hello

please i need help with the encryption configuration ,jst downloaded blowfish encryption files but i don’t knw where to put them to make them functional with CI encryption class

furthermore i want to know if i have to alter my wamp configuration to make them functional with codeigniter

You will need the mcrypt extension, with also requires libmcrypt, libmcrypt-devel.
PHP must then be compiled with the --with-mcrypt=/path/to/mcrypt
I'm assuming wamp has this already compiled in, you should be able to enable the extension somewhere.

I've got no knowledge of CI so I can't help you there I'm afraid.
