What does this message mean - permission to decrypt item?

Every so often when I have the program open, it displays this message in
a pop-up window:

MS Entourage wants permission to decrypt item "pop.gmail.com" in
keychain "sdou544". Do you
want to allow this?

What does this mean? I have been denying it, what will it do if I allow it?
