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