Description

Hello guys, can you please add BitGo and Block.io GPU-based recovery? Both recoveries are possible in BTCRecover, but it is not GPU-based. Can anyone add these two wallets to jtr or help with faster recovery? I will sponsor it and give you $500 for each wallet, a total bounty of $1000.

Research direction

Start by reviewing the existing BitGo and Block.io recovery support in BTCRecover and the repository's current wallet or hash-mode implementations. Then identify how existing GPU/OpenCL recovery modes are structured and what inputs the two wallets require. Done means both wallet types have supported GPU-based recovery paths in John the Ripper, with validation against known recovery cases.
