How to detect if I use "AES" or "TKIP" as encryption method for "WPA-PSK"? Client or AP requirement?

Currently I am connected to an Access point.

I know that I am using as Network Authentication "WPA-PSK".

However how do I find out which encryption method "AES" or "TKIP" I am currently using?

Is the encryptiob method a requirement of the remote accesspoint hardware or can every local WLAN client
individually decide how he wants to communicate with the Accesspoint?

The encryption algorithm is set in the router's (AP's) configuration
utility. All clients must use the same algorithm. Thus, if you have at
least one client that *cannot* use AES, then you'll have to configure
the AP to use TKIP, somewhat degrading the security of the wireless network.

If your router doesn't offer a sub-option for encryption then you will
be using tkip.

It depends on what the access point is set to accept. Some might
accept WPA-PSK connections only. Others might accept only WPA2-PSK and
some will accept either WPA-PSK or WPA2.PSK
