Asymmetric Encryption

RSA-768: Nothing to worry about

I have been meaning to write up a short post about this for a while, but thanks to the start of a new school term I have been a bit busy. If you have seen the security news in the last month or so you will know that RSA-768, a 768bit or 232 decimal digit asymmetric key, has been broken (factored). This has important security repercussions for all of us because it is these public key algorithms like RSA, or ElGamal, that guard our online transactions, and e-mail conversations.
