Firmware Update And Verification With Digital Signed Certificate

VOSS software images are cryptographic signed. Code signing is the process of digitally signing executables and scripts to confirm the software author and guarantee that the code has not been altered or corrupted since it was signed. This process employs the use of a cryptographic hash to validate authenticity and integrity.

The show software command displays information about the software image:
