 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Try this PicoMite.zip Should now do > 16 bytes for ECB |

Hi Peter, it is accomplished. It works, if I have time I'll test the rest too. It's almost Christmas   I would like to take this opportunity to thank you for your great support!  Bishop |

Correction: Please correct my (or rather Peter's) program above. Inc in$,String$(16-Len(in$) Mod 16,0) should be: Inc in$,String$((16-Len(in$) Mod 16)Mod 16,0) to pad the 16-byte blocks with zeros. Michael causality ≠ correlation ≠ coincidence |

Hi, short test with "CBC" - worked Init. vector: Dim float iv(15)=(&HD7,&H5D,&H0D,&H44,&HD4,&HA7,&H44,&H55,&HD7,&H33,&HB3,&HF8,&HA5,&H3A,&H98,&H23)  Bishop |

Thank you so much! This is a great new feature. I didn't even dare hope for something like this. @Peter: Will there be SSL / https for WebMite at some point? Matthias |

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.). File deleted to adapt to firmware changes. Will upload again. (sorry!) With big thanks to Peter!  Regards Michael Edited 2024-12-21 21:28 by twofingers causality ≠ correlation ≠ coincidence |

Sorry Michael but I've changed the mechanism in light of the info from Jim. Please see the release thread for more details. |

@Peter Thanks for the info! I already saw that in the release thread. In the demo program above I don't use the "initialization vector". I don't know if that changes anything? Michael causality ≠ correlation ≠ coincidence |
