  Seed phrase utilities:

    Supported seed phrase formats: 'mmgen' (default), 'bip39', 'xmrseed'

    IMPORTANT NOTE: MMGen Wallet’s default seed phrase format uses the
    Electrum wordlist, however seed phrases are computed using a different
    algorithm and are NOT Electrum-compatible!

    BIP39 support is fully compatible with the standard, allowing users to
    import and export seed entropy from BIP39-compatible wallets.  However,
    users should be aware that BIP39 support does not imply BIP32 support!
    MMGen uses its own key derivation scheme differing from the one described
    by the BIP32 protocol.

    For Monero (‘xmrseed’) seed phrases, input data is reduced to a spendkey
    before conversion so that a canonical seed phrase is produced.  This is
    required because Monero seeds, unlike ordinary wallet seeds, are tied
    to a concrete key/address pair.  To manually generate a Monero spendkey,
    use the ‘hex2wif’ command.

    hex2mn             - convert a 16, 24 or 32-byte hexadecimal string to a
                         mnemonic seed phrase
    mn2hex             - convert a mnemonic seed phrase to a hexadecimal string
    mn2hex_interactive - convert an interactively supplied mnemonic seed
                         phrase to a hexadecimal string
    mn_printlist       - print a mnemonic wordlist
    mn_rand128         - generate a random 128-bit mnemonic seed phrase
    mn_rand192         - generate a random 192-bit mnemonic seed phrase
    mn_rand256         - generate a random 256-bit mnemonic seed phrase
    mn_stats           - show stats for a mnemonic wordlist

  Utilities for viewing/checking MMGen address and transaction files:

    addrfile_chksum        - compute checksum for MMGen address file
    keyaddrfile_chksum     - compute checksum for MMGen key-address file
    viewkeyaddrfile_chksum - compute checksum for MMGen key-address file

                             files in human-readable form

  File encryption and decryption:

    MMGen encryption suite:
    * Key: Scrypt (user-configurable hash parameters, 32-byte salt)
    * Enc: AES256_CTR, 16-byte rand IV, sha256 hash + 32-byte nonce + data
    * The encrypted file is indistinguishable from random data

    encrypt - encrypt a file

                            returning the decrypted key in hex format
