Is there a Command Prompt Application or app for GPG with email?

[kevdog]

I'm looking for two applications and I'm not sure if they are available #1 - An app to run a command prompt on the phone itself away from a computer. I'm aware of adb, but this requires interfacing the device through the usb port. Is there a stand alone application? #2 - I'm a big fan of GnuPG however am not aware of a program to offer this functionality on the android system. I usually use FireGPG with Mozilla, however the built in android browser is no Mozilla. Any suggestions? Thank You
