I need to "encrypt" (is it the right term?) the text messages in the source-code, in order to avoid been changed with some kind of "decompiler" or "resource hacker" tool. I already use a function for this, but the texts get 3 times longer (and so my app size). I do NOT want any complex function, just something simple as possible, to make texts unreadable, and with the same length as before (or less, if possible ;-))
Ohhh... I forgot to say... the messages have accents and other special characters, like á, ô, ç...
