[Gambas-user] How to decrypt a text? Any suggestions?

[Hans-Martin Bundeshund]

Hello group,

I hope that I don't ask too many questions here and i will be not filtered ;)


I have a database with usernames and passwords stored with mysql. I want to 
write the passwords not in plain text as I do quite now. 

Any ideas how I can easely decrypt (and encrypt) the plain text using gambas? 
(I do not want a call to an external script/programm just to use a litle code 
inside)

Thankfull

HM
