From the developer:
SecureSend is a program which allows you to send confidential information online. The program securely and irreversibly encrypts your information with many complex algorithms, all tied to a password of your choice. This means that the app will take your confidential data, encrypt it with your secret password, and output a bunch of garbage text which is absolutely useless to anyone - except for the person you choose to send the information to.
