how safe is the 256 bit encryption used in bank transactions @DavidCary: I think what I wanted to say a year ago :-) is: "the statement that factoring is NP hard" is incorrect. Since then the answer has been edited and that statement removed... I don't know of a proof showing that factoring isn't NP hard. |

how safe is the 256 bit encryption used in bank transactions factoring is not NP hard. It's just there is no known algorithm that can factor in polynomial time but AFAIK no one has proven it can't be done. en.wikipedia.org/wiki/Integer_factorization |

If the encryption algorithm broken or analysed, can an attacker find my password? The question seems very vague. What is the exact scenario? |

What is the danger of hosting your SSL certificate yourself? @Bruno: Sure. I just wanted to point that as a possibility. Your own CA is the best solution as long as all clients are on the domain and you can push the CA cert to them using directory services... |

What is the danger of hosting your SSL certificate yourself? Encryption without authentication is not very useful because anyone can get in the middle of the channel, pretend to be the other party, and decrypt the entire communication. That is the biggest issue with using a self signed cert that clients can not verify through some other means. |
