mnemonic, seed or password
USAGE: mmgen-addrgen [opts] [infile] <address list>

-e, --echo-passphrase Echo passphrase or mnemonic to screen upon entry
-H, --show-hash-presets Show information on available hash presets

instead of 'keyconv'
-l, --seed-len N Length of seed. Options: 128, 192, 256
(default: 256)

hashing password (default: '3')

-q, --quiet Suppress warnings; overwrite files without
prompting
-S, --stdout Print addresses to stdout
-v, --verbose Produce more verbose output
-b, --from-brain l,p Generate addresses from a user-created password,
i.e. a "brainwallet", using seed length 'l' and
hash preset 'p' (comma-separated)
-g, --from-incog Generate addresses from an incognito wallet
-X, --from-incog-hex Generate addresses from incognito hexadecimal wallet
-G, --from-incog-hidden f,o,l Generate addresses from incognito data in file
'f' at offset 'o', with seed length of 'l'
-m, --from-mnemonic Generate addresses from an electrum-like mnemonic
-s, --from-seed Generate addresses from a seed in .mmseed format
Addresses are given in a comma-separated list. Hyphen-separated ranges are
also allowed.
If available, the external 'keyconv' program will be used for address
generation.
Data for the --from-<what> options will be taken from <infile> if <infile>
is specified. Otherwise, the user will be prompted to enter the data.
For passphrases all combinations of whitespace are equal, and leading and
trailing space are ignored. This permits reading passphrase data from a
multi-line file with free spacing and indentation. This is particularly
convenient for long brainwallet passphrases, for example.
BRAINWALLET NOTE:
As brainwallets require especially strong hashing to thwart dictionary
attacks, the brainwallet hash preset must be specified by the user, using
the 'p' parameter of the '--from-brain' option
The '--from-brain' option also requires the user to specify a seed length
(the 'l' parameter)
For a brainwallet passphrase to always generate the same keys and addresses,
the same 'l' and 'p' parameters to '--from-brain' must be used in all future
invocations with that passphrase

Transaction inputs are chosen from a list of the user's unpent outputs
via an interactive menu.
Ages of transactions are approximate based on an average block creation
interval of 8.5 minutes.
Addresses on the command line can be Bitcoin addresses or MMGen addresses
of the form <seed ID>:<number>.
To send all inputs (minus TX fee) to a single output, specify one address
with no amount on the command line.

-m, --from-mnemonic Generate keys from an electrum-like mnemonic
-s, --from-seed Generate keys from a seed in .mmseed format
Transactions with either MMGen or non-MMGen input addresses may be signed.
For non-MMGen inputs, the bitcoind wallet.dat is used as the key source.
For MMGen inputs, key data is generated from your seed as with the
mmgen-addrgen and mmgen-keygen utilities.
Data for the --from-<what> options will be taken from a file if a second
file is specified on the command line. Otherwise, the user will be
prompted to enter the data.
In cases of transactions with mixed MMGen and non-MMGen inputs, non-MMGen
keys must be supplied in a separate file (WIF format, one key per line)
using the '--keys-from-file' option. Alternatively, one may get keys from
a running bitcoind using the '--force-wallet-dat' option. First import the
required MMGen keys using 'bitcoind importprivkey'.
For transaction outputs that are MMGen addresses, MMGen-to-Bitcoin address
mappings are verified. Therefore, seed material for these addresses must
be supplied on the command line (but see '--all-keys-from-file').
Seed data supplied in files must have the following extensions:
wallet: '.mmdat'
seed: '.mmseed'
mnemonic: '.mmwords'
brainwallet: '.mmbrain'

to disable this option, then specify '-r0' on the command line.

-g, --from-incog Generate wallet from an incognito-format wallet
-m, --from-mnemonic Generate wallet from an Electrum-like mnemonic
-s, --from-seed Generate wallet from a seed in .mmseed format
By default (i.e. when invoked without any of the '--from-<what>' options),
mmgen-walletgen generates a wallet based on a random seed.
Data for the --from-<what> options will be taken from <infile> if <infile>
is specified. Otherwise, the user will be prompted to enter the data.
For passphrases all combinations of whitespace are equal, and leading and
trailing space are ignored. This permits reading passphrase data from a
multi-line file with free spacing and indentation. This is particularly
convenient for long brainwallet passphrases, for example.
Since good randomness is particularly important when generating wallets,
the '--usr-randchars' option is turned on by default to gather additional
entropy from the user. If you fully trust your OS's random number gener-
ator and wish to disable this option, specify '-r0' on the command line.
BRAINWALLET NOTE:
As brainwallets require especially strong hashing to thwart dictionary
attacks, the brainwallet hash preset must be specified by the user, using
the 'p' parameter of the '--from-brain' option. This preset should be
stronger than the one used for hashing the seed (i.e. the default value or
the one specified in the '--hash-preset' option).
The '--from-brain' option also requires the user to specify a seed length
(the 'l' parameter), which overrides both the default and any one given in
the '--seed-len' option.
For a brainwallet passphrase to always generate the same keys and
addresses, the same 'l' and 'p' parameters to '--from-brain' must be used
in all future invocations with that passphrase.
