2nd attempt For V6.00.01RC10 Here is a simple (working, but not finished!) demo program for the AES128 function for PicoMites. The program can encrypt and decrypt files of seemingly any length (e.g. text, images, music, etc.). Picomite_AES_File08.zip ( v0.08 RandomKey$() corrected) For strings: AES_String001.zip Comments, criticism, own suggestions, changes and discussion are welcome. With big thanks to Peter!  !

Hi Michael, I wanted to try out your AES FILE encryption but only get an Error: [97] In $=Input$(CH_SIZE,#2) ERROR: Missing Program Statement Have you any suggestions? Greetings Daniel |

Hi Daniel, There seems to have been a transmission error. For me, it shows the following: in$=Input$(CH_SIZE,#2)  Or is "in" a reserved word now? Kind regards Michael causality ≠ correlation ≠ coincidence |

in is a reserved word as it is a PIO instruction |

None of the PIO Instructions can be used as variable names. Internally MMBasic treats them as commands as part of PIO Assemble. e.g. PIO assemble 1,"IN null,32 side 2" 'set ISR to 0, GP1 high (load), ‘GP0 l All these variables will be save internally as Commands. in$="123" out$="123" jmp$="123" wait$="123" push$="123" pull$="123" mov$="123" irq$="123" set$="123" Paste the above in via AUTOSAVE , and then open in the editor and you will see them stored as commands. In and Out are the ones you will most likely stumble accross. In $="123" Out $="123" Jmp $="123" Wait $="123" Push $="123" Pull $="123" Mov $="123" IRQ $="123" Set $="123" F4 H7FotSF4xGT |

@Peter & Gerry Thanks both of you for the confirmation! The strange thing is that the program worked for me (I'm pretty sure it was with V6.00.01RC10). I've just tested again. "In$" is converted to "In $" with V6.01.00b5. Nobody seems to be interested in this topic except Daniel, otherwise I would upload a corrected version.

Ah, ok I understand! So I just have to change the variable name. EDIT: I changed the variable name and now the program works just perfect, thank you! I think this could be a great thing to convert it into a GUI application. I have plenty of use for this, for example in my diary / journal program. But first things first...

Hi Daniel, I would be happy if the code could be of any use to others. I had long since forgotten about this little demo. When I made it, I didn't have HDMI picomites yet. In general, it's not necessary to mention my name if parts of my code are reused. Have fun! Kind regards Michael causality ≠ correlation ≠ coincidence |

Hi Michael, your code is a huge help for me and fits perfectly into my diary application. For now, I implemented it in a way one can select different files or diary entrys to encrypt and decrypt (all in my GUI approach). It works great! And of course I do always mention the work of others, even though this is not a commercial application. This is just for fun, of course. I hope to show some progress at some point  I always do save those cool little test and demonstration programs from the forum on my HDD for later reincarnation Greetings Daniel |
