  64. Addresses are given in a comma-separated list. Hyphen-separated
  65. ranges are also allowed.{}
  66. If available, the external 'keyconv' program will be used for address
  67. generation.
  68. Data for the --from-<what> options will be taken from <infile> if <infile>
  69. is specified. Otherwise, the user will be prompted to enter the data.
  70. For passphrases all combinations of whitespace are equal, and leading and
  71. trailing space are ignored. This permits reading passphrase data from a
  72. multi-line file with free spacing and indentation. This is particularly
  73. convenient for long brainwallet passphrases, for example.
  74. BRAINWALLET NOTE:
  75. As brainwallets require especially strong hashing to thwart dictionary
  76. attacks, the brainwallet hash preset must be specified by the user, using
  77. the 'p' parameter of the '--from-brain' option
  78. The '--from-brain' option also requires the user to specify a seed length
  79. (the 'l' parameter)
  80. For a brainwallet passphrase to always generate the same keys and
  81. addresses, the same 'l' and 'p' parameters to '--from-brain' must be used
  82. in all future invocations with that passphrase
