Link Encoder

Link Encoder is a tiny and portable app that can quickly encode your email address, display name and subject, in addition to links and any type of text. This way, you can encrypt information when sending messages over insecure servers and prevent any outsiders from getting hold of your secrets.

Portable tool with a simple GUI

Since there's no setup kit, you can copy the downloaded .exe file to a custom folder on the local disk or to a USB flash drive, in order to carry it with you at all times and secure emails sent from a public hotspot. It doesn't create files on the HDD without your permission, need DLLs to run, or change the Windows registry configuration.
Concerning the interface, Link Encoder sticks to a normal window with a plain appearance and neatly structured layout, where you can easily get an overview, since all options are visible.

Encode emails, links and any text

All you have to do is enter your email address, display name and subject, one or more links (one per line), along with any type of text. It's possible to take into account any of these three for the operation.
The encrypted code is immediately generated and shown in the bottom part of the window. You can toggle between HTML and source code viewing mode, copy the code to the Clipboard, as well as click the hyperlinked entry in the HTML format to launch your default email client and swiftly send the encrypted message.
