Please Help Coders

Hi guys, this is really important to me! i am trying to find a way to hacking a FLASH game!
And i already found how to change the value of the score, but i think is encrypted or something like this

data=******************%2FAMoEYuWZ1JV -19seconds
data=******************%2FJxO6qgdRnAF - 8sconds
data=******************%2FKZ9X%2BgHlqbk - 29seconds

the rank is by the time, higher time - higher rank!
but i dont know how to make an higher code :S
i know sounds confusing but i really need help!

*** - becouse its the same on every code, and its the user "code"

data=ILOVETAYLORSWIFT%2FAMoEYuWZ1JV -19seconds
data=ILOVETAYLORSWIFT%2FJxO6qgdRnAF - 8sconds
data=ILOVETAYLORSWIFT%2FKZ9X%2BgHlqbk - 29seconds
