password-protection

问题 I am trying to password protect a subdomain and all of it\'s subdirectories and files, but my knowledge on the matter is very limited, how can I go about doing that? 回答1: It's a simple two step process In your .htaccess put AuthType Basic AuthName "restricted area" AuthUserFile /path/to/the/directory/you/are/protecting/.htpasswd require valid-user use http://www.htaccesstools.com/htpasswd-generator/ or command line to generate password and put it in the .htpasswd Note 1: If you are using

问题 I\'m just learning to use SQLite and I was curious if such is possible: Encryption of the database file? Password protect opening of the database? PS.

Now Blowfish is also available in PHP via mcrypt , but how does that help with storing passwords? Blowfish is a general purpose cipher, it works two ways. If it could be encrypted, it can be decrypted.
