No - this is more a simple and easy to use service that relies on the trust of me as an operator.
In crypto, we have the saying "verify, don't trust" (I don't know the original source).
I have quite a bit of credibility in a lot of industries so I think it's not a problem.
You have NO credibility here. For people to trust you with private keys, you'll need to have a trust level comparable to
casascius, and even then, the keys should be generated offline instead of on a server that transfers the keys over the internet.
For those people who really are paranoid about security, then this probably isn't for them
For anyone who understands the very basics of not losing their coins, this isn't for them.
UPDATE: We now support split-key on our website!
Split key should be the only option, so you can PROVE you're honest instead of having people "trust" you.
