Custom Cryptogram

The purpose of this utility is to allow you to encrypt a message you want to send as a puzzle to one of your brainy friends. Enter your message below, and click the Encrypt button. The message will be put into a letter substitution cipher, which you can copy from the screen and paste into an email.

Naturally, you could do this all yourself; however, if you prefer challenges of a more interesting sort than manually generating a cipher key and then translating your message by hand, this is the tool for you.
