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.

Migrated to a new PGP key

Well GPG to be more accurate 😉 As my existing key was set to expire at the end of this year I have issued myself a brand new one! After much though I finally decided that creating a new key from scratch was the best idea, rather than simply adding a new subkey, because I wanted to move away from DSA/ElGamal toward RSA primarily because of the weakening of SHA1. If this all sounds like gibberish to you then don’t worry, the details aren’t nearly as important as the security provided by my new key.

Pondering the best way to migrate to a new PGP key

Well its almost time for me to create a new PGP key. My current key for tyler at tylerburton dot ca is set to expire at the end of the year and I am trying to determine what the best way to migrate to a new key is. Some people suggest simply adding a new encryption sub key and then changing the original signing key’s expiry date so that individuals wishing to verify your signatures can continue to do so uninterrupted.
