Certificate == signed public key In addition, the word "plaintext" is used in contrast with "ciphertext", that we do not have in the case of signatures. To answer your question, the message is not part of the certificate, while the public key used to verify the signatures is. |

Certificate == signed public key This is NOT a secure signature scheme. If you have two messages signed, you can compute a signature of their product simply multiplying their signatures. |

How to find an element of high-order in an RSA group? Choose a random element. Since its order must divide the group order, if it is not 2 or 4, then it must be as big as the smallest between p and q. However, I do not know about how difficult the discrete log is in such group |

How to find an element of high-order in an RSA group? If you choose a SAFE rsa modulus (one written as (2p+1)(2q+1) with p,q,2p+1,2q+1 all primes) the order of the group is 4pq and is relatively easy to find elements of high order |

Two files encrypted with related data versus one file Thanks for the suggestion! I briefly updated the answer to include that, feel free to expand and edit it if you wish. =) |

Two files encrypted with related data versus one file You are right. AES itself is just a (trapdoor) permutation. I think the way AES is used in Truecrypt (XTS mode) is IND-CPA. |
