how do email attachments work

iOpus Secure Email Attachments 1.0
Create a 448 bit encrypted compressed attachment with your sensitive documents. more>> Lets face it, in the real world many people simply arent willing to buy and install a specific encryption package just to be able to read a couple of files you send them. With iOpus Secure Email Attachments (SEA) they dont have to, because you can send them self-decrypting archives that "unpack" themselves. The recipient just double clicks on the file and enters the password at the prompt displayed. The original files are then decrypted, extracted and written to your disk automatically.
In just a few moments, you can create an encrypted, compressed (ZIP) attachment with your sensitive documents. Ideal for sending information by email or making secure backups. Thanks to compression, iOpus SEA packages are up to 95 % smaller than the original files, saving time and money for e-mail transmission. The recipient requires no special software, because iOpus SEA packages decode themselves after the password is entered.
If desired, your company logo, a custom message, and a link to your home page can be displayed: the perfect combination of branding and security. In addition, your disclaimer may be displayed: your client has to accept it before decrypting the iOpus SEA package.?
iOpus SEA uses the Blowfish encryption algorithm with a key length of up to 448 bits. Blowfish encryption is so strong that it has never been cracked yet. In fact, most experts agree that it cannot be cracked with current computer technology and that includes supercomputers!
Your time is not worth waiting for your computer to do what you want him to do. iOpus SEA is very fast. Encrypting or decrypting a file hardly takes any longer than copying it.
iOpus SEA protects your data not only on its way across the internet, but also on the recipients PC.

System requirements:
- Thunderbird: 2.0 ? 2.0.0.*
Enhancements:
- improvement: Added capability to use AttachmentExtractor on individual attachments in the attachment area in preview pane and message windows. Individual extracting doesnt delete or mark the message read afterwards but otherwise follows the same settings.
- improvement: AEs toolbar button is automatically added the first time you install AE if youve not already got it there. This will only happen once and if you remove it then it wont come back.
- improvement: The progress dialog now has progress bars as well as filenames and subjects. You can turn off the filenames and subject display in the settings dialog if you wish.
- improvement: Extraction requests can now be queued, rather than creating a new process. At the moment this isnt enable by default but can be by setting the preference attachmentextractor.queuerequests to true
- improvement: Invalid filename patterns, where the #count# token is missing, are fixed automatically in the settings dialog so the user cant accidentally break AE.
- bug fix: fixed bug in clear MRU code which always cleared off the last MRU item either on restart or settings change.
- bug fix: not having a default TB download folder specified doesnt now cause problems.
- bug fix: AE will now fail silently if a RSS feed message or an external attachment (a previously detached attachment) is attempted.
