<IfModule mod_authn_file.c>
AuthType Basic
AuthName "Authorization Required"
AuthUserFile <passwordfile which is create by htpasswd cmd>
Require valid-user
</IfModule>
windows: apache/bin/htpasswd.exe
Linux: htpasswd
Usage:
htpasswd [-cmdpsD] passwordfile username
htpasswd -b[cmdpsD] passwordfile username password
htpasswd -n[mdps] username
htpasswd -nb[mdps] username password
-c Create a new file.
-n Don’t update file; display results on stdout.
-m Force MD5 encryption of the password (default).
-d Force CRYPT encryption of the password.
-p Do not encrypt the password (plaintext).
-s Force SHA encryption of the password.
-b Use the password from the command line rather than prompting for it.
-D Delete the specified user.
On other systems than Windows, NetWare and TPF the ‘-p’ flag will probably not work.
The SHA algorithm does not use a salt and is less secure than the MD5 algorithm.
