and reveal the password. When you're ready to change the password, enter the following command in the Terminal, either on the machine directly or remotely using a SSH client like PuTTY: You'll be prompted twice to enter the new password, which should be between six and eight characters long. Then restart the VNC server by killing the VNC session/display: Then you can start the VNC session or display again by entering: Eric Geier is a freelance tech writer.
