Hi @orapic, Thanks for the PR! |

Ok, should be fixed now. |

Hi, could you explain here, what do you want to check?

Hi, well looking at it twice, that code doesn't make much sense. I will change it to check them all 1 by 1 to the length of the first simshash.

Before using simhases[0], we need to check the length of simhashes to make sure it's not empty. Also since you are using the first element's hashfunc, do we assume all hashfunc should be the same for each element in simahases list?

True, will add some check to look if its empty or not.
Regarding the hashfunc, I think it's safe they must be the same. If they are not, which one do you chose for the new multihash?

Add the possibility to concatenate simhashes to make a larger one.
This way one can make a sort of "signature" where multiple simhashes are combined into one. Also made the tests for it.
Example with 4 simhashes of 32 bits:
