Moises,
1) From who are you trying to protect this information? Casual users or more experienced attacker?
2) What is the value of the information if it is stolen / compromised? High or low?
3) For how long is the information valuable i.e. for how long must it be protected?
In the End, we will remember not the words of our enemies, but the silence of our friends - Martin Luther King, Jr.
