NAME
mkpasswd - generate hashed password table SYNOPSIS
mkpasswd [ -p ] passwdfile DESCRIPTION
Mkpasswd is used to generated the hashed password database used by the password library routines (see getpwent(3)). The file passwdfile must be in password file format (see passwd(5)). Mkpasswd generates database files named ``passwdfile.pag'' and ``passwdfile.dir'' (see ndbm(3)). Data subsequently taken from the database files differ from passwdfile in one respect. Rather than storing the encrypted password in the database, mkpasswd stores the offset of the encrypted password in passwdfile. Mkpasswd exits zero on success, non-zero on failure. The -p option causes mkpasswd to create ``passwdfile.orig'', a password file in the standard Version 7 format. SEE ALSO

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 is based 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 -l flag defines the length of the password. The default is 9. The following example creates 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 at least 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 watching passwords being entered. This can also make it easier for a password-guessing program. 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 5 uppercase characters. mkpasswd -l 15 -d 3 -C 5 SEE ALSO
