SYSTEMKEYCHAIN(8) BSD System Manager's Manual SYSTEMKEYCHAIN(8)NAMEsystemkeychain -- creates system keychains and allows keychains to unlock keychainsSYNOPSISsystemkeychain [-fv] [-k filename] [-C] [password] systemkeychain [-fvc] [-k filename] [-s] [file ...] systemkeychain [-v] [-k filename] [-t]DESCRIPTIONThe systemkeychain can be used to create a system keychain, make it possible for a keychain to unlock another keychain, or test unlocking a keychain. The options are as follows: -C Create a keychain and establish it in the system as the primary system keychain whose unlocking is automatically handled by the sys- tem. The new keychain is empty. If the optional password argument is given, the keychain can be also be unlocked with that; other- wise, the keychain has no password and can only be unlocked by the system. The optional password option is generally used for test- ing purposes, and using it is not recommended. -s Extract the master secret from source keychain(s) and install them in a destination keychain to allow unlocking. -t Test unlocking the system keychain. -k systemKeychain Use a keychain other than the default as the destination system keychain. -c Create the target keychain if necessary. -f Force creation of a system keychain or overwriting of an existing key for keychain unlocking keychain operations. -v Turn on verbose mode. By default, systemkeychain works with the keychain file stored at /Library/Keychains/System.keychain . Use of the -k option can specify a different target file. Use of the -s option allows keychains to be setup to unlock other keychains. Chains of keychain unlocks can be setup in this manner to make a series of keychains unlock while only needing to manually unlock the first one. This functionality can be verified with the -t (test unlock) option.FILES/Library/Keychains/System.keychainDIAGNOSTICSThe systemkeychain utility exits 0 on success, and >0 if an error occurs.HISTORYThe systemkeychain command appeared in Mac OS 10.2.0 .BSDMarch 14, 2006 BSD
