The mkpasswd generates indexes over certain security files. These indexes are used by the getpwnam, getpwuid, getuserattr, and putuserattr library subroutines. This approach significantly enhances performance for large user base systems.

OPTIONS¶-S, -salt=STRING Use the STRING as salt. If it begins with $ then it will be passed straight to crypt(3) without any checks.-R, -rounds=NUMBER.

I just looked at the PKGBUILD and Makefile and saw that it only installs 'mkpasswd'. My apologies for wrongly filing it as outdated. I had the impression that something might be fishy with the package when I.

Name

mkpasswd - generate new password, optionally apply it to a user

Synopsis

mkpasswd [ args ] [ user ]

Introduction

mkpasswd generates passwords and can apply them automatically to users. mkpasswd isbased on the code from Chapter 23 of the O'Reilly book 'Exploring Expect'.

Usage

With no arguments, mkpasswd returns a new password.

mkpasswd

With a user name, mkpasswd assigns a new password to the user.

mkpasswd don

The passwords are randomly generated according to the flags below.

Flags

The

Mkpasswd Package

-l

Mkpasswd Centos

flag defines the length of the password. The default is 9. The following examplecreates a 20 character password.

mkpasswd -l 20

The -d flag defines the minimum number of digits that must be in the password. The default is 2. The following example creates a password with atleast 3 digits.

mkpasswd -d 3

The -c flag defines the minimum number of lowercase alphabetic characters that must be in the password. The default is 2.

The -C flag defines the minimum number of uppercase alphabetic characters that must be in the password. The default is 2.

The -s flag defines the minimum number of special characters that must be in the password. The default is 1.

The -p flag names a program to set the password. By default, /etc/yppasswd is used if present, otherwise /bin/passwd is used.

The -2 flag causes characters to be chosen so that they alternate between right and left hands (qwerty-style), making it harder for anyone watchingpasswords being entered. This can also make it easier for a password-guessing program.

Mkpasswd

The -v flag causes the password-setting interaction to be visible. By default, it is suppressed.

Example

The following example creates a 15-character password that contains at least 3 digits and 5uppercase characters.

mkpasswd -l 15 -d 3 -C 5

mkpasswd is in the public domain. NIST and I would appreciate credit if this program or parts of it are used.
