Extract the subject of the signing certificate of a .mobileprovision file

dev-cert.sh

#!/bin/sh

# Extract the subject of the signing certificate of a .mobileprovision file

if [ -z "$1" ]
then
	echo "Usage: $0 [mobileprovision-file]"
	exit 1
fi

end=`grep -n --binary-files=text '</plist>' "$1"|cut -d: -f-1`

sed -n "2,${end}p" "$1"|xpath '//data' 2>/dev/null|sed -e '1d' -e '$d'|base64 -D| \
	openssl x509 -subject -inform der|head -n 1

security cms -D -i path_to_mobileprovision > tmp.plist && /usr/libexec/PlistBuddy -c 'Print :Entitlements:application-identifier' tmp.plist

Ok, i got "notAfter=Jul 9 06:53:40 2017 GMT".
Is that looks like a normal output ?! what is it ?

You can extract the plist cleanly using openssl nowadays:

openssl smime -inform der -verify -noverify -in file.mobileprovision

Can be useful if you are trying to work with the file and data on Windows for example where all the others things are a lot harder to use or don't exist.
