There was a problem hiding this comment.
I could see moving most of this method into libbitcoin/src/utility/random.cpp similar to new_seed

UPDATE: This is no longer relevant, as seed changes have been reverted. This generates valid electrum mnemonics verified against electrum 3.0x: The default entropy size for electrum mnemonics is 132 bits. I didn't want to automatically override the default (of 192 to 132) if --electrum was used in the case that -b 192 was used specifically, so for now, the recommended usage is to specify -b 132 as in the example above. Thoughts? |

Ah, this needs a unit test as well, will add one. |

use only what is required. By default, 132 bits of entropy are used to match the default for electrum 2.x+. If more input entropy is provided and more entropy for the electrum-mnemonic is desired, a -b,bit-length option is provided to specify how much.

Update seed command to support electrum mnemonics with 132 bits of entropy (the default for electrum 2.x+) or more (resolves #499)
