|

If you leave this disabled, busybox will use the system's password
|
|
and group functions. And if you are using the GNU C library
|
|
(glibc), you will then need to install the /etc/nsswitch.conf
|
|
configuration file and the required /lib/libnss_* libraries in
|
|
order for the password and group functions to work. This generally
|
|
makes your embedded system quite a bit larger.
|
|
|
|
Enabling this option will cause busybox to directly access the
|
|
system's /etc/password, /etc/group files (and your system will be
|
|
smaller, and I will get fewer emails asking about how glibc NSS
|
|
works). When this option is enabled, you will not be able to use
|
|
PAM to access remote LDAP password servers and whatnot. And if you
|
|
want hostname resolution to work with glibc, you still need the
|
|
/lib/libnss_* libraries.
|
|
|
|
If you need to use glibc's nsswitch.conf mechanism
|
|
(e.g. if user/group database is NOT stored in /etc/passwd etc),
|
|
you must NOT use this option.
|
|
|
|
If you enable this option, it will add about 1.5k.

config BUSYBOX_CONFIG_USE_BB_CRYPT
|
|
bool "Use internal crypt functions"
|
|
default n
|
|
help
|
|
Busybox has internal DES and MD5 crypt functions.
|
|
They produce results which are identical to corresponding
|
|
standard C library functions.
|
|
|
|
If you leave this disabled, busybox will use the system's
|
|
crypt functions. Most C libraries use large (~70k)
|
|
static buffers there, and also combine them with more general
|
|
DES encryption/decryption.
|
|
|
|
For busybox, having large static buffers is undesirable,
|
|
especially on NOMMU machines. Busybox also doesn't need
|
|
DES encryption/decryption and can do with smaller code.
|
|
|
|
If you enable this option, it will add about 4.8k of code
|
|
if you are building dynamically linked executable.
|
|
In static build, it makes code _smaller_ by about 1.2k,
|
|
and likely many kilobytes less of bss.

Enable this if you have passwords starting with "$5$" or "$6$"

|
|
are hashed using SHA256 and SHA512 algorithms. Support for them
|
|
was added to glibc in 2008.

user which has password encrypted with these algorithms.
