Redrose vanity address generation service
To do so, it is simple :
1. Post a request here. The address must start with 1 and must follow
these rules (
https://en.bitcoin.it/wiki/Base58Check_encoding#Base58_symbol_chart).
2. Go to
https://www.bitaddress.org/ and then move your mouse or type on the keyboard in the field until reaching 100% and wait a second.
3. Download the page, verify it and run it on local mode. You must have the same public and private keys than the online version.
4. Click on "Vanity Wallet" under "Single Wallet", higlighted in white, and then click on the "Generate" next to "Generate your "Step1 Key Pair"".
5. Post here your public key and the desired prefix of your address. Keep the private key in a safe place. It will be needed in further steps after the partial key has been generated.
6. I will send you the partial private key. Once done, go back to bitaddress.org and click on "Vanity Wallet".
7. Head toward "Step 2 Calculate your vanity wallet". In the first blank, insert the private key you saved, in the second, the partial private key I send to you. Click then on "Calculate Vanity Wallet".
8. Import the Vanity Private Key (WIF) in your favourite wallet. You're done !
Service is now free for the 25 first request, proven they are not too hard for me to execute. Difficulty up to about 20 000 000 000 is acceptable, but still ask, I may go a bit more.
Thank to shorena for its thread [1] and OmegaStarScream for pointing it to me [2].
