Tiny Deathstars of Foulness

Previously, I covered how to Programmatically Obtain Recent Wi-Fi Networks On A Mac. But, here I’m gonna’ go a step further and look at how to extract the password for a network as well. The two are stored in different locations. The recent networks are in the /Library/Preferences/SystemConfiguration/com.apple.airport.preferences defaults domain. If you pull one of those, then you can use the security command to extract the password itself. security find-generic-password -ga "Krypted Home" The output is as follows, showing everything that is tracked about this network in the keychain. keychain: "/Library/Keychains/System.keychain" class: "genp" attributes: 0x00000007 <blob>="Krypted Home" 0x00000008 <blob>=<NULL> "acct"<blob>="Krypted Home" "cdat"<timedate>=0x32303135313230373135313731375A00 "20151207151717Z\000" "crtr"<uint32>=<NULL> "cusi"<sint32>=<NULL> "desc"<blob>="AirPort network password" "gena"<blob>=<NULL> "icmt"<blob>=<NULL> "invi"<sint32>=<NULL> "mdat"<timedate>=0x32303135313230373135313731375A00 "20151207151717Z\000" "nega"<sint32>=<NULL> "prot"<blob>=<NULL> "scrp"<sint32>=<NULL> "svce"<blob>="AirPort" "type"<uint32>=<NULL> password: "test" You can constrain the output with awk and grep so that you’d only see the password as the output of the command. Then, you can feed it back into other objects, like a new .mobileconfig.
