.htaccess密码保护不使用加密密码

I want to make my admin folder protected with htaccess file.Here is my htaccess file

AuthType Basic 
AuthName "Title for Protected Site"
AuthUserFile C:/WAMP/www/mysite/admin/.htpasswd
Require valid-user

I made htpasswd file and had password encrypted. When i try to access the folder it doesn't accept my password and opens another login, but when i set password to be admin, without encryption, it works. Does anybody have idea why this is happening? And if it is important, here is my apache error log

AH01617: user admin1: authentication failure for "/mysite/admin/": Password Mismatch
