Split-key Vanity Address Generation

This tool supports split-key vanity address generation.

Step 1, Alice generates a key pair on her computer:

$ ./keyconv -G
Pubkey (hex): 044a9fef408ec4db7e264c8f1bfc712a9f6089025bd1980660f7f72c731b7d4c6a6fa5e0fe2174aaa02fffb6ed4a5735fc3109bae2fefe060d8a09bdb8f819f38b
Privkey (hex): B6761A9A575C3C125F24B09A7ADB5F3613BB654F73ADB7097657D737FCD1C310
Address: 1AF518xd1zBNCQh2q1qsneaxAs5nPyXzNf
Privkey: 5KCeK2bzDq2YzUMfwUrNp79mEsk2eeY1dzYtCTTxEgbbFav8RtA

Then, Alice send the generated public key and the wanted prefix (for example 1ALice) to Bob. Nevertheless, Alice has to keep safely the private key and not expose it.

Step 2, Bob runs vanitygen++ (or oclvanitygen++) using the Alice's public key and the wanted prefix (1ALice).

$ ./vanitygen++ -P 044a9fef408ec4db7e264c8f1bfc712a9f6089025bd1980660f7f72c731b7d4c6a6fa5e0fe2174aaa02fffb6ed4a5735fc3109bae2fefe060d8a09bdb8f819f38b 1ALice
Difficulty: 259627881
Pattern: 1ALice
Address: 1ALicexPg59dVvYgtAP8QCphdrFep6nRwy
PrivkeyPart: 5KAuZAyz71TFwgDpiBPyMJX6YFxKyJEJDsr2tNr8uraw6JLBMpQ

Bob sends back the generated PrivkeyPart to Alice. The partial private key does not allow anyone to guess the final Alice's private key.

Step 3, Alice reconstructs the final private key using her private key (the one generated in step 1) and the PrivkeyPart from Bob:

$ ./keyconv -c 5KAuZAyz71TFwgDpiBPyMJX6YFxKyJEJDsr2tNr8uraw6JLBMpQ 5KCeK2bzDq2YzUMfwUrNp79mEsk2eeY1dzYtCTTxEgbbFav8RtA
Address: 1ALicexPg59dVvYgtAP8QCphdrFep6nRwy
Privkey: 5JcX7HgrPxEbYKcWhtBT83L3BHcdJ8K8p8X1sNHmcJLsSyMNycZ
