Mail1Click

Mail1Click is a reliable and easy to use email client with advanced encryption methods, designed to help you protect the information you send and receive against being read or used by third-parties.
The application enables you to create an account, and requires that you use a 10-digit password containing upper and lower case letters, numbers and special characters, in order to make sure that it is as strong as possible against malicious attacks.
When sending a email, all you have to do is type in your message, optionally add hyperlinks or attach various files, and send it. Mail1Click takes care of the rest.
The program adds an electronic signature to all your emails and attachments, and automatically generates the encoded message, thus preventing anyone from reading your correspondence, in case it is intercepted.
The sent email is encoded with a 4096 bit RSA key, using a private and a public key. Your private key functions as an electronic signature for the messages you send, but also unlocks the emails you receive in your Inbox. Similarly, the public key encrypts the messages other people send you and allows the intended recipients to decipher the emails you send.
Mail1Click makes use of three distinct encryption algorithms: RSA, AES and TLS. RSA is a strong encoder designed to protect web traffic, ensure email privacy and secure online transactions. AES is particularly appealing thanks to its increased security levels and calculation speed. TLS aims at protecting the privacy of applications that communicate over the Internet. Combined, these three make it virtually impossible to decrypt or access your messages.
While Mail1Click may lack the complex functions found in regular email clients, it does provide you with strong encryption features, making it a great tool that you can resort to when sending sensitive information, without running the risk of having your data stolen or wrongly used.
