I think that I shall never see. A graph more lovely than a tree.

Why is verification using DSA slower than verification with RSA? @HenrickHellström: Thank you for the response. |

Why is verification using DSA slower than verification with RSA? A quick follow up, is there a big difference in authentication and verification complexity between RSA with a 1024 modulus and a 2048 modulus? |

What do recent announcements about solving the DLP in $GF(2^{6120})$ mean for RSA Thanks for the very clear explanation! |

May the problem with DES using OFB mode be generalized for all feistel ciphers Thank you for the additional information!! |

May the problem with DES using OFB mode be generalized for all feistel ciphers Thanks for the response! But with DES, if i encrypt P1 with $k$ i get C1, if i encrypt C1 with $k$ agian, i get back P1? Or only when DES is used with "weak keys"? |

May the problem with DES using OFB mode be generalized for all feistel ciphers Thank you for the response! The reverse operation in the feitel network is for OFB a "blackbox". But reversing the subkey is a property of the feistel network, you have to be able to decrypt back? The problem here is using a feistel cipher on OFB-mode and how it "leaks" information. |
