Secure E-Mail

Return to Introduction  Previous  Next

The Secure e-mail module allows for the creation of encrypted files which can be sent as e-mail attachments. You can also create self extracting encrypted files which don't require Cypherix for decryption. This allows for a totally secure communication system that makes use of existing e-mail clients (e.g. Outlook Express) on a public network.


The password has to be communicated between two parties over an alternate channel, for example, either through a telephonic conversation or during pre-arranged meetings or a reference to a common shared resource (e.g. a book or a magazine). You can also use the "riddle" field to send across a password hint to the recipient.


You can send secure e-mail files in a number of ways.


1.   Standalone files (self executables, .exe ).

These can be decrypted and viewed at the recipient's end on any Windows machine without any software. The recipient does of course needs to know the password/phrase.


2.   .SIT Files

Given that most virus scanners delete most executable files almost automatically, Cypherix LE also allows for the creation of .sit encrypted files. These can be e-mailed to the recipient, We recommend that you use this method.


The recipient needs to download Cypherix LE and then decrypt them.


Alternately The recipient needs a free utility DecypherIT. Once installed, this free "reader" allows the recipient to decrypt encrypted files (.SIT extension) very simply. You can request your associate to download this free reader from


3.   Sending Cypherix Vaults

You can always send entire Cypherix Vaults to recipients. They can use Additional volumes feature of Cypherix LE to use them, as you would if they know the password.
