Hi everybody!
I've made a vanity onion address generator that's available for public use with low-fees. The whole system works perfectly right now although I'm working on extending the feature set (I'm open to suggestions!).
Whether you're looking to create your own marketplace/darknet site, or need a custom name to communicate with vendors/clients over TorChat, my service can whip up an RSA key custom for you.
Obviously, when having a 3rd party generate your keys, there is the chance that your keys could be stolen. I assure you that your keys are 100% wiped from my servers after you have claimed them. There is no way that I can verify this for you obviously, but I'm making it clear who I am to help give some level of trust.
If you have any questions about the service, feel free to ask, I'll be glad to answer as soon as possible.
