Why hash or salt when signing? Thanks. So if my message is short enough – there's no need. Correct? |

Why hash or salt when signing? Thanks. But I'm referring to signing, and so it seems unlikely (correct me if I'm wrong) that someone will have a table for a rainbow attack for all 100 bit combinations. |

How to sign a message using RSA? @CodeInChaos So you're saying it can't realistically be done in a simple manner (i.e. without spending a week studying cryptography), right? By the way, if you have some solution as to how I can create an activation key in a web hosting environment – where they have RSACryptoServiceProvider blocked – I'd be happy to hear about it. |

Is a RSA-signature of some identifying data a safe way to implement a license key? @Polynomial Thanks for that important information! |

Is a RSA-signature of some identifying data a safe way to implement a license key? @PaŭloEbermann Thanks for bearing with me. I edited the question for (a little) clarity. Knowing the ID is not important, because the program will retrieve the real ID of the operating system. See also my previous comment (to this.josh ) |

Is a RSA-signature of some identifying data a safe way to implement a license key? @this.josh If someone is computer-savvy enough to do that – he’ll probably be able to de-compile the program anyway, and remove the security check. My main goal at the moment is to thwart someone from creating a program that will create license keys when given a product ID. |
