It happened several times that I was looking for htpasswd.exe which is distributed with the apache web server, but had it not handy. The apache foundation unfortunately does not distribute this exec separately, and installing / uninstalling the server just to get the password making program is a bit tedious. So here it is:
htpasswd.exe
.
Note that the Windows executable cannot encode the password using the CRYPT method (although it says so in the help screen). If you need to make passwords for a system expecting CRYPT, you may use the service at http://www.askapache.com/online-tools/htpasswd-generator/
