Secure password storage

[fearoffours]

Hi there.
I'm developing a small application in which the user will input a username and password for access to the last.fm webservice.
I'd like to be able to offer the user the option to log in to multiple accounts, and so had thought the best way to do this was to store username/password in an instance of e32db/e32dbm.
Is it safe/secure to store these in an unencrypted form in either of these forms?
If I wish to go about encrypting the data, what is the best way to do this, do you know of any examples where people have done the same/similar in pyS60?
If you were using an application like this, would you feel worried if this data was stored in the database as an unencrypted string?
Thanks in advance!

Search the forum for 'AES'. I am not sure if it would work with 1.9.x though.

thanks, I'll see if I can get that working on 1.9
