Beginning with this commit, every MMGen wallet now has a two sets of associated subwallets with “long“ and “short” seeds. MMGen wallets and subwallets are functionally equivalent and externally indistinguishable. This has benefits, especially for real-world security, as well as drawbacks. For more information, see the `mmgen-subwalletgen` help screen: https://github.com/mmgen/mmgen/wiki/subwalletgen-[MMGen-command-help] This patch provides subwallet generation functionality and subseed display utilities. Support for transaction signing and address generation using a subwallet's parent wallet will be added in a forthcoming patch. Examples: # Create a bogus wallet in mnemonic format for testing purposes: $ echo $(yes bee | head -n24) > bogus.mmwords # List the wallet's first five subseed pairs: $ mmgen-tool list_subseeds 1-5 wallet=bogus.mmwords Parent Seed: DF449DA4 (256 bits) Long Subseeds Short Subseeds ------------- -------------- 1L: FC9A8735 1S: 930E1AD5 2L: 62B02F54 2S: DF14AB49 3L: 9E884E99 3S: AD3ABD98 4L: DB595AE1 4S: 3E885EC4 5L: 36D5A0D1 5S: 30D66FF5 # Generate the 5th short (128-bit) subwallet from the wallet: $ mmgen-subwalletgen bogus.mmwords 5S # Same as above, but output subwallet to mnemonic (seed phrase) format: $ mmgen-subwalletgen -o mn bogus.mmwords 5S ... Mnemonic data written to file '30D66FF5[128].mmwords' # View the subwallet's seed phrase: $ cat 30D66FF5[128].mmwords object capture field heart page observe road bond mother loser really army # Generate 10 addresses from the subwallet seed phrase: $ mmgen-addrgen 30D66FF5[128].mmwords 1-10 ... Addresses written to file '30D66FF5[1-10].addrs'
