Signing FIT container with private key in an image
|
||||
--------------------------------------------------
|
||||
|
||||
You can sign FIT container with private key in your image.
|
||||
For example::
|
||||
|
||||
$ binman sign -i image.bin -k privatekey -a sha256,rsa4096 fit
|
||||
|
||||
binman will extract FIT container, sign and replace it immediately.
|
||||
|
||||
If you want to sign and replace FIT container in place::
|
||||
|
||||
$ binman sign -i image.bin -k privatekey -a sha256,rsa4096 -f fit.fit fit
|
||||
|
||||
which will sign FIT container with private key and replace it immediately
|
||||
inside your image.
