A self decrypting message can be created where you require a message to be able to be decrypted (using the Pass Phrase) without the recipient having QuickCrypto on their system.

 

They are very useful in this regard BUT many email systems and most personal and corporate firewalls will isolate these types of messages as being potentially harmful.

 

They are not of course, but to enable the self decrypting function, a small program is attached to the encrypted message, which means the email message becomes an “.exe” type file, which is an application (a software program).

 

".exe" files received by email are routinely quarantined or automatically deleted in case they contain a virus or other unexpected software.

 

So self decrypting messages are useful, but they have their limitations in the real world …

 

 

QuickCrypto will provide an option to "Zip" (compress) the self-decrypting message application. This sometimes allows the email recipients system to allow the message through. This usually works for personal email systems, but corporate systems will still often quarantine or delete these type of attachments.

 

 

To create a self decrypting text message, enter your text in the Text Window, click the “Self DeCryptor” button.

 

If the text has already been encrypted a screen will be presented requesting you give a name for the message and give a folder location for the compiled self decrypting message to be saved in.

 

If the text is not encrypted you will be asked for a Pass Phrase and the text will be encrypted prior to the request asking for a name for the message.

 

QuickCrypto will then ask if you want to send this message by email. Click "Yes" if this is required and the self-decrypting message will be attached to an email ready to send.

 

Note that QuickCrypto will also ask if you wish to "Zip" (compress) the message first - this is recommended. This message file can then be sent to the recipient, but please see the possible limitations of this approach listed above.

 

 

To decrypt the message simply ‘double-click’ on the message file (from say within Windows Explorer or as attached to an email) and it will automatically decrypt (once the correct Pass Phrase is entered).
