No dude, I meant is there a way of it converting the .addauth nick:pass into the bXl0d2l0dGVybmFtZTpteXBhc3M= then passing it onto the Script.
So you'd do .addauth nick:pass then the script iself, would encrypt the nick:pass part and them store it?
Example:
/msg Bot .addauth nick:pass
nick:pass >> bXl0d2l0dGVybmFtZTpteXBhc3M=
bXl0d2l0dGVybmFtZTpteXBhc3M= is sent to twitter, and also stored in the TwitterAuth and in the hashfile.
