Re: signature clause in mac_permisions

[Joshua Brindle <method@manicmethod.com>]

If you want to go straight from cert to hex encoding without having to 
sign an app (i.e., you are generating certs and policies at the same 
time) you can use this:

$openssl x509 -inform PEM -in <certname>.x509.pem -outform DER

Script to encode:

#!/usr/bin/env python

import sys
content = sys.stdin.read().strip()
foo = content.encode("hex")
sys.stdout.write(foo)


The script to encode has to be very careful about padding or null 
terminating, hence why I couldn't just use some random command line tool.
