comment Isn't all security “through obscurity”?
If you keep everything secret then you can only communicate with yourself... The point is not to rely on something that your adversary has a chance of finding out or to assume that simply because you're not making it publicly known it will not be discovered.

comment 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.

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

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

@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...

Issuing certs 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.
