I have just finished analysis of license decoder and collected enough information to rewrite it into C. If anyone has A-type license code and doesn't mind sharing it with me, please send me PM. This would speed up the whole process. |

It will be a long time until as many A models are sold. |

It's only 48 bits, as far as I can see... |

The new public key is 0xA51BF373712F7D and the private key (that matches old Rigol ECC parameters) is 0x888E77EE47C50A. I don't have DS2K-A scope yet, so I can't confirm if this key will work with existing keygens. --- End quote --- |

yes, but there's something else missing since this private key doesn't work yet I think that's what zombie28's working on atm |
