I guess it depends on the cost to you or your organization of having someone you don't want/know getting access to information that should be password protected. A thorough argument for bcrypt rather than md5/SHA is made here: http://codahale.com/how-to-safely-store-a-password/ I use it because for roughly the same number of lines of code passwords are much harder to crack.

You can do that using Morphic, but this is quite tricky (in fact, you need to remove all the sub widgets, then change their layout and re add them) Spec provides a simpler way to do it.

Why not just something like | password cryptedPassword | password := UITheme current passwordEntryIn: World text: 'Password' title: 'Title' entryText: ''. cryptedPassword := MD5 new initialize hashStream: password readStream ?

For an example of the login process using Pharo + Seaside see http://www.squeaksource.com/TFLogin Which you can probably adapt for just Pharo To store the passwords, if you're on linux, use the bcrypt implementation in the PasswordHashingFFI package from here: http://www.squeaksource.com/Cryptography.html I'd be interested in getting PasswordHashingFFI working on Windows or MacOSX so would help if I can. But using it makes your implementation depend upon an external library you'd likely have to find and supply for users. On 02/01/2013 03:36 PM, J. P. L.

Most of the GUI is based on UITheme examples, yet I wasn't able to figure out about user/password prompt.
