Hello Larry, I came across some questions when developing on localhost and enabling https. Xampp's apache configuration file: httpd-ssl.conf, has the following commented out: #SSLRandomSeed startup file:/dev/random 512 #SSLRandomSeed startup file:/dev/urandom 512 #SSLRandomSeed connect file:/dev/random 512 #SSLRandomSeed connect file:/dev/urandom 512 Looking up recommendations, I found out that I should enable the urandom library like so: #SSLRandomSeed startup file:/dev/random 512 SSLRandomSeed startup file:/dev/urandom 512 #SSLRandomSeed connect file:/dev/random 512 SSLRandomSeed connect file:/dev/urandom 512 However, is there a reason why it is commented out? Maybe newer versions of php already implement it somehow or the library was declared somewhere else which means I shouldn't even be doing this myself? I ask this because the php manual says that session.hash_function and session.entropy_file were removed in some newer versions of php and the php.ini file? My second question is why is it 512 and not 256 ? I assume that the number indicates a sha function to be used with php?
