Crypto-mnemonic creates random pass phrases or (hexadecimal UIDS) of specified strength which are human readable and rememberable. It is compatible with the javascript version: mnemonic.js which we use for our crypto wallet.

Add this to your application's shard.yml:

dependencies:
  crypto-mnemonic:
    github: Axentro/crypto-mnemonic

require "crypto-mnemonic"

You can generate a 96-bit mnemonic, i.e. 9 words or 3 random 32-bit unsigned integers:

m = Mnemonic.new(96)
m.to_words
["grey", "climb", "demon", "snap", "shove", "fruit", "grasp", "hum", "self"]

You can also obtain the random sequence or the 96-bit number in hexadecimal notation as follows:

m.seed
[174975897_u32, 171815469_u32, 1859322123_u32]

m.to_hex
"0a6deb990a3db22d6ed3010b"

Finally, from a list of words or a hex string it is possible to recreate the mnemonic that generated them:

m = Mnemonic.from_words(["grey", "climb", "demon", "snap", "shove", "fruit", "grasp", "hum", "self"]);
m.to_hex;
"0a6deb990a3db22d6ed3010b"

m = Mnemonic.from_hex("0a6deb990a3db22d6ed3010b")
m.to_words
["grey", "climb", "demon", "snap", "shove", "fruit", "grasp", "hum", "self"]

When working with Mnemonic you must use either 32/64/96/128/256 etc for the bit strengths. 96 is the default.
