Here are 5 free Playfair cipher solver websites to decode encrypted message. Using these websites, you can decipher a message which was earlier enciphered by you or someone else. These website ask you for the keyword and cipher text. After that, they construct the key matrix and finally decrypt the cipher that you have specified. All these websites are very simple to use. Also, on some of these websites, you will find options to define some rules in order to decode the puzzle. And not only decoding Playfair cipher, but these websites can also be useful in encoding a plain text using the Playfair method.
Playfair cipher is a very powerful and one of the oldest cryptography techniques. It was used heavily till WWII and now it is generally used by treasure hunters or the people of the same sort. Playfair results in an impossibly decrypted message which no one can decode without a keyword. So, you can only decode the message if you have the keyword with you. Also, you can do that manually, but it will consume a lot of your time to do that. And that is why I have listed these websites. You just have to specify the cipher text and the keyword. After that, they will take care of the hard part and will yield you the result in just a fraction of a second.
5 Free Playfair Cipher Solver Websites to Decode Encrypted Message:
Playfair Cipher by GEOcaching Toolbox
Playfair cipher by GEOcaching Toolbox is a nice free Playfair cipher solver website you can use. To decipher a message, you have to give it the encrypted text and the keyword to use.

Playfair Cipher by Crypto Online
Playfair Cipher by Crypto Online is another free website to solve the messages which are enciphered by Playfair method. Just like the website above, you simply start by specifying the keyword and cipher text. After that, it will show you the decoded message along with the key matrix. And during the decryption process, you can opt for certain options. For example, you can instruct it to use “I” for “J”, ignore “Q”, ignore “X” like options.
Go to the homepage of the website and then enter the keyword to decrypt the message. Next, specify the cipher text to decrypt and then specify the decoding options. Finally, when you are all set, click on “Decrypt” button to see the final decoded message in plain text form. After it has given you the text, you can copy that to clipboard.
Playfair Cipher by Rumkin
Playfair Cipher by Rumkin is a simple online tool for you to easily encrypt, decrypt messages using Playfair algorithm. To decode an encoded message on this website is very simple. You just need to input the keyword or key phrase along with the decoded text. After that, it will build a key matrix for you and will show the final output. However, there are not so much options to define the explicit rules for deciphering the message. You can only opt to resolve “J” and “I” conflictions on this website. And apart from decoding message, you can also use this website to encipher a message using Playfair cipher technique.
The look and feel of this website is very simple. The tool is at the bottom left side and after finding it, specify the keyword in the “Alphabet key” box and then specify the corresponding ciphered text in the “Your Message” box. After that, make sure that method drop down set to “Decrypt”. Finally, after specifying all the parameters, you will get to see the decrypted message in a small pop up.
Playfair Cipher Tool
Playfair Cipher Tool is yet another free website for you to easily decrypt messages and encrypt them using the same method. The simple interface of the website makes it very easy to deal with the Playfair cipher text encryption and decryption process. It will just take the cipher text from you along with the keyword and will show you the output. However, here it doesn’t allow you to specify some external parameters to assist the decryption process. It uses a predefined approach to solve the Playfair cipher text for you.
Go to the homepage of the tool and then enter the target cipher in the “Message to decipher” box. Next, enter the keyword in the respective field and then hit the Submit button. It will show you the decoded text which was hidden in the cipher text that you specified. Apart from deciphering, if you want, you can create a Playfair cipher by using this website as well.
Playfair Calculator is the last free Playfair cipher solver in my list for you. This Playfair cipher solver on this website is quite an advanced one as it shows some additional details along with the message decryption result. Just like others, it also takes the keyword and cipher text from your end and then tells you what the actual message hidden in the encrypted text. And not only that, along with the result, you will see other parameters like frequency analysis of text, frequency of occurrence, etc. And apart from decoding Playfair cipher, you can also use this to encipher messages using the Playfair method.
Using Playfair Calculator is very simple especially when you want to decrypt a message. Access the homepage of the tool and then make sure you have the cipher text and keyword are ready. After reaching the homepage of the tool, simply specify these parameters and then click on “Analyze” button to see the decrypted text. And with the decrypted text, you will be able to see the other results like frequency analysis.
These are the best free Playfair cipher solver websites that I have found. All these websites can easily decipher a encoded message using the Playfair method. All you have to do is specify the cipher text along with the keyword. And then these websites will do the rest. In my opinion, I will recommend you to use Playfair Cipher by GEOcaching Toolbox, Playfair Cipher by Crypto Online, and Playfair Calculator. You can use others if you want some simple tools to do the same.
