No cryptographic merit This application doesn't protect your data at all. It doesn't use an Initialization Vector, fails to use a proper encryption method (Runs in ECB - i.e. Repeats blocks), and uses 3DES which is a horribly slow cipher when compared to more modern ones like AES. This might be a fun toy, but if you need to really secure data, you should probably look into something else.
I have evaluated dozens of cryptography programs and this is my choice for the Android. It is small, fast, and perfect for short private SMS.
Strengthened this app's paste-from-Clipboard-to-Textbox function. Note: Owners of older Samsung Galaxy smartphones may be plagued by an insidious Samsung clipboard copy&paste bug that causes a device reboot. This fatal error is not the fault of this app!
