[Cryptography] Thoughts about keys

[Guido Witmond]

Hi Peter,

We really have different designs. I'll comment inline.

If I read it correctly, each participant has one *single identity*?

Eccentric does it the other way around, with ecca, you have one or more
different identities at *each* site. At least one. But if you want to
blog different topics under different id's, no problem. Create another
account.

I think there are good reasons for having multiple *independent*
identities. For example, if your writings get too hot for the blog site
owner and they close one account, it doesn't affect the other accounts.

If you want, you can destroy the private key so there is nothing that
traces you to that account.

Or if you want, you can post a proof of ownership of the private key of
the account, to show that the site censured a really good post. They
closed the account but can't invalidate your key. Again, other accounts
are still unaffected.

As you and I have never met, I can't validate your photo, neither half
your claimed penis size. ;-)

How do I know it's not a Man in the Middle using your picture?
