The Playfair Cipher tool is a Chrome Packaged App for quickly encrypting and decrypting plain text with the Playfair Cipher. The Playfair Cipher is a simple pencil-and-paper cipher which doesn't suffer from some of the common weaknesses with simple substitution ciphers. However, it's not resistent to all forms of cryptanalysis.
This application sends no information over the network except the two preference checkbox are stored in your Google profile to be restored each time you start the tool. Neither keyphrases, plaintext, nor ciphertext are stored to disk or transmitted over the network.
THIS IS NOT A SECURE METHOD OF ENCRYPTION. This is for hobbyist or educational use only.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
