Apache HTTP Server Version 2.2
htpasswd
is used to create and update the flat-files used to
store usernames and password for basic authentication of HTTP users. If
htpasswd
cannot access a file, such as not being able to write
to the output file or not being able to read the file in order to update it,
it returns an error status and makes no changes.
Resources available from the Apache HTTP server can be restricted to
just the users listed in the files created by htpasswd
. This
program can only manage usernames and passwords stored in a flat-file. It
can encrypt and display password information for use in other types of data
stores, though. To use a DBM database see dbmmanage
.
htpasswd
encrypts passwords using either a version of MD5
modified for Apache, or the system's crypt()
routine. Files
managed by htpasswd
may contain both types of passwords; some
user records may have MD5-encrypted passwords while others in the same file
may have passwords encrypted with crypt()
.
This manual page only lists the command line arguments. For details of
the directives necessary to configure user authentication in
httpd
see the Apache manual, which is part of the
Apache distribution or can be found at http://httpd.apache.org/.

crypt()
encryption for passwords. The default on all
platforms but Windows, Netware and TPF. Though possibly supported by
htpasswd
on all platforms, it is not supported by the
httpd
server on Windows, Netware and TPF.-s
-p
htpasswd
will support
creation on all platforms, the httpd
daemon will
only accept plain text passwords on Windows, Netware and TPF.-D

or rewritten and truncated if it does exist.username

-b
flag.htpasswd
returns a zero status ("true") if the username and
password have been successfully added or updated in the
passwdfile. htpasswd
returns 1
if it
encounters some problem accessing files, 2
if there was a
syntax problem with the command line, 3
if the password was
entered interactively and the verification entry didn't match,
4
if its operation was interrupted, 5
if a value
is too long (username, filename, password, or final computed record),
6
if the username contains illegal characters (see the
Restrictions section), and 7
if the file is not a valid password file.
htpasswd /usr/local/etc/apache/.htpasswd-users jsmith
Adds or modifies the password for user jsmith
. The user
is prompted for the password. If executed on a Windows system, the password
will be encrypted using the modified Apache MD5 algorithm; otherwise, the
system's crypt()
routine will be used. If the file does not
exist, htpasswd
will do nothing except return an error.
htpasswd -c /home/doe/public_html/.htpasswd jane
Creates a new file and stores a record in it for user jane
.
The user is prompted for the password. If the file exists and cannot be
read, or cannot be written, it is not altered and htpasswd
will display a message and return an error status.
htpasswd -mb /usr/web/.htpasswd-all jones Pwd4Steve
Encrypts the password from the command line (Pwd4Steve
)
using the MD5 algorithm, and stores it in the specified file.
Web password files such as those managed by htpasswd
should
not be within the Web server's URI space -- that is, they should
not be fetchable with a browser.
The use of the -b
option is discouraged, since when it is
used the unencrypted password appears on the command line.
On the Windows and MPE platforms, passwords encrypted with
htpasswd
are limited to no more than 255
characters in length. Longer passwords will be truncated to 255
characters.
The MD5 algorithm used by htpasswd
is specific to the Apache
software; passwords encrypted using it will not be usable with other Web
servers.
Usernames are limited to 255
bytes and may not include the
character :
