21config FEATURE_SHADOWPASSWDS
22    bool "Support for shadow passwords"
23    default y
24    help
25      Build support for shadow password in /etc/shadow. This file is only
26      readable by root and thus the encrypted passwords are no longer
27      publicly readable.
28
29config USE_BB_PWD_GRP
30    bool "Use internal password and group functions rather than system functions"
31    default y
32    help
33      If you leave this disabled, busybox will use the system's password
34      and group functions. And if you are using the GNU C library
35      (glibc), you will then need to install the /etc/nsswitch.conf
36      configuration file and the required /lib/libnss_* libraries in
37      order for the password and group functions to work. This generally
38      makes your embedded system quite a bit larger.
39
40      Enabling this option will cause busybox to directly access the
41      system's /etc/password, /etc/group files (and your system will be
42      smaller, and I will get fewer emails asking about how glibc NSS
43      works). When this option is enabled, you will not be able to use
44      PAM to access remote LDAP password servers and whatnot. And if you
45      want hostname resolution to work with glibc, you still need the
46      /lib/libnss_* libraries.
47
48      If you need to use glibc's nsswitch.conf mechanism
49      (e.g. if user/group database is NOT stored in /etc/passwd etc),
50      you must NOT use this option.
51
52      If you enable this option, it will add about 1.5k.
53
54config USE_BB_SHADOW
55    bool "Use internal shadow password functions"
56    default y
57    depends on USE_BB_PWD_GRP && FEATURE_SHADOWPASSWDS
58    help
59      If you leave this disabled, busybox will use the system's shadow
60      password handling functions. And if you are using the GNU C library
61      (glibc), you will then need to install the /etc/nsswitch.conf
62      configuration file and the required /lib/libnss_* libraries in
63      order for the shadow password functions to work. This generally
64      makes your embedded system quite a bit larger.
65
66      Enabling this option will cause busybox to directly access the
67      system's /etc/shadow file when handling shadow passwords. This
68      makes your system smaller (and I will get fewer emails asking about
69      how glibc NSS works). When this option is enabled, you will not be
70      able to use PAM to access shadow passwords from remote LDAP
71      password servers and whatnot.
72
73config USE_BB_CRYPT
74    bool "Use internal crypt functions"
75    default y
76    help
77      Busybox has internal DES and MD5 crypt functions.
78      They produce results which are identical to corresponding
79      standard C library functions.
80
81      If you leave this disabled, busybox will use the system's
82      crypt functions. Most C libraries use large (~70k)
83      static buffers there, and also combine them with more general
84      DES encryption/decryption.
85
86      For busybox, having large static buffers is undesirable,
87      especially on NOMMU machines. Busybox also doesn't need
88      DES encryption/decryption and can do with smaller code.
89
90      If you enable this option, it will add about 4.8k of code
91      if you are building dynamically linked executable.
92      In static build, it makes code _smaller_ by about 1.2k,
93      and likely many kilobytes less of bss.

95config USE_BB_CRYPT_SHA
96    bool "Enable SHA256/512 crypt functions"
97    default y
98    depends on USE_BB_CRYPT
99    help
100      Enable this if you have passwords starting with "$5$" or "$6$"
101      in your /etc/passwd or /etc/shadow files. These passwords
102      are hashed using SHA256 and SHA512 algorithms. Support for them
103      was added to glibc in 2008.
104      With this option off, login will fail password check for any
105      user which has password encrypted with these algorithms.

124    help
125      Enable sanity check on user and group names in adduser and addgroup.
126      To avoid problems, the user or group name should consist only of
127      letters, digits, underscores, periods, at signs and dashes,
128      and not start with a dash (as defined by IEEE Std 1003.1-2001).
