36 .Nd password encryption configuration file
44 describes the configuration of the password cipher used
45 to encrypt local or YP passwords.
47 There are default, user and group specific stanzas.
49 stanza to a specific option is available, the default stanza
52 To differentiate between user and group stanzas, groups are prefixed
56 Some fields and their possible values that can appear in this file are:
57 .Bl -tag -width localcipher
59 The cipher to use for local passwords.
62 .Dq newsalt,\*[Lt]rounds\*[Gt] ,
64 .Dq sha1,\*[Lt]rounds\*[Gt] ,
66 .Dq blowfish,\*[Lt]rounds\*[Gt] .
69 the value of rounds is a 24-bit integer with a minimum of 7250 rounds.
72 the value of rounds is a 32-bit integer, 0 means use the default
76 the value can be between 4 and 31.
77 It specifies the base 2 logarithm of the number of rounds.
79 The cipher to use for YP passwords.
80 The possible values are the same as for localcipher.
83 To retrieve information from this file use
86 .Bl -tag -width /etc/passwd.conf -compact
87 .It Pa /etc/passwd.conf
90 Use MD5 as the local cipher and old-style DES as the YP cipher.
91 Use blowfish with 2^5 rounds for root:
98 localcipher = blowfish,5
