PW_GETCONF(3)						   BSD Library Functions Manual 					     PW_GETCONF(3)

pw_getconf, pw_getpwconf -- password encryption configuration access function LIBRARY
System Utilities Library (libutil, -lutil) SYNOPSIS
#include <util.h> void pw_getconf(char *data, size_t len, const char *key, const char *option); void pw_getpwconf(char *data, size_t len, const struct passwd *pwd, const char *option); DESCRIPTION
The pw_getconf() function reads /etc/passwd.conf and retrieves the value of the option specified by option from the section given by key. If no suitable entry is found for the key an empty string will be returned in data. To retrieve default values the key default can be used. In this case, if /etc/passwd.conf does not exist or does not contain a default sec- tion, the built-in defaults will be returned. They are as follows: option data ypcipher old localcipher old An empty string is returned for all errors. pw_getpwconf() returns the value for the option specified for the particular user specified in pwd. If that option is not found, then it tries to find the option in the primary group of that user, and if that fails, then it returns the default entry. FILES
/etc/passwd.conf ERRORS
pw_getconf() and pw_getpwconf() will fail if: [ENOENT] There is no option named option in the specified key. [ENOTDIR] There is no key in /etc/passwd.conf named key. SEE ALSO
passwd(5), passwd.conf(5) HISTORY
The pw_getconf() function first appeared in NetBSD 1.6. BSD

passwd.conf -- password encryption configuration file SYNOPSIS
passwd.conf DESCRIPTION
The /etc/passwd.conf file, consisting of ``stanzas'', describes the configuration of the password cipher used to encrypt local or YP pass- words. There are default, user and group specific stanzas. If no user or group stanza to a specific option is available, the default stanza is used. To differentiate between user and group stanzas, groups are prefixed with a single colon (':'). Some fields and their possible values that can appear in this file are: localcipher The cipher to use for local passwords. Possible values are: ``old'', ``newsalt,<rounds>'', ``md5'', ``sha1,<rounds>'', and ``blowfish,<rounds>''. For ``newsalt'' the value of rounds is a 24-bit integer with a minimum of 7250 rounds. For ``sha1'' the value of rounds is a 32-bit integer, 0 means use the default of 24680. For ``blowfish'' the value can be between 4 and 31. It specifies the base 2 logarithm of the number of rounds. If not specified, the default value is ``old''. ypcipher The cipher to use for YP passwords. The possible values are the same as for localcipher. If not specified, the default value is ``old''. To retrieve information from this file use pw_getconf(3). FILES
/etc/passwd.conf EXAMPLES
Use SHA1 as the local cipher and old-style DES as the YP cipher. Use blowfish with 2^5 rounds for root: default: localcipher = sha1 ypcipher = old root: localcipher = blowfish,5 SEE ALSO
passwd(1), pwhash(1), pw_getconf(3), passwd(5) HISTORY
The passwd.conf configuration file first appeared in NetBSD 1.6. The default value of localcipher was set to ``sha1'' in /etc/passwd.conf starting from NetBSD 6.0. BSD
