SecureDolphin encrypts and decrypts E-mails sent in Yahoo and GMail. It is completely client side, i.e. no one has your keys, passwords or other sensitive data - only you do.
SecureDolphin creates two new buttons in your mailox - Encrypt and Decrypt. No need to install any extra software. SecureDolphin has everything, you need and works right in your mailbox. Keep using your usual web mail and enjoy the protection.
SecureDolphin is fundamentally more secure and convenient than other email encryption extensions. All other alternatives require you to find a way to exchange key or password or something else with your correspondent. SecureDolphin does the key exchange for you. The most difficult problem of email encryption is solved!
The key exchange is done using BitCoin and NameCoin protocols, which allows completely decentralized operation with no keys or passwords ever stored on any server or other, potentially vulnerable 3rd party. That is fundamentally superior to other known alternatives that require users to meet and exchange keys in person or rely on potentially untrustworthy 3rd parties to do so.
During the installation, the public key of SecureDolphin user is broadcasted in the NameCoin network. NameCoin provides publicly accessible and tamper-proof storage for small bits of information. SecureDolphin uses NameCoin to pair E-mail addresses with public keys used for encryption.
When encrypting emails, SecureDolphin looks up the receiver's public key by their E-mail address and uses it for encryption. The recipient has the corresponding private key on her or his computer. SecureDolphin uses that key to decrypt messages upon the click on "Decrypt" button that is planted in GMail and Yahoo during SecureDolphin installation.
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!
