Digitally Signed Executables AKA Code Signing

Hi All,

I've been playing with Windows PowerShell at work and have gained an appreciation for how Microsoft has implemented it. Aside from being a cool environment that actually makes Windows palatable, PowerShell scripts are by default only allowed to be run when they have a trusted digital signature. I think code signing is a great idea and would love to know where this has been / can be implemented in Linux.

Linux and other FOSS have always been my #1 interest. I bring this and all it's taught me around everywhere, even to my day job. I work by day as a cyber security analyst for a mostly Windows Desktop and Windwos Server shop. Often, I get very frustrated with my Windows-Centric coworkers. It is tedious but I'm steadily introducing them all to Linux and FOSS.

The linux kernel has an option called CONFIG_MODULE_SIG_FORCE which ensures that unsigned modules cannot be inserted into a running kernel (think rootkits). There is also a lot work in progress regarding secure boot in terms of using a TPM, signed grub bootloader and signed kernels.
