AES Encryption and Setting Result In Editbox

[Kracker]

I downloaded it today from the link provided on the Fusion Wiki site:

Maybe it also might have something to do with your MMF2 version. Try updating it to 251 and see if that helps. After a little thought on the Blowfish random key issue I remember reading either on the forums or in the help file that the Blowfish Random Key Generator feature sometimes produces characters that are not viewable.

I took this in to consideration when designing the first version of the app. I stored the random key as an Alterable String and then when it displayed in the editbox I pulled the info from the Alterable String. When I set the key I made sure to pull the data straight from the Alterable String and not from the editbox as I knew there may be some characters that were generated by the Blowfish Random Key Generator that would not be picked up in the editbox.

In any case, all is working great. I even compiled the app to an exe to see if it will work outside of the safe MMF2 environment and it works fine.

I have downloaded the String Generator object from the link you provided, and I now experience the same issues you did. I now doubt it had anything to do with the build.

[Kracker]

I'm guessing it may have to do, possibly, with the order or way the expressions were entered in that first condition. I can mouse over and modify all the other conditions except for that first one.

I did notice one thing. The way you limited the edibox text to 16 characters was using Len. There's another way. The way I do it is I do a condition of "At Start of Frame" I right click under the editbox that's for the key, go to Control > Limit text size, and then set the value to 16.

[Richard_Pikk]

It was the same thing for me in your example, the actions referencing the String Generator object could not be viewed or edited. With the newer version of the object the example behaved as intended.

The reason I chose the Len method is because it will also prevent the use of keys shorter than 16 characters, which will no doubt happen at some point if users are allowed to specify their own keys.

[RickyRombo]

Besides, I think the "Limit Text Size" doesn't prevent pasting more than 16...

[Kracker]

That's interesting about the 16 characters. And I just learned something new on how to limit characters +/- character lengths. Does the key have to be 16 characters or can it be less than 16 characters for AES?

[Kracker]

Besides, I think the "Limit Text Size" doesn't prevent pasting more than 16...

I've tested it out and only "Limit Text Size" will prevent more than 16 characters in the editbox. It doesn't matter whether you manually type in the characters or attempt to paste more than 16 characters. If you past more than 16 characters with "Limit Text Size" then only the first 16 characters will paste.

Len does not prevent more than 16 characters from being typed or pasted. It is good, however, if you want to create a condition that checks to see if there's more than 16 characters in the editbox and then lets a person know (string, dialog box, etc) that they have too many characters in the editbox.

You can also use Len as Richard has used it. Use it as a condition so that if the characters exceed the limit specified in Len then it does not perform the action (i.e. encrypt the text).

[Richard_Pikk]

Yes. I think in such cases it would be best to check the contents of the input in a condition to prevent the AES object from performing its actions unless the key is correct, and also to implement some routine to warn the user if they type in a key that is not the requred length.

Just to make sure, the key for AES 128 must be exactly 16 characters (128 bit) long.

Hi Everybody,

a few months ago i developed an Encryption/Decryption-App. Perhaps someone would be interessted in testing it.

The "Source" is for Free and can be edited to any extend. It could also be used as a Template for your own Encryption-App.

Important: In that Build, the "File-Encryption" is not implemented yet (code-wise), but the Controls are already on the GUI. The String-Encryption/Decryption and saving of Keys does already work.
I' ve implemented some "advanced" features already like checking for correct Key-Length and checking for duplicated Key-Names. The Keys can also be stored to an encrypted Database for later usage.

Here' s the MFA:

Sorry for bumping an old thread but does anyone know where I could find Jahkri's MFA file, preferably the latest version? The link above is dead.
