Secured eMail Reader software was designed with the recipient in mind, making the otherwise unsecure means of communication, secure for all users.
Implementing a security solution is important; however, it is equally important that the receiver doesn?t feel burdened by the process. Any Windows user can receive a secured email. They simply download a free Reader (similar to downloading the Adobe PDF Reader). With the Reader the recipient can open the secured email.
If the receiving party uses any of the supported email clients, they can reply secured for free as many times as they like. This means that you can have a secure communication with receivers without forcing them to buy any software or hardware. All secured emails sent also have a very easy to understand explanation regarding the secured email, including how to download the Free Reader and open the email.
Ease of use
Unlike PKI solutions that rely on you having a certificate before even you can even receive an encrypted email, Secured eMail lets the sender choose a one-time shared secret that works like a password for you as a recipient. It is called a "one-time shared secret" because it is only used once. After you have opened the first secured email for that contact, it will never be required again - Secured eMail will handle it for you. This is also where the power lies.
Technology
Secured eMail relies upon System SKG (Synchronous Key Generator) to handle the encryption keys that it uses. It is fully automated and doesnt require any interaction with the user. This is a completely transparent system and thereby not enforcing a new working routine for the user. All they do is click the "Send secured" button instead of "Send", and the email is secured and on its way to the recipient.
Main features:
- Send & Receive
With Secured eMail Reader installed, you can read secured emails that you receive through webmail, or any email client.
If you are using any of the fully supported email clients, Secured eMail will integrate itself with that and you will be able to also Send 10 FREE secured emails.

If you are using any of the fully supported email clients, Secured eMail will integrate itself with that and you will be able to reply secured for FREE, without purchasing a license!

TextCrypt is a small and simple application that you can use for encrypting your emails. TextCrypt is a small and simple application that you can use for encrypting your emails.
Write your text in TextCrypt. Create the encrypted file and attach it in your mail. Pretty simple.
TextCrypt uses an Artificial Neural Network (ANN) for encryption/decryption.
The ANN uses the backpropagation algorithm for learning the text entered in the text box.
When the ANN has learned the complete text, the weights (brain cell values)
are written to a file. A key contains the input to the ANN, the number of hidden
neurons to be used, and more... in other words: Nobody without the key read your emails!
If you encrypt the same text several times, youll never get the same encrypted output.

Comodo SecureEmail automatically secures your email messages so that the message and its attachments cannot be intercepted, read or altered on its way through the Internet.
The software encrypts and digitally signs the outgoing messages from the sender. Encrypting the message means that it can be deciphered and read only by the owner of the corresponding private key i.e. the intended recipient so that the confidential data from the sender cannot be stolen or modified on its way through the Internet. Digitally signing a message means that it proves to your recipient that the message came from you. In combination, these two assure the recipient that the received message and its attachments were not adulterated by anyone along the way.
The software features a built-in wizard to easily download and setup a Comodo email certificate for encryption and digital signing. If your contact (recipient) is a CSE user, you can easily import his/her public key for encrypting your message to him/her. The message can be decrypted only using his/her private key. If your contact is not a CSE user, single use or onetime session certificates will be used. The encrypted email is then sent to your recipient. The recipient can decrypt and read the email by using the our easy-to-use Web reader service. This enables to encrypt the mail for anyone at anytime.
Users will benefit from the security of their email while the application handles difficult or hard to remember processes such as public-key exchange.
The software features full compatibility with Outlook, Thunderbird, Incredimail and many other POP, SMTP and IMAP based mail clients.
Network administrators looking to implement total client-to-client email security may consider Comodo SecureEmail as a complement to gateway encryption applications which overlook the vulnerability of emails being exchanged within the network.
Comodo SecureEmail like all Comodo desktop software, is free of charge for home and business users.
