Free secure attachment software for mac

i23 is a useful application to secure store your important data like passwords/serials/pins/tans. Password protected documents can only be opened on the same architecture (Intel/PPC). i23 uses a 320bit encryption and by quitting the application the clipboard is cleared.

KeePassX is a tool designed for those of you who have extremly high demands on secure personal data management. It has a light interface, is cross platform and published under the terms of the GNU General Public License.
KeePassX saves many different information e.g. user names, passwords, urls, attachemts and comments in one single database. For a better management user-defined titles and icons can be specified for each single entry.
Furthermore the entries are sorted in groups, which are customizable as well. The integrated search function allows to search in a single group or the complete database.
KeePassX offers a little utility for secure password generation. The password generator is very customizable, fast and easy to use. Especially someone who generates passwords frequently will appreciate this feature.
The complete database is always encrypted either with AES (alias Rijndael) or Twofish encryption algorithm using a 256 bit key. Therefore the saved information can be considered as quite safe. KeePassX uses a database format that is compatibel with KeePass Password Safe. This makes the use of that application even more favourable.
Originally KeePassX was called KeePass/L for Linux since it was a port of Windows password manager Keepass Password Safe.
After KeePass/L became a cross platform application the name was not appropriate anymore and therefore, on 22 March 2006 it has been changed.

Attachment Scanner Plugin is the tool for you is you forget to include an attachment on your emails.

It happens to me all the time. By the time I get done writing my email, I forget that I needed to attach something to it before hitting Send.

This Mail.app plugin helps avoid that problem. When you send a message, it checks if theres an attachment. If there isnt, and it looks like youve referred to an attachment in the body of your mail (by using a word like attach, attaching, attachment, etc), it gives you a warning.

Most of the time, you should never notice that this plugin is running, but in those cases when you do need it.

Save/Expand Attachments E will save message attachments to a folder you have previously selected.

The script can expand any files which Stuffit Expander can handle (your preference whether or not to do so), and can delete the original stuffed file if you wish.

Secure Delete Drop is an AppleScript droplet that securely and thoroughly deletes files that are droped onto it.
Drop some files onto the icon of Secure Delete Drop, and those files are overwritten three times with a meaningless byte pattern and then deleted.

There is no chance of retrieving the deleted files after Secure Delete Drop has finished its work.
