NAME
passwd.conf -- password encryption configuration file
SYNOPSIS
passwd.conf
DESCRIPTION
The /etc/passwd.conf file, consisting of ``stanzas'', describes the con-
figuration of the password cipher used to encrypt local or YP passwords.
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 speci-
fies 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

starting from NetBSD 6.0.
