as a file. FindETH will search through the most common derivation paths (currently 31 ), offered by some of the popular wallets. The inputs to this function are the pseudorandom function (HMAC-SHA512), a password (our mnemonic sentence), a salt, and the number of iterations the hash function will run (2048). When you put in the 23 words the code comes up with the 24th word as "type" which is not correct. The resulting integers should range from zero to 2047 (i.e., ba2int(bitarray(11111111111)) == 2047).
